powering down

It is recommended not to power down Comet for long periods because the battery should remained charged. However, to carry out a power down, proceed as follows:

■shutdown the inverter 7 ;

■ put the battery circuit breaker 4

in "off" position;

■ turn off the input power switch

1 ;

■all the indicating lights on the control panel go off.

Caution:

The load is still supplied by AC input power via the "static bypass" 3 ;

■put the upstream circuit breaker(s) on the low voltage switchboard in "off" position.
