Types of remote
switches
supported The RPO supports two types of remote switches:
• A contact closure switch toggles between an open and
closed circuit.
• A voltage input switch applies and removes a voltage
signal.
Set the DIP
switches On the UPS side of the Remote Power-Off Device, set the DIP
switches labeled CONFIGURATION.
Power-off condition: DIP switches #1 and #2. Use these DIP
switches to configure the power-off condition for the RPO
according to the type of remote switch it is using.
If the positions of DIP switch #1 and DIP switch #2 are both up
or both down, the configuration is invalid.
To connect the remote switch, see “Remote
switch: requirements and pin assignment” on
page 16.
