EPO switch.

Note

Always follow the pin connection procedures from the top and work down: J106 (8-1), J108 (1-6).

Note

EPO (Emergency Power Off) switch wiring – pin connections J108 (for EPO wiring options)

Connect the EPO cable, using one of the following 4 wiring configurations:

Pins 1 to 4 are for battery measurement (only applicable to APC XR Battery Enclosures).

Pins 5 and 6 are for external maintenance bypass Q3 (auxiliary switch N/C type).

When Q3 is closed, signals are fed back to the UPS controller.

Pins 7 and 8 are for external charge control. When 7 and 8 are closed, the UPS charges batteries with a pre-defined percentage (0-25- 50-75-100%) of the maximum charging power. To be used in generator applications, or if special codes requires control of charging. When Q3 is closed, signals are fed back to the UPS controller.
