42000-PDU connection descriptions
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 the PDU box. Connect the PDU box to the EMO box
with the supplied DB-25 male-to-female cable.
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.
