E.2.1 Go Switches
Remove the access plate by unscrewing the four slotted screws
on the bottom of the unit. Thread the cable through the ½” NPT
fitting and connect to the appropriate Normally Open (NO), Nor-
mally Closed (NC) and Common (C) screw terminals. The cable
should be grounded in accordance with Local and National Elec-
trical Code. Make sure that the gasket is in place and tightly seal
the cavity.

Remove the cover by unscrewing. Take care to keep threads clean
and free from damage. Thread the cable through the ½” NPT
fitting and make connections directly to the microswitches. The
cable should be grounded in accordance with Local and National
Electrical Code. Make sure that the O-ring gasket is in place and
tightly seal the cavity.

repositioned. Make sure that the O-ring gasket is in place and
tightly seal the cavity.
