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).
