DPOE™ Power System User Manual Part Number: PN380C
The DPOE™ Power System Chassis allows a bulk DC connection as shown in Figure 12: Chassis (Rear
View) - DC Connections. The bulk DC connection may be optionally used to ensure continued power to
the connected DP
OE™ Power Patch Panels and the PD connected to the panels in the event of a power
failure. This connection may be used as a battery input or as an unfused bulk output. The bulk DC
connection requires properly crimped terminal lugs (1/4” single hole lug with a max tongue width of 0.63”
or less). Terminal lugs (such as PANDUIT part # LCA4-14-L for use with #3 or #4 AWG stranded wire or
#2 AWG solid wire) and crimping tools (such as the PANDUIT part #s CT-1550, CT-1551, CT-1570, or
CT-1700) are available from PANDUIT Corp. The bulk output terminals feature a break-off plastic piece to
prevent inadvertent contact with the terminals. If using the bulk DC output feature, carefully break off each
plastic tab before securing the terminal lugs.
Size wires based on the total rectifier capacity and choose conductor size according to Table 5:
Minimum Recommended DC AWG for 90°C Cabling for Unprotected Outputs
. For battery or bulk
DC connections, place lug on the corresponding positive and negative studs, and secure the connections
with the included nuts.
