3.2.3Emergency Stop

If an external Emergency Stop facility is required it is connected to terminals 5 & 6 of the Auxiliary Terminal Block (X4) and connect the ‘normally closed’ remote stop switch between these two terminals using shielded cable. If this facility is not used then terminals 5 & 6 must be linked-out as shown in Figure 3-3.

Note: The Emergency Stop action within the UPS shuts down the rectifier, inverter and static bypass and trips the battery circuit breaker. It does not however internally disconnect the input mains supply. If required, this additional action can be facilitated by feeding the UPS input via a circuit breaker which can be tripped by a second contact of the Emergency Stop switch.

Note: Terminals 11 and 12 of the Auxiliary Terminal Block (X4) are connected to a normally closed contact of the UPS Display Panel Emergency Stop button and go open circuit when the button is pressed. This output can be used as part of a wider Emergency Stop system to initiate an external action (such as tripping an external supply breaker)

3.2.4Back Feed Protection

Using an auxiliary terminal (pins 9-10 of connector X4) the UPS provides a normally open contact to be used for opening of an external circuit protection device, to protect the operator against back feed of energy resulting from a short-circuit fault of the Bypass line SCRs. This auxiliary contact can be used, for example, in series with an external low voltage source, in order to supply the trip coil of an automatic circuit breaking device, located upstream of the UPS Bypass mains input. In the vent of energy being backfeed the auxiliary circuit will activate closing the normally open contact and as a result opening of the external circuit-breaking device; the UPS is disconnected from the Bypass mains supply. The electrical characteristics of the auxiliary contact are 50V (a.c. or d.c.) @ 1 Amp.
