NOTE

All auxiliary cables of terminal must be double-insulated. Wire should be 20-16AWG stranded for maximum runs between 82 and 164 feet (25-50m), respectively.

2.3.5EPO Input—Optional

Firmware Before M200

The UPS has an Emergency Power Off (EPO) function that operates by a button on the control panel or by a remote contact provided by the user. The EPO button is under a hinged, clear plastic shield.

The X2 slot, shown in Figure 10, is the remote EPO input interface. It is active when shorted from EPO-L to EPO-H.

If an external Emergency Stop facility is required, it is connected terminals EPO-L to EPO-H of the auxiliary terminal block (X2). It also is connected to the Normally Open remote stop switch between these two terminals using shielded cable (see Figure 10 and Table 5). If this function is not used, terminals EPO-L to EPO-H must be opened.

NOTE

The Emergency Stop action within the UPS shuts down the rectifier, inverter and static bypass. It does not internally disconnect the input power supply.

To disconnect ALL power to the UPS, open the upstream feeder breaker(s) when the remote EPO is activated.
