SECTION 10:
POWER OPTIONS AND WIRING
There are four possible configurations available to power the 1050 control board:
•
12 VDC battery charged by solar panel
•
12 VDC battery charged by AC-DC charger applied to battery
•
12 VDC battery charged by 10-35 VDC from Main DC Power input
•
10-35 VDC from AC-to-DC power supply to Main DC Power input (no battery)
• Disconnect power to the gate operator by manually
opening its dedicated circuit breaker before making
any mechanical or electrical adjustments.
• Use a 20 amp dedicated circuit breaker for each
installed gate operator.
• Open dedicated circuit breaker supplying power to
gate operator before a new installation or making any
modifications to an existing installation of this gate
operator.
•
All wiring connections must be made by a qualified
individual.
• Run individual circuits in separate U.L. Listed conduits.
Do not combine high voltage (120vac) power wiring
and low voltage (+12vdc to +24vdc) control wiring in
the same conduits.
CAUTION!
DO NOT WIRE AC POWER TO
THE CONTROL BOARD! THE
CONTROL BOARD OPERATES
ON DC VOLTAGES ONLY!
DANGER!
TO REDUCE THE RISK OF SEVERE
INJURY AND DEATH FOLLOW ALL
SAFETY PROCEDURES!
The 1050 control board operates ONLY on DC power from the battery or from the Main DC Power input.
Follow all safety warnings if installing AC power for conversion to DC for charging purposes or for powering
the board. Nice offers optional charging solutions.
SECTION 11:
120VAC ELECTRICAL WIRING SAFETY
IF AC POWER IS BEING RUN INTO THE CONTROL
BOX FOR CONVERSION TO DC,
THE GATE
OPERATOR SYSTEM SHOULD BE GROUNDED
THROUGH THE EARTH GROUND IN THE AC
MAINS WIRING SYSTEM (GREEN WIRE).
This
ground connection will prevent dangerous currents
from appearing on the metal control box, the actuator,
or the gate itself.
DANGER!
DO NOT WIRE AC MAINS
POWER TO METAL CONTROL
BOX WITHOUT EARTH GROUND
CONNECTION!
Nice recommends an 8 foot copper rod driven all the
way into the ground with a copper clamp and 12ga
copper wire minimum.
Connect ground wire to the grounding lug on the
lower left corner of the 1050 control board (FIGURE
11-1). Alternatively, bonding of the control box can be
done by drilling a hole in the control box, removing
the powder coating around the hole, and bonding the
copper ground wire to that area with a bolt.
