start-up

preliminary checks

■check the settings of the protection devices:

■input power switch 1 in off (O) position,

■battery circuit breaker 4 in off (O) position,

■"manual bypass" 8 switch set to "NORMAL" position (see figure 18);

■check that nothing can block the ventilation system (air entry through the bottom and, where applicable, through the side vents);

■check that there is a minimum 100mm clearance at the back for ventilation;

■check that Comet no longer rests on its 4 wheels (lifting jacks in place);

■check that the load-circuit circuit breakers (where applicable) are in off (O) position.

powering up to Comet

Caution:

As soon as AC input power is supplied to Comet (upstream circuit breaker on the low voltage switchboard in "on" position), the load is supplied via the "static bypass" 3 . No indications are given on the control panel.
