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, an RPO is initiated. To
avoid RPO port disconnect:
• Minimize wire strain while connecting the RPO 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 RPO port, see
.
Connecting the ground bonding cable
The ground bonding screw is provided as an attachment point for conductors. Use a ground bonding
cable if the rack contains any conductors for the purpose of functional grounding or bonding of
ungrounded metal parts.
