PDU connections and power distribution basics
The Model 42000-PDU consists of a 24 VDC output to supply EMO circuitry with power. This supply also provides
24 VDC out through banana jacks. Additional outlets provided are two specially switched power outlets (factory
configuration: always on), and three strips of four switched outlets (off only with EMO condition). Control is through
a 25-pin D-sub connector.
WARNING
Properly lockout/tagout the system before beginning installation or
connection. Also, never power up the system until all connections and safety
grounds are installed. Make sure the main circuit breaker on the power
distribution unit is placed in the OFF position before making or breaking any
connections.
WARNING
Properly ground the 42000-PDU to avoid possible personal injury or death
caused by electric shock.
The connection schematic contained in Figure 4
provides power to the S500 cabinet fans. Figure 4 and Table 2
provide a detailed description of the available connections. Information on the EMO circuit's connection and
operation is also provided. Refer to Model 42000-PDU documentation for detailed information.
