Worldwide Power Requirements - HP 204451-002 - UPS T2200 XR Best Practices Manual

7. R12000/3 and the NC REPO connector
This UPS has two kinds of REPO (remote emergency power off) options, NO (normally open) and NC
(normally closed). The NC REPO connector must be installed for the UPS to function properly. Not
installing the NC REPO is equivalent of a REPO signal being sent to the UPS. Please refer to the users
guide detailed installation instructions.
8. R12000/3 and A-B-C clockwise phase rotation
The HP three phase UPS require A-B-C clockwise phase rotation for the input wiring. The unit detects
and reports this Phase Rotation Error if condition exists on initial start up. To resolve this condition, the
electrician needs to swap any two input feed conductors. Ideally, the electrician should validate phase
rotation on install using the metering device specific for this purpose. It would be recommended that the
electrician be on call (or on site) at the time of startup to make the correction if required.
