installation (for qualified personnel only)

■ "Comet" cubicles are equipped with 4 wheels for moving over short distances

and with jacks to immobilize the unit. The jacks must be raised prior to

repositioning a cubicle;

■ operating temperature range: 0° to 30°C at rated output.

Important:

■ the battery is of the sealed type. Battery storage or prolonged shutdown

of Comet should never exceed 3 months at 20°C without recharging, for a

battery initially at 100% charge. Battery recharge requires system start-up.

The battery warranty is void if the 6 month recharge interval is not

respected;

■ battery life is extended when it is installed in a room with an ambient

temperature of 15 to 25°C. Above 25°C, battery life reduced by 50% for

every additional 10°C;

■ heat loss resulting from Comet operation must be taken into account when

sizing the ventilation system. See the Appendices;

■ connections are made through the bottom section in the back or the front,

depending on the type of Comet;

■warning in compliance with EN 50091-2: this product is sold through limited

sales channels to installers or well-informed users. Installation restrictions or

additional measures may be necessary to prevent electromagnetic disturbances.

special precautions

installation (cont')

Note:

For Comet series 31 15/20kVA and Comet series 33 units, a clearance "e" of

5mm is required to the left of the optional cubicles for door opening.

■ensure that clearance L1 to the left of Comet is greater than L for access to the

battery cells and L2 greater than 100mm (for ventilation);

■ensure that clearance P1 in front of Comet is greater than P for servicing via

the front;

■ connection cables must be of th flexible type and sufficiently long to enable

forward movement of Comet without disconnection (allow an extra 1.5 meters);

■ additional cubicles (extended battery, auxiliaries, etc.) must be placed to the

right of Comet. If the above installation conditions are not respected,

maintenance and servicing of the unit may require system shutdown.

■ load cables must be run separately from all other cables (power supply or

computer system interconnection cables). They should not pass near

interference-emitting equipment or sensitive loads;

■ if Comet is installed with the "Teleservice" option, a telephone connector and

power supply must be provided for the modem used with it.

Connection cables should enter at the bottom:

■ in the back for Comet series 11 and series 31 5/7.5/10kVA;

■ in front for Comet series 31 15/20 kVA and series 33 10/15/20/30kVA.

connection of power cables (figures 10 to 14)

Make sure the unit is powered down and disconnected from all input power

before making connections to the terminal blocks at the front or back of the

cubicle (depending on the type of Comet).

For protection of life and property, earth wires should always be connected

first.

For Comet 31 series or Comet 33 series devices, the Mains power supply

must be with a neutral cable.

For Comet 33 series, the neutral may be reconstituted by a complete insulation

transformer option (a transformer with a triple-point structure).

Neutral system: identical upstream and downstream neutral systems (no

galvanic isolation). Comet can be used with all types of neutral systems, on the

condition that standard practices be respected.

■ check that AC input power circuit breaker, installed upstream on the low voltage

switchboard, is in off (O) position;

■ check that the input power switch 1and the battery circuit breaker 4are in

off (O) position.

Connection sequence for 5 kVA Comet:

■open the protective cover 44 (secured by 2 screws) and the connection cover

panel 13 (secured by 6 screws);

■strip the duct of the AC input power and load cables over a length of 7 cm;

■strip each wire over a length of 1 cm;

■insert the cables of the AC input power and load through the bushings of the

connection cover panel;

■connect the cables of the AC input power to "Mains 1" XR1 terminal block in

the order shown on the label;

■connect the load cables to the "load" XR2 terminal block in the order shown on

the label;

■connect the various options as shown in the relevant section for each one in

this manual;

■when the cables have been connected, the duct of each cable must be

tightened by a binding band against the horizontal binding bar placed beneath the

terminal block in order to protect the conductors from tensile loads;

■put back the connection cover panel 13 and the protective cover 44 .

This button enables the user to stop buzzer 17 operation. Detection of a new

alarm will set the buzzer off again.

This button clears the faults stored in memory. Clearing of alarms in memory is

accepted only once the alarm conditions themselves have been cleared.

This button authorises forced operation or shutdown of the inverter 7.

Forced shutdown: press simultaneously and for three seconds the security

button 26 and the "inverter off" button 23 .

Forced operation: press simultaneously and for three seconds the security

button 26 and the "inverter on" button 22 .

This key also controls a battery manual test: press simultaneously on the safety

key 26 and on the buzzer stop key 24 for 3 seconds.

Important: this function causes the battery to discharge completely in order to

update the battery monitoring parameters.

In the event of a network power cut, the uninterrupted battery power supply

returns to normal operation. The self-operating time is thus reduced.

Alarm, fault and status messages are displayed as numerical codes. See chapter

"alarms" for the meaning of the codes. The alarm-code equivalence table is also

displayed on the door or at the back of Comet.

operation (cont')

battery duration

During an AC input power failure, the duration of inverter operation on battery

power depends on:

■ the rated capacity of the battery;

■ the power drawn by the load;

■ the battery temperature;

■ the age of the battery.

The rated backup time corresponds to a minimum for a new battery and with the

inverter operating at the rated load.

The real backup time, which depends on the power drawn, may be greater if the

inverter operates at less than full rated load. It is possible, during operation on

battery power, to increase the battery backup time by reducing the power drawn

by the load (shedding of non-priority circuits).

Comet has a battery monitoring function that calculates the remaining backup

time. This function may be implemented with a communications option.

A low battery shutdown warning signal is available via the standard

communication connector 15 for remote indications. It warns the user of

upcoming battery shutdown at a user-determined level of remaining power.

On the UPS itself, the buzzer 17 beeps louder and more rapidly, and the

orange "battery status" light 20 flashes.

The end of battery power occurs when the battery is fully discharged. At this

point, the inverter 7shuts down.

The recharge time required to restore the battery to its rated backup power varies

between 4 and 16 hours depending on the Comet model.

When the AC input power failure ends or power returns to within tolerances:

■ if the end of battery backup power was not reached, Comet returns to the

operating status described above (figure 19);

■ if the end of battery backup power was reached, the rectifier 2, the

charger 6and the inverter 7automatically start up (the inverter must be

manually started if the system is in manual start mode).

overloads on 5 kVA Comet S11 or S31

For a major temporary overload (greater than 1.5In):

The load is transferred to AC input power via the "static bypass" 3 for 5 seconds.

After that time, it is transferred back to the inverter.

If the overload persists, this sequence will be repeated 3 times in all before the

inverter is shut down and the supply of power to the load interrupted.

For a minor overload:

Minor overloads can be supplied by the inverter for a duration defined in figure 21

for an ambient temperature of less than 30°C. Above this temperature, a derating

coefficient k must be applied to the rated current and therefore to the overload

curve in figure 21:

■from 30°C to 35°C: k = 0.9,

■from 35°C to 40°C: k = 0.85,

■above 40°C: k = 0.8.

Example: an overload current I can be supplied by the inverter for 1 minute

under the following conditions:

■1.1 In < I < 1.3 In for an ambient temperature of 25°C,

■1.1 x 0.9In < I < 1.3 x 0.9In for an ambient temperature of 32°C,

■1.1 x 0.85In < I < 1.3 x 0.85In for an ambient temperature of 37°C,

■1.1 x 0.8In < I < 1.3 x 0.8In for an ambient temperature of 42°C.

When an overload occurs:

■the buzzer 17 sounds,

■the orange "fault" light 19 goes on,

■the inverter 7 shuts down at the end of its corresponding overload time,

■the load is supplied by AC input power via the "static bypass" 3 ,

■the green "load protected" light 21 goes off,

■the red "load not protected" light 18 goes on.

The load is supplied via the "static bypass" 3 for 5 seconds, after which it is

transferred back to the inverter. If the overload persists, the inverter shuts down

and the supply of power to the load is interrupted.

maintenance and servicing

Preventative maintenance for the Comet is limited to the strict minimum.

However, the list below indicates important procedures to ensure continuous and

correct operation.

Danger: high voltages are present in the Comet system. Any servicing requiring

removal of the protection covers may be undertaken only by qualified personnel

certified by MGE UPS SYSTEMS.

■ check the installation and operating conditions:

■■distance from wall,

■■ventilation inlet and outlet vents free,

■■operating temperature, particularly for the batteries;

■no faults signalled by the lights.

Consult the after-sales support department for further information concerning the

services presented below requiring special tools, in particular the "Soft Tunor"

software.

Battery status is monitored by Comet. When the orange "operation on battery"

light 20 flashes and fault number "12" is indicated on the diagnostics display 27,

the battery should be checked.

When the red "load not protected" light 18 flashes and fault number "15" is

indicated on the diagnostics display 27 , a battery fault is present.

To clear these alarms, press the "security" 26 and "fault reset" 25 buttons at

the same time.

Caution: clearing the alarms in this way disables the battery monitoring and

backup time calculation functions (Monitor Plus option); contact the after-

sales support department to check the condition of the battery and replace

it if necessary. The after-sales support technician will reactivate the battery

monitoring and backup time calculation functions.

The battery cells contain substances which are dangerous for the environment.

Following replacement, the after-sales support department forwards old batteries

to special organizations for recycling and disposal.

Installation of an emergency off function must be carried out in compliance with

applicable regulations. When an external emergency off function is activated, the

AC input to Comet must be cut to ensure protection of life and property.

However, this action does not cut the supply of power to the load protected by

Comet because the system continues to operate on battery power.

To power down the entire installation via an emergency off function, the action

must also turn off the following via a single device:

■ the battery circuit breaker 4;

■ the circuit breaker for the additional battery cabinet(s), if applicable;

■ and a circuit breaker placed downstream of the UPS, otherwise the UPS output

remains live for approximately 3 seconds after the emergency off function has

been activated.

This requires installation of an MX shunt trip.

■ check that the upstream circuit breaker on the low voltage switchboard is in "off"

position;

■ check that the input power switch 1and the battery circuit breaker 4are in

"off" position;

■ remove the connection cover panel 13 from the Comet;

■ supply the shunt trip coil with AC power across terminals 1 and 4;

■ terminals 2 and 3 may be used to supply (using a voltage identical to that of the

shunt trip) lights indicating the position of the battery circuit breaker 4(breaking

capacity of contacts is 1300VA);

■ once the connections are made, reposition the connection cover panel.

selection of cable cross-sections

The cross-section of cables depends on:

■ current levels (temperature rise);

■ permissible line voltage drop (3% for AC circuits, 1% for battery circuits);

■ installation (cable rack, troughs, etc.).

Consult the applicable standards to determine the minimum cross-sections for the

desired currents.

Each of the above parameters, for a given type of Comet, is important in

determining the minimum permissible cross-sections.

When confronted with several possibilities, always select the larger value. Cables

must be flexible type.

The currents indicated below are maximum values given for minimum voltages:
