6.2.12 Wiring
An opening in the base of the UPS is for passing the cables through and there are also some fixing points for the cables.
It is essential to secure the cables firmly after they have been connected to the equipment.
6.2.13 Emergency Power Off (Remote E.P.O.)
In accordance with the standards, the UPS is fitted with an emergency device arranged to use a normally closed external
contact that can be opened to activate the emergency machine power off.
The E.P.O. terminals are in the UPS's rear panel on pins 3 and 4 of the 6-pole Combicon connector installed on all contact
interfaces (see 3.5.2).
If there is more than one contact interface, connect the E.P.O terminals on each contact interface as follows:
1. connect the E.P.O. terminals of all the contact interfaces in parallel (pin 3 with pin 3, pin 4 with pin 4).
2. close the parallel created on the n.c. contact of the emergency power off device.
To connect the emergency-power-off device correctly please follow these instructions:
- use a cable with double insulation, no more than 10 metres in length.
- check that the switch used is galvanically insulated.
Electrical specifications of the E.P.O. interface:
- Voltage between terminals 3 and 4 (6P Combicon) with open circuit = 12Vdc.
- Current between terminals 3 and 4 (6P Combicon) with closed circuit = 5mA.
