Connection procedure

WARNING! The supply modules are heavy and have a high centre of gravity. Be careful when
manoeuvring the modules.
Removal of module:
(1) Turn the supply (rectifier) module switch-disconnector handle to open
position.
(2) Release the door handle and open the supply unit door.
(3) Remove the fastening screws at the top of the module.
(3b) Units with marine construction (+C121) only: Remove fan (see page
107 for instructions) and the two fastening screws at the rear bottom of the
module frame.
(4) Loosen the connector locking screw (hexagonal socket head).
(5) Place the module pull-out ramp against the cabinet base. Make sure
the ramp is secured to the cabinet frame.
(6) Pull the module carefully out of the cabinet along the ramp.
Remove the plastic insulators covering the input power terminals.
Lead the cables into the inside of the cabinet. Make the 360° earthing
arrangement at the cable entries as shown below.
Connect the cables as follows:
• Twist the cable shields to bundles and connect to cabinet PE (ground)
busbar. Connect the separate ground conductors/cables to cabinet PE
(ground) busbar.
• Connect the phase conductors to the input power terminals (U1.1 ...).
Depending on the cable size, use cable lugs or dual-cable screw lug
connectors. For details on the terminals and tightening torques, see
Technical data
the dual-cable screw lug connector
Refit the plastic insulators onto the input power terminals.
Push the module back in – mind your fingers – and tighten the fastening screws. Tighten the connector
locking screw to 4 Nm (3 lbf.ft). Please note that the module can only mate with the quick connector when
the switch-disconnector is in open position.
Remove the module pull-out ramp and close the cubicle doors.
