connection of power cables (figures 10 to 14)

Make sure the unit is powered down and disconnected from all input power before making connections to the terminal blocks at the front or back of the cubicle (depending on the type of Comet).

For protection of life and property, earth wires should always be connected first.

For Comet 31 series or Comet 33 series devices, the Mains power supply must be with a neutral cable.

For Comet 33 series, the neutral may be reconstituted by a complete insulation transformer option (a transformer with a triple-point structure).

Neutral system: identical upstream and downstream neutral systems (no galvanic isolation). Comet can be used with all types of neutral systems, on the condition that standard practices be respected.

■check that AC input power circuit breaker, installed upstream on the low voltage switchboard, is in off (O) position;

■check that the input power switch 1 and the battery circuit breaker 4 are in off (O) position.

Connection sequence for 5 kVA Comet:

■open the protective cover 44 (secured by 2 screws) and the connection cover panel 13 (secured by 6 screws);

■strip the duct of the AC input power and load cables over a length of 7 cm;

■strip each wire over a length of 1 cm;

■insert the cables of the AC input power and load through the bushings of the connection cover panel;

■connect the cables of the AC input power to "Mains 1" XR1 terminal block in the order shown on the label;

■connect the load cables to the "load" XR2 terminal block in the order shown on the label;

■connect the various options as shown in the relevant section for each one in this manual;

■when the cables have been connected, the duct of each cable must be tightened by a binding band against the horizontal binding bar placed beneath the terminal block in order to protect the conductors from tensile loads;

■put back the connection cover panel 13 and the protective cover 44 .
