Installing the Contactor
1. Verify that the contactor is suitable for the area where it is to be
installed.
2. Check the line voltage and the heat-tracing load to ensure that
the contactor ratings are not exceeded.
3. Mount the enclosure in a position that prevents condensation from
draining into the enclosure from the connecting conduit
(see diagram at right).
