2.0 ELECTRICAL CONNECTIONS
2.1 Connecting the Rack PDU DC Input
The Rack PDU’s input is designed to be fed from a 200A (max) breaker or fuse using the factory sup-
plied and connected DC input cable assembly and the customer connected input quick connect kits.
See Figure 3.
Figure 3 DC Input Connections
2.2 Connecting the Rack PDU’s DC Output to Customer Equipment
The Rack PDU’s output circuit breakers are connected to customer equipment via the separately
ordered output cable assemblies. A ground lead is also supplied with each output cable. Each ground
lead is terminated with a connector on one end (which mates with a connector on a ground wire fac-
tory connected to the "Ground Lead Bracket") and left unterminated on the other end. See Figure 4.
