Chapter 1 Install the Switch
4. Insert the exposed part of the positive wire into the connection labeled V
and the exposed part of the return wire into the connection labeled RT.
Make sure that you cannot see any wire lead. Only wire with insulation can
extend from the connector.
5. Use a ratcheting-torque screwdriver to torque the power and relay
connector captive screws above the installed wire leads to 0.23 N•m
(2.0 lb•in).
6. Connect the other end of the positive wire (the one connected to V) to the
positive terminal on the DC power source, and connect the other end of
the return wire (the one connected to RT) to the return terminal on the
DC power source.
You can use a second power source to provide redundant power. The alarm
relays on the switch can be used to warn you if one of the power supplies
fails. The switch operates properly with only one power source connected
at either Pwr A or Pwr B.
7. If you are installing the switch and are using a second power source, repeat
steps 2 … 6 with a second power and relay connector.
ATTENTION: If multiple power sources are used, do not exceed the
specified isolation voltage.
