onto its gasket. Tighten the unit another 1/8 to 1/4
turn. Tighten the setscrew.
5. Reinstall the guard, where applicable, and secure using
the three supplied screws.
6. After the unit is assembled, apply power and make
sure the unit functions properly.
WARNING
To reduce the risk of ignition of hazardous atmo-
spheres and shock, keep assembly tightly closed
when circuits are energized.
To reduce the risk of ignition of hazardous atmo-
spheres and shock, disconnect from the supply and
circuit and allow five (5) minutes for stored energy to
dissipate before disassembling the unit.
