APC 6000 Connection of auxiliary circuits on the remote relay board, XR1 XR2 XR3 XR4

Installation (cont.)

Connection of "Media Contacts 9" standard auxiliary circuits (figure 16)

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

◗recommended cable cross-section: 1 mm2 (use a shielded cable to connect the battery cell);

◗the male connectors that fit the female connectors on the board (XR1 to XR4) 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.
