Section 2 - Ac Power To Operator(S); High Voltage Wire Runs - DoorKing 9500 Series Installation & Owner's Manual

SECTION 2 - AC POWER TO OPERATOR(S)

Before attempting to connect any wiring to the operator, be sure that the circuit breaker in the electrical panel is in the OFF
position. Permanent wiring must be installed to the operator as required by local electrical codes. It is recommended that a
licensed electrical contractor perform this work.
Since building codes vary from city to city, we highly recommend that you check with your local building department prior
to installing any permanent wiring to be sure that all wiring to the operator (both high and low voltage) complies with local
code requirements.
Typical Grounding Sources
IMPORTANT: Ground wire shown without safety protection for clarity. Make sure ground wire is protected from being touched or electrical
shock could occur!

2.1 High Voltage Wire Runs

The 9500 draws significant power and should have a "Dedicated" circuit breaker at the power source.
If power wiring is greater than the maximum distance shown, it is recommended that a service feeder be installed. When large
gauge wire is used, a separate junction box must be installed for the operator connection. The wire table is based on stranded
copper wire. Wire run calculations are based on the NEC recommended maximum 3% voltage drop on the power line, plus an
additional 10% reduction in distance to allow for other losses in the system.
Never
run low voltage rated wire insulation in the same conduit as high voltage rated wire insulation.
This table illustrates the high voltage AC power wire size and distance limitations.
