DM105357.eps HAZARD OF TERMINAL DAMAGE OR INCORRECT POWER SUPPLY Failure to follow these instructions can result in equipment damage. Click! Installing the LV150 module on DIN rail Installing the LV150 module on a PS50 enclosure Installing CTs DANGER 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. HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH DM105366.eps bb Wear your personal protective equipment (PPE) and comply with the safe electrical work practices. See NFPA 70E in the USA or applicable local standards. bb Only qualified person should install this equipment. Such work should be performed only after reading this entire set of instructions. bb Switch off the electric power supply of the LV150 and of all the devices to which the LV150 is connected before any handling or replacement operation. bb Always use a properly rated voltage sensing device to confirm that all power is off. bb Do 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). bb Never short the secondary of a Voltage Transformer (VT). Failure to follow these instructions will result in death or serious injury. NOTICE bb Pay 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. DANGER HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH bb The 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). bb The 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. bb The low-voltage insulation of the Easergy CTs means they can only be used on insulated cables. bb Always use grounded external CTs for current inputs. bb Ensure the LV Network is turned off 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.

This is performed during the commissioning/configuration stages. Refer to the User Manual and the Quick Start manual for any further information. 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) S1 S1 The LV150 includes two connectors to connect the power supply. These two connectors are connected together internally in the LV150. Having two power supply connections can facilitate connection between the modules. No strapping is necessary. Connect the LV150 as shown in the following diagram in order to have the benefit related to power supply loopback. Identification N L3 L2 L1 S1 Power supply DM105361.eps HAZARD OF INCORRECT CURRENT MEASUREMENT S2 Com I 4 Grounding The LV150 module must be connected to the ground: bb Either 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). bb Either 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. Com N 5 S2 Eye lug N 6 M4 screw Ground connection terminal DM105373.ai Connector Current inputs 3 NOTICE HAZARD OF INCORRECT CURRENT MEASUREMENTS bb The 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. bb If 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. Failure to follow these instructions can result in equipment damage. Operation These indications are summarized in the table below: Part 1.1 1.2 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 configuration issue).
