Electrical - Ryobi GDM800 Operator's Manual

ELECTRICAL CONNECTION
This product has a precision-built electric motor. Do not
install this accessory to a garage door opener if the opener
is not connected to a power supply that is 120 volts, AC
only (normal household current), 60 Hz. A substantial
voltage drop will cause a loss of power and the motor will
overheat. If your product does not operate when installed
to the garage door opener, double-check the power supply,
breaker or GFCI.
GROUNDING INSTRUCTIONS
See Figure 1, page 11.
This product must be grounded. In the event of a malfunction
or breakdown, grounding provides a path of least resistance
for electric current to reduce the risk of electric shock. This
product is equipped with an equipment-grounding conductor
and a grounding plug. The plug must be plugged into a
matching outlet on the garage door opener. Do not modify
the plug provided or use adaptors.
WARNING:
Improper connection of the grounding plug can result in
a risk of electric shock. When repair or replacement of
the plug is required, do not connect the grounding wire to
either flat blade terminal. The wire with insulation having
an outer surface that is green with or without yellow
stripes is the grounding wire.
Check with a qualified electrician or service personnel if the
grounding instructions are not completely understood, or if
in doubt as to whether the product is properly grounded.
Repair or replace a damaged or worn plug immediately.

ELECTRICAL

This accessory should only be installed onto a garage door
opener that has a nominal 120 V circuit. The accessory's
grounding plug is similar to the plug illustrated in figure 1.
Always plug the accessory into an outlet on the garage door
opener with the same configuration as the plug. Do not use
an adapter with this product.
GROUND FAULT CIRCUIT INTERRUPTER
See Figures 2 and 3, page 11.
The 10 amp, 120 volt receptacles on the garage door opener
are protected by a Ground Fault Circuit Interrupter (GFCI),
which guards against the hazards of ground fault currents.
An example of ground fault current is the current that would
flow through a person who is using an appliance with faulty
insulation and, at the same time, is in contact with an electrical
ground such as a plumbing fixture, wet floor, or earth.
GFCI receptacles do not protect against short circuits,
overloads, or shocks.
The GFCI receptacles can be tested with the TEST and
RESET buttons.
To test:
 Open the console door.
 Depress the TEST button. This should cause the RESET
button to pop out.
 To restore power, depress the RESET button.
Perform this test monthly to ensure proper operation of the
GFCI.
