NOTE
Electrical equipment should be installed, operated, serviced,
and maintained only by qualied personnel. No
responsibility is assumed by Schneider Electric for any
consequences arising out of the use of this material.
A qualied person is one who has skills and knowledge
related to the construction, installation, and operation of
electrical equipment and has received safety training to
recognize and avoid the hazards involved.
NOTICE
HAZARD OF TERMINAL DAMAGE OR INCORRECT POWER SUPPLY
bUse appropriate tightening torques for tightening connector screws (tightening torque values provided in this document).
bThe LV150 module must be powered by a power supply of the SELV/PELV type (e.g. the PS50 module).

Parameters setup
Installation of the LV150 module requires no parameters setup. This is performed during the
commissioning/conguration stages
.
Refer to the User Manual and the Quick Start manual for any further information.
Identication
The serial number of the LV150 is formed as follows: Year - Week - Work order, e.g. 16340265 (265th
product manufactured, week 34 of the year 2016)
Grounding
The LV150 module must be connected to the ground:
bEither via the mounting DIN rail. The DIN rail helps ensure electrical continuity (preferably use a DIN rail in
304L stainless steel to withstand the climatic conditions).
bEither by means of an eye lug and a M4 screw (max. Length 10 mm), screwed in the threaded hole at the
back of the LV150 housing (see diagram below). Use a green/yellow wire of length 300 mm maximum (11.81
in) and 4 mm² section (11 AWG) for the connection between the eye lug and the ground.
Operation
Once the LV150 has been powered up, some indicator lamps on the front panel may be lit to indicate certain
operating states.
These indications are summarized in the table below:
Part Description of indications and actions
LV150 states:
1.1 LV150 operating, communication status with the HU250
1.2
Equipment status (potential software issue, potential hardware issue, potential
conguration issue).

Orange: power on or o on at least one of the phases
Note: The indications in bold letters correspond to normal operation (rst power up
without existence of a potential issue indication).The voltage presence states cannot
be determined for normal operation, because that depends on the state of the
network.

Installing CTs
The setup concerns a 3 split-core phase CTs or 3 split-core phase CTs + neutral CT.
The cables must be centered as far as possible inside the toroid to help ensure the accuracy of the
measurement.
NOTICE
HAZARD OF INCORRECT CURRENT MEASUREMENT
bPay attention to the mounting direction of the CTs. It must not have an impact on the current measurement.
Failure to follow these instructions can result in equipment damage.

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
bWear your personal protective equipment (PPE) and comply with the safe electrical work practices. See NFPA 70E in
the USA or applicable local standards.
bOnly qualied person should install this equipment. Such work should be performed only after reading this entire set of
instructions.
bSwitch o the electric power supply of the LV150 and of all the devices to which the LV150 is connected before any
handling or replacement operation.
bAlways use a properly rated voltage sensing device to conrm that all power is o.
bDo not connect VT adapter directly to the LV sensors. Always use fuse and disconnect switch (maximum voltage
allowable on the VT adapter inputs : 10 VAC).
bNever short the secondary of a Voltage Transformer (VT).
Failure to follow these instructions will result in death or serious injury.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
bThe current sensors used for measuring must be 1 A or 5 A secondary with security factor limiting the current to 100 A
secondary -1 s (according to standard 61869-2).
bThe toroids must be short-circuited at the secondary when they are disconnected from the LV150 (eg during a
maintenance operation). To do this, use a shorting block.
bThe low-voltage insulation of the Easergy CTs means they can only be used on insulated cables.
bAlways use grounded external CTs for current inputs.
bEnsure the LV Network is turned o before to install the CTs on the LV cable and making the CTs connections to the
LV150.
Failure to follow these instructions will result in death or serious injury.

bThe DIN rail on which the LV150 is installed (if the LV150 is grounded by the DIN rail) must be grounded and of metallic
type and must comply with electrical continuity in all climatic conditions.
bIf the LV150 is installed on a PS50 power supply module, the grounding of the module is done via the PS50's DIN rail,
which must be grounded via a dedicated terminal near the PS50 power input connector. Refer to the Installation Guide of
the PS50 power supply.
