Connecting the USB communications port
NOTE: This port is only used for firmware upgrades. To
update the UPS firmware, see the Hewlett Packard
Enterprise website
(http://www.hpe.com/info/rackandpower).
Connecting the REPO port
WARNING: The pins on the REPO port are polarity
sensitive. Be sure to verify polarity while connecting the
REPO port.
WARNING: To meet the requirements stated in NEC
(NFPA 70) Articles 645-10 and 645-11, a UPS installed
in a computer equipment room must be connected to a
REPO circuit.
IMPORTANT: The remote switch must be in the Off
(open) position to enable power to the output
receptacles.
NOTE: Wire the connector block using stranded,
nonshielded wire (AWG #22 - #18, or equivalent).
Separate wire pairs are attached to a single, normally-open contact
in a parallel connection. Hewlett Packard Enterprise recommends
using different colors for the positive and negative wires.
If a connector becomes disconnected and is reconnected with
reversed polarity, a REPO is initiated. To avoid REPO port
disconnect:
•
Minimize wire strain while connecting the REPO port.
•
Avoid allowing the wires to hang in the rear of the UPS.
