Elect rocut ion Hazard! HI GH VOLTAGE - Connect ions
in t erm inal block M1 are high volt age ( 120V / 60Hz) .
Before m aking connect ions, verify appliance is
disconnect ed from power supply. Respect t he input
polarity on t erm inal block M1: L ( LI NE) - N ( NEUTRAL) .
Failure t o follow t hese inst ruct ions WI LL result in deat h
or serious inj ury.

Elect rical shock hazard. Turn OFF elect rical power
supply at service panel before m aking elect rical
connect ions. Failure t o do so could result in deat h or
serious inj ury.
