2. Installation

Fitting the protection cover for the auxiliary interconnection cables

The protection cover supplied with the parallel connected UPS units protects the user against direct contact with voltages

other than SELVs and ensures the auxiliary interconnection cables are maintained in position.

2.13 Connection of general shutdown or emergency power off (EPO) terminal

block

Note. Tie down the cables as indicated in the diagram in section 2.10.

1 - Remove the wire from terminal block (7).

2 - Connect the general shutdown NC contact to terminals 1 and 2 (SELV).

3 - Tie the cable down as illustrated in section 2.10.

Caution.

In the UPS, pressing the general shutdown button causes UPS shutdown and opening of the battery circuit breaker

(with opening of the bypass static switch depending on personalisation settings) .

The Emergency Power Off (EPO) notion is applicable to installations where pressing the button also causes the

upstream Normal AC source and Bypass AC source circuit-breakers to open.

In parallel configurations, there must be a single general shutdown button with a separate contact for each UPS unit.
