Connection procedure

WARNING! Read and follow the instructions given in Safety instructions. Ignoring the instructions
can cause physical injury or death, or damage to the equipment.
WARNING! The supply modules are heavy and have a high center of gravity. Be careful when
manoeuvring the modules. To minimize the danger of toppling over, keep the support legs of the
modules extended whenever manoeuvring the modules outside the cabinet.
Extract each inverter module from the cubicle as follows:
(1) Open the door of the inverter module cubicle.
(2) Remove the shroud covering the upper part of the cubicle.
(3) Open the transparent cover on the front of the inverter module and disconnect the fibre optic cables.
Move the cables aside.
(4) Remove the L-shaped DC busbars on top of the module.
(5) Disconnect the terminal block (X50) next to the DC busbars.
(6) Remove the two module fastening screws (6a) at the top. At the base of the module, loosen the two
fastening screws (6b) but leave them in place; lift the bracket (6c) into the up position.
(7) Insert the module pull-out ramp under the two screws at the base of the module and tighten.
(8) Pull the module carefully out of the cubicle along the ramp. Make sure the wires do not catch.
(9) Extend the support legs of the module. Keep the legs extended until the module is about to be inserted
back into the cubicle.
