3.4.1 

Remote Override Switch

The 

Remote Override

 is a three-position switch used as a local override to the remote command system. The three 

modes are labeled 

EPO Only

, 

Off

, and 

Remote

. These are named from the perspective of having a remote control panel 

connected  to the system.

When there is a remote panel connected to the PDU:

• 

Remote

 (down position) is the normal operating mode. All outlets except the two utility outlets (the two highest 

numbered outlets) are subject to the remote panel On/Off/EPO controls (and, the internal software-controlled relays).

• 

Off

 (center position) causes an internal contactor to disengage power from all switched outlets. Utility outlets are not 

affected. The PDU will ignore the On/Off/EPO commands of the remote panel. Therefore, 

Off

 disconnects power to 

the switched outlets even if the main breaker is switched on, and even if the internal software-controlled relays are 

switched on.

• 

EPO Only 

(up position) causes the PDU to ignore the On/Off commands of the remote panel. However, the EPO 

signal is still allowed.

When there is not a remote control panel connected:

• 

EPO Only

 (up position) is the normal operating mode. Effectively, this is a Local Control mode.

• 

Off

 (center position) causes an internal contactor to disengage power from all switched outlets. Utility outlets are not 

affected. The PDU will ignore the On/Off/EPO commands of the remote panel. Therefore, 

Off

 disconnects power to
