Redundant DC Terminal Block Power Inputs
There are two pairs of power inputs for use with redundant power sources. You only
need to have one power input connected to run the switch.
Step 1: Connect the DC power cord to the plug-able terminal block on the switch, and
then plug it into a standard DC outlet.
Step 2: Disconnect the power cord if you want to shut down the switch.
Alarms for Power Failure
Step 1: There are two pins on the terminal block used for power failure detection. It
provides the normally closed output when the power source is active. Use this
as a dry contact application to send a signal for power failure detection.
*Warning signal disable for
following:
The relay contact closes if
Power1 and Power2 are
both failed but Power3 on.
The relay contact closes if
Power3 is failed but
Power1 and Power2 are
both on.
Special note:
The relay output is normal open position when there is no power to the switch.
Please do not connect any power source to this terminal to prevent shorting
your power supply.
