Wiring Requirements
Preferred Connection
This product is for use on a nominal 120 VAC circuit and has a
grounding plug that looks like the plug illustrated. Using a
higher voltage circuit is dangerous and may result in a fire or
other accident.
Temporary Connection

house wiring, attaching the adaptor grounding screw tab to the
cover screw will NOT ground the unit. If there is any doubt
whether the cover screw is grounded, have it checked by a qualified
electrician or service professional.
A temporary connection with a two-prong adaptor may be made
where local codes permit, provided that the adaptor is grounded.
