APC 6000 installation manual Acpz board of the Static Switch Cubicle, XR8 XR9 XR5 XR6 XR7

Installation (cont.)

Connection of "Media Contacts 15" additional auxiliary circuits (option) (figure 22)

The additional auxiliary circuits of the rectifier-inverter and Static Switch Cubicles are connected to additional remote relay board by means of the 4 connectors (see location of this board in the figures of the "connection of power circuits" section).

ACPZ board of the Static Switch Cubicle

◗recommended cable cross-section: 1 mm2;

◗the male connectors that fit the female connectors on the board (XR5 to XR9) are supplied;

◗the contacts are volt-free and are shown in the diagram under the following conditions: UPS on, contact at rest;

◗contact breaking capacity: 250V, 5A.

Note:

In a parallel-connected UPS installation the "load" and "mains 2" signals are provided by the Static Switch Cubicle.
