1.0 INTRODUCTION
1.1 Summary of the manual
This handbook provides for the safe installation, startup and use of the EDP70 PLUS Uninterruptible Power
System (UPS). The Company recommends that the equipment be installed and regularly maintained by a
Chloride Authorized personnel.
DO: -read the User Handbook before operating the EDP70 PLUS UPS.
-keep a log of all incidents.
-protect the batteries from damage. Batteries leak acid; avoid contact with skin,
clothes or eyes.
DO NOT: -operate the control switches.
-operate the EDP70 PLUS UPS with any covers removed.
-obstruct the ventilation grilles.
1.2 Summary of the equipment
The EDP70 PLUS Uninterruptible Power System (UPS) totally isolates the load from voltage drops, spikes,
transients frequency variations in the utility supply.
In the event of failure or brownout of the AC utility supply, an internal audible alarm sounds and an LED on the
control panel illuminates, the EDP70 PLUS UPS will continue to provide safe, clean continuous power, without
interruption, from the battery, for a duration dependent on battery capacity and output load.
The audible alarm alerts the user to start a safe orderly shutdown of the load. When the AC utility supply returns to
normal, the EDP70 PLUS UPS automatically recharges the battery ready for any future power failure.
The microprocessor display panel provides access to very detailed information regarding the status of the supplies
and EDP70 PLUS UPS. Refer to current publication for detailed specification.
The block diagram, shows the main functional sub-assemblies of the EDP70 PLUS UPS. The AC three phase
utility supply is rectified to provide direct current, which maintains the battery in a fully charged state and also
supplies the inverter, which provides the three phase output via an electronic static switch.
Normally the supply of the reserve line is taken from the AC utility input, but special units, with a separate reserve
input supply, are available. This allows the inputs to be supplied from independent three phase sources.
Provided the reserve supply is within limits, the inverter will match the output frequency with the reserve supply
frequency. The inverter has its own internal crystal control to stabilize the output frequency if the reserve supply
frequency is out of limits. The electronic static switch switches the output from the inverter to the reserve supply,
without interruption, to meet any load current surges, or to supply the load if the battery is discharged during an AC
utility supply failure.
Maintenance and testing can be carried out on the EDP70 PLUS UPS without interrupting the output, by switching
the load from the reserve supply to the maintenance bypass circuit. This work should only be carried out by
Chloride-trained personnel.

The uninterruptible power system consists of the following:
1-RECTIFIER/INVERTER S1 = Equipment ON/OFF switch
2-BATTERY S2 = Equipment Reserve switch
3-BACKFEED PROTECTION S3 = Equipment By-pass switch
4-INVERTER STATIC SWITCH S4 = Equipment OUTPUT switch
5-RESERVE STATIC SWITCH (INVERTER OUTPUT switch for 50/80kVA only)
S5 = RESERVE OUTPUT switch for 50/80kVA only
1.4 Functions
RECTIFIER / BATTERY CHARGER
The rectifier/battery charger transforms the alternating current of the mains supply to direct voltage to maintain the
battery in a fully charged state and also supply the inverter.
BATTERY
The battery is an energy reserve that is used by the inverter and the load whenever the mains supply fails.
INVERTER
The inverter changes the direct voltage from the rectifier or from the battery into a three phase sinusoidal
alternating voltage for the external supply.
ELECTRONIC STATIC SWITCH
The function of the electronic static switch is to select one of the two sources of alternating voltage and to supply it
to the external load. The two sources of voltage supplied to the static switch are the output of the inverter and the
reserve supply. In normal working conditions, the static switch supplies the load from the inverter.
SWITCHES
The switches permits maintenance and repair of the UPS, without interrupting the supply to the load.

1.5 Operational modes
Figure 3 – Normal operation
During normal operation the load is supplied by the mains through the rectifier and inverter. The rectifier also
supplies the current for recharging and maintaining the battery in a fully charged state.
Figure 4 – Utility Supply failure
When the utility supply voltage is absent or outside the allowed tolerances, the battery supplies the inverter. This
will be indicated on the UPS front panel display and the Remote Alarm Unit (if fitted). The standby time available
depends both on the capacity of the battery and on the size of load. It is possible to extend autonomy by reducing
the output power by disconnecting non-important loads. In all cases, the alphanumerical display shows the residual
autonomy.

Figure 5 – Re-establishing the Utility Supply
When the utility supply returns within acceptable limits, the UPS returns automatically to normal operation mode as
previously described. The rectifier now starts to recharge the battery. However, until recharge has been
completed, any further mains failure will result in reduced standby times.
Figure 6 – Transferring the Load onto the Reserve Supply
Transfer onto the reserve line is caused by two conditions:
a) inverter stop
b) overload
In both instances the load is transferred onto the reserve without interruption. If the overload is temporary, the
system will re-transfer from reserve to inverter as soon as the it ceases. This allows for the initial start-up of loads
with high or excessive switch-on currents.

Recommended wire sizes
1) It is recommended that the external cables and protection be selected for the highest
rated unit of the model in use.
2) Reserve (or primary) input and output Neutral cable size should be greater than that of
the line cables in order to be able to supply non-linear loads having a Crest Factor of up to
3:1 (i.e. where neutral current = 1.7 x line current).
If non-linear loads are not to be supplied from the Installation, the Neutral can be of the same
size as the load cable.
3) Recommended AC input overcurrent protection represents 125% of nominal full load
current (continuous) plus the short duration input current (non-continuous) for battery re-
charging per NEC 220-10 b.
4) UPS output cables should be run in separate conduits from input cables.
5) Grounding conductors are sized per NEC 250-95.
6) Cable sizes are based upon NEC.
Recommended sizes only. Be sure to follow the codes which apply to your
installation.

4.4 Ventilation
UPS can work in a continuous environment within 18°F[-10°C] to 104°F [+40°C ] temperature range, although,
ideally the ambient temperature should be below 78°F [25°C].
The heat, dissipated by the UPS (indicated on figure 7), is extracted by internal fans and then dissipated into the
air.
The heat can be removed from the UPS room by a forced cooling ventilation system or, alternatively, an air
conditioning system.
The required air changes per hour will depend on the UPS rating and this heat loss and on the cooling air
temperature.
To calculate the required air flow for the dissipated power, the altitude and the cooling air temperature, the
following equation can be used:
•Pd
V= 2770 - - - - - - • e (0.125 h Tk / T0 )
Tr - Tk
with: V= air flow [mc/h]
Pd= total dissipated power [kW]
Tr= max. temperature allowed into the room [104°F = 40°C = 313°K]
Tk= Temperature of input cooling air
T0= 273 °K
h = altitude above the sea level [km]

5.4 Signal connections
a) Emergency Power Off
When the connection between terminals 1 and 2 is opened, the UPS will stop, and it will
automatically restart when the switch is closed. This allows a remote E.P.O. to be installed, in series
with the standard one installed inside the UPS. (See Para. 9.1)
Warning: To avoid unauthorized stopping, it is strongly recommended that some form of security switch be used..
b) Battery charge inhibited
By removing the link between terminals 3 and 4, the battery charge will be inhibited, and a warning
message will be displayed.
Possible uses of this could be one, or more, of the following:
•connect the above terminals to a contact which will be opened if there is Hydrogen within the
battery compartment(s).
In this way the cause of hydrogen generation will be stopped, and a warning about the operating
status of the system will be displayed.
•connect the above terminals to a contact which will be opened when the UPS is supplied by a
Generator (it should be an auxiliary contact of the Line <-> Generator changeover).
In this way it will be possible to limit the power supplied by the Generator to the only value
required to supply the critical loads, and not to charge the battery until the mains supply returns.
In this way it is possible to use a Generator having a power rating less than the maximum input
power of the UPS.
Also in this case a warning about the operating status of the system will be displayed.
c) Thermostick connector (50/80kVA only)
This connection provides the customer with remote control over the output transformer
Overtemperature Alarm (TCORE = 180°C).
NOTE: If more than one of the above applications (or similar) are installed, the contacts MUST be
connected in series.

8.0 MAINTENANCE BYPASS
The EDP70 PLUS UPS is equipped with Manual Maintenance Bypass systems. If a unit requires servicing, the
Manual Maintenance Bypass allows the load to be connected directly to the AC supply so that the unit may be
serviced in safety. The following instructions must be followed:
1. Ensure that ‘SYSTEM NORMAL’ is displayed on the LCD. (Note: If ‘SYSTEM NORMAL’ is not
displayed check that the inverter is not ‘OUT OF SYNC’, see section 10.7. Turning the inverter off
under this fault condition will interrupt the load supply.)
2. Turn off the inverter by pressing the inverter shutdown button for more than 2 seconds
3. Turn the Maintenance Bypass Switch (located behind front panel, see figure 14, 17 or 20) to ON.
4. Turn off the Primary Input, Reserve Input and UPS Output Switches, see figure 14, 17 or 20.
THE LOAD IS NOW SUPPLIED DIRECTLY FROM THE AC UTILITY SUPPLY AND IS NO LONGER
PROTECTED BY THE UPS
CAUTION: Some components in the UPS will retain a static voltage even after the switches have been
opened. Also, on the 50/80kVA ratings, the isolating transformer and the relative cooling
fans are still supplied from the Bypass.
To return to the normal operating mode, follow the above procedure in reverse.
Note: The EDP70 PLUS UPS must not be left operating with the Maintenance Bypass Switch in the ON
position.
9.0 SHUT-DOWN
1. Close down the load in an orderly manner.
2. Push the (inverter shutdown) button for more than 2 seconds.
3. Turn the main switch to OFF.
Note: If the electricity supply to the site is switched off outside normal working hours, the EDP70 PLUS should
be shut down each evening, by either using the shutdown procedure or wiring in the Emergency
Power Off (EPO) function, see figures 14, 17, 19 or 22 (depending on the UPS size).
This will prevent the battery from discharging.
If, on the other hand, the supply to the site is continuous, the EDP70 PLUS should be operated 24
hours a day.
9.1 Installing the EPO
To wire the EPO, open the link between terminal boards 1 and 2 and connect a signal switch: when the switch is
enabled, the inverter and rectifier will stop, the battery relay will be opened and the load will be de-energized
MI00/10056 rev.1--05/2001-- page 43
To ensure that the EPO functions correctly, the signal should remain active for a period > 400 msec.
page 44 -- MI00/10056 rev.1--05/2001
10.0 VISUAL AND AUDIBLE ALARMS
The EDP70 PLUS UPS is equipped with visual and audible alarms which indicate the status of the UPS to the
