Connect an XR Battery Enclosure to a running UPS
Warning: Before connecting an XR battery enclosure, ALL safety instructions in the
Safety Sheet (990-3620) must be read, understood and followed. Failure to do so could
result in equipment damage, serious injury, or death.
Note: This procedure describes how to connect an XR battery enclosure to a UPS running in
normal operation.
Note: A maximum of two battery enclosures can be connected to the UPS (one XR Battery
enclosure with a circuit breaker plus one enclosure without a circuit breaker) by a batch cable
between the UPS and the circuit breaker in the battery enclosure.
Note: Before carrying out the below procedure, make sure that the UPS is running in normal
operation with no internal UPS faults displayed. In normal operation all breakers must be in
the ON (closed) position except for the maintenance bypass breaker which must be in the
OFF (opened) position.
1. Turn the UPS into maintenance bypass operation:
a. Turn the static bypass breaker (QM2) to the ON (closed) position.
b. Turn the maintenance bypass breaker (Q3BP) to the ON (closed) position.
c. Turn the static bypass breaker (QM2) to the OFF (opened) position.
d. Turn the output breaker (QOP) to the OFF (opened) position.
2. Isolate the batteries by turning the UPS battery breaker (QB) (and the existing XR battery
breaker (QFB), if present) to the OFF (opened) position.
3. Remove all internal batteries in the UPS enclosure.
4. Prepare for cables. See “Prepare for Cables” on page 3.
5. Install the batteries. See “Battery enclosure with pre-installed batteries” on page 4 or “Battery
enclosure without pre-installed batteries” on page 5.
6. Connect the communication cables between the UPS and the XR. See “Connect Communication
Cables between the UPS and Battery Enclosure” on page 7.
7. Connect the XR Battery enclosure according to the relevant, electrical diagram under
“Appendix” on page 16, and according to the chapter “Connect the Battery Cables between the
UPS and Battery Enclosure” on page 8.
8. Verify the battery wiring as described under “Battery enclosure with pre-installed batteries” on
page 4 or “Battery enclosure without pre-installed batteries” on page 5
