DPOE™ Power System User Manual Part Number: PN380C

INSTALLATION
CAUTION:
Observe all local and national electrical, environmental, and workplace codes.
Each chassis should be fed from a dedicated AC branch circuit of a TN or IT power system.
CAUTION:
The plug ends on the power cords used for the AC connections are considered to
be the primary disconnect means. Reasonable access must be given to the plug
and receptacle area. The receptacle must be fed with a breaker or fuse according
to Table 4: Recommended AC Circuit Breaker and Wire Sizes
.
Use single hole, Underwriters Laboratory (U.L.) listed lugs for the bulk DC connection to prevent lug
rotation and inadvertent contact with other circuits. Terminal strip connections use compression screws.
Class 1 wire is recommended for all DC connections. Minimum wire sizes for protected and unprotected
circuits are shown in Table 5: Minimum Recommended DC AWG for 90°C Cabling for Unprotected
Outputs , respectively. In practice, loop voltage drop considerations will usually dictate larger than
minimum safe wire size.
For connection and mounting torque requirements see Table 6: Recommended Torque Settings
.
PANDUIT Corp. does not recommend shipping the chassis with the rectifiers installed. Rectifiers should
be shipped in their separate boxes.
