INSTALLATION STEP 9

Electrical Requirements

To reduce the risk of electric shock, your garage
door opener has a grounding type plug with a third
grounding pin. This plug will only fit into a grounding
type outlet.
If the plug doesn't fit into the outlet you have,
contact a qualified electrician to install the proper
outlet.
To avoid installation difficulties,
do not run the opener at this time.
If permanent wiring is required by your local code, refer to the following procedure:
To make a permanent connection through the
22mm diameter hole in top of opener (according to
local code):
• Remove opener cover screws and set the cover
aside.
• Remove attached 3-prong cord.
• Connect black (line) wire to black wire on terminal
block; white (neutral) wire to white terminal wire;
ground wire to green ground screw. The opener
must be grounded.
• Reinstall the cover.
To avoid installation difficulties,
do not run the opener at this time.
