Electrical Installation
It is recommended that conduit be installed onto the ¾” NPT connection on the electronics housing. A seal drain fitting
should be used to prevent moisture from entering the switch. In high humidity areas, use a breather drain to minimize
moisture intrusion
All wiring, conduit, and fittings must conform to local electrical codes for the location selected. If the transmitter is to be
used in a Hazardous Area, the applicable sections of the National Electric Code must be followed as well.
WIRING CONNECTIONS
Before starting installation procedures in hazardous areas, insure that all power sources have been turned off and locked
out. “Live” electrical circuits can ignite flammable gasses and dusts.
1. Remove the cover from the instrument enclosure.
2. Loosen the (2) screws holding the electronics module in place. These are spring-loaded captive screws. They
will pop-up when loosened sufficiently. Remove the electronics module from the instrument enclosure.
3. Hold the module firmly around the transformer and pull it out of the enclosure. No tools are necessary to remove
the module.
