1.6 Remote Emergency Power off

A Remote Emergency Power Off may be connected to the system. The connection terminals are M4 Pin 5 and Pin 6, using a nor- mally-open, voltage-free contact as a pushbutton.(See FIG. 1.6.1. and FIG 1.6.2.)

FIG. 1.6.1 Connection of Remote EPO with N.C. contact FIG. 1.6.2 Connection of Remote EPO with N.O. contact

Note 1: The cable used must be twisted pair, with a total shield. This shield must be grounded at one end (the cabinet of the UPS may be used).

Note 2: For Hot-Standby or parallel systems, it is sufficient to feed one contact into one unit only, however they may be connected in parallel at M4 (of IBYBP-CP) Pin5 and Pin 6 for all units (N/O) only or series for (N/C).

Note 3: To completely isolate the UPS system from all voltage with the emergency power off (EPO), it is necessary to install trippable circuit breaker on the input supply (to terminals 1-L1, 1-L2, 1-L3 and 4-L1, 4-L2, 4-L3 and 4-N if installed).

The trip coil is then connected to the terminal M1 on the CPU/NCP pcb located inside the front door of the cabinet. A normally open or normally closed voltage-free contact is available.

Note 4: The N.C. contact can only be used for IBYBP-CP motherboards in rev. 0A and following.
