RINGS, WATCHES AND JEWELLERY SHOULD BE REMOVED AND ONLY INSULATED TOOLS SHOULD BE USED. A SOLDERING IRON SHOULD NOT BE USED UNLESS THE INPUT AND OUTPUT HAVE FIRST BEEN ISOLATED.

(3)THESE UNITS USE POSITIVE EARTH. CAREFULLY OBSERVE THE CORRECT POLARITY WHEN CONNECTING THE UNITS.

(4)LIVE WORKING MUST NOT BE CARRIED OUT ON THE UNITS UNLESS ABSOLUTELY NECESSARY. A CERTIFICATE OF LIVE WORKING MUST BE OBTAINED BY THE PERSONNEL INVOLVED BEFORE ANY LIVE WORKING IS COMMENCED.

(5)REFER TO MANUAL HANDLING, SECTION 8, BEFORE ATTEMPTING TO LIFT OR MOVE THE UNITS. Stage 1 - Unpacking

4Unpack the unit and check that the unit is present and undamaged and includes a handbook and factory completed test certificate.

Stage 2 - Input connections

5To connect the dc input cables to the unit, proceed as follows:

5.1Mount the unit on a suitable wall using the mounting hole on each corner.

5.2Ensure that the external power system intended for connection to the unit is switched off.

5.3Open the door, remove five screws and washers on the plastic plate and lift off the plate.

5.4Remove the circular plate from the bottom and feed the negative and auxiliary positive common input cables from the external power system into the unit.

5.5Connect the negative cable to either the internal negative input plate (for 15000218 and 15000248) or the external NEGATIVE IN busbar (for 15000264). Note that the unit does not require a positive common input cable.

5.6Connect the auxiliary positive common cable (to power the LVD PCA) to the AUX. terminal on TB1 (terminal 3).
