emergency off

shunt trip connection

Installation of an emergency off function must be carried out in compliance with applicable regulations. When an external emergency off function is activated, the AC input to Comet must be cut to ensure protection of life and property. However, this action does not cut the supply of power to the load protected by Comet because the system continues to operate on battery power.

To power down the entire installation via an emergency off function, the action must also turn off the following via a single device:

■the battery circuit breaker 4 ;

■the circuit breaker for the additional battery cabinet(s), if applicable;

■and a circuit breaker placed downstream of the UPS, otherwise the UPS output remains live for approximately 3 seconds after the emergency off function has been activated.

This requires installation of an MX shunt trip.

■check that the upstream circuit breaker on the low voltage switchboard is in "off" position;

■check that the input power switch 1 and the battery circuit breaker 4 are in "off" position;

■remove the connection cover panel 13 from the Comet;

■supply the shunt trip coil with AC power across terminals 1 and 4;

■terminals 2 and 3 may be used to supply (using a voltage identical to that of the

shunt trip) lights indicating the position of the battery circuit breaker 4 (breaking capacity of contacts is 1300VA);

■once the connections are made, reposition the connection cover panel.
