HP UPS Extended Runtime Module - Manual (Page 21)

Installation 21
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. HP
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.
• Use tie wraps and tie wrap blocks to secure the wires tightly to the rack and the rear of the UPS.
For more information about the REPO port, see "REPO port (on page 11 )" .
For information about verifying the REPO connection, see "Verifying the REPO port connection (on page
31 )" .
