The following table provides a detailed description of the available connections in the 42000-PDU.
Information about the EMO circuit connections and operation is also in the table.
Depending on how many instruments you have in your system, you may have two power distribution
units (PDUs).
42000-PDU connection descriptions (for each PDU)
Connection
Description
Specially switched
outlets
Two power outlets on the power distribution unit (PDU) rear panel.
WARNING:
Severe personal injury or death due to electric shock or electrocution
may result if power is not removed before working inside the cabinet. Do not use
power outlets for accessories (for example, a soldering iron or drill). Use for
instruments that do not have hazardous voltages and do not need to have power
removed through the EMO circuit (for example, a computer). In the factory default
configuration, these outlets have dedicated power and will remain live even if
power is removed through the EMO circuit.
The specific configuration is marked on the PDU rear panel.

To PDU box DB-25
cable connector
Connector providing control of both PDU boxes. Using the supplied S510-360B
cable assembly, connect one of the female ends of the assembly to the PDU box
at the front of the cabinet, then connect the other female end of the assembly to
the EMO box. Connect the male end of the assembly to the other PDU at the back
of the cabinet. Using the S510-360B cable allows you to control power to both of
the PDUs through a single EMO switch.
Switched outlets
Twelve power outlets on the PDU rear panel. Do not use power outlets for
accessories (for example, soldering iron or drill). Use for equipment with hazardous
voltages that need to be removed with the EMO circuitry.
*
Ground connection
(optional)
Connect to a quality ground within your facility with 18 AWG wire.
External fan connection Connector providing 24 VDC to cabinet fans.
External EMO/shorting
plug connection
DB-25 connector providing connection to external EMO devices. Make sure the
shorting plug is installed if the system is not configured for external EMO.
24 VDC (
–) banana plug Banana plug providing 24 VDC (–) power connection.
24 VDC (+) banana
plug
Banana plug providing 24 VDC (+) power connection.
