MounttheOSW-U-0721-MVinthejunctionbox.
CAUTION: Before installing or performing any service on a Greengate system, the power MUST be turned OFF at
the branch circuit breaker. According to NEC 240-83(d), if the branch circuit breaker is used as the main switch
for a fluorescent lighting circuit, the circuit breaker should be marked “SWD.” All installations should be in
compliance with the National Electric Code and all state and local codes.
NOTE REGARDING COMPACT FLUORESCENT LAMPS: The life of some compact fluorescent lamps (CFLs) is
shortened by frequent automatic or manual switching. Check with CFL and ballast manufacturer to determine the
effects of cycling.
CAUTION: Model OSW-U-0721-MV is for use with either 120 VAC or 277 VAC only. For other voltages refer to
product spec sheet. Do not wire to control receptacle circuits.

4.Connecttheblackwiretothehotlead.
Note: Connectionsarepolaritysensitive.
CAUTION: If a room is wired for two circuits using two separate hot leads, it is very important to connect only one
circuit to the OSW-U-0721-MV. Split one circuit into two switch legs and cap the unused hot lead inside the box.
The OSW-U-0721-MV must always control Load 1, while its control of Load 2 is selected manually by opening and
closing the toggle switch.
