1. Check local building codes.
• Does building code require permanent wiring?
– If not, skip to step 9.
–
If yes, have an electrician perform steps 2
through 8.
To reduce the risk of electrical shock, this
equipment has a grounding type plug that has a
third (grounding) pin. This plug will only fit into a
grounding type outlet. If the plug does not fit into
the outlet, contact a qualified electrician to install
the proper outlet. DO NOT change the plug in
any way. The door operator must be properly
grounded to prevent personal injury and damage
to the components.
The electrical power to the door operator MUST
BE removed when motor cover is removed.
Electrical power must remain off while making
electrical connections.
