Wiring
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. All wiring, conduit, and electrical fittings must conform to
local electrical codes for the location selected. If the switch is to be used in a Hazardous Area, the applicable codes of the
National Electrical Code must be followed as well.
1. Connect power wiring
a. AC – Hot (L2), Neutral (L2), and Ground (G)
b. DC – Positive (L1), Negative (G)
2. Connect relay wiring (see diagram)
3. Connect Manual Self-Test terminals to a remote pushbutton (maximum distance 30 feet).
4. Adjust failsafe jumper
a. HLFS – top (2) pins
b. LLFS – bottom (2) pins
