BEFORE PERFORMING ANY ELECTRICAL
OR WIRING WORK, TURN OFF THE MAIN
POWER TO THE SYSTEM.
• Prepare the cable for connection:
MINIMUM CROSS-SECTIONAL AREA OF
POWER AND SIGNAL CABLES
• Using wire strippers, strip the rubber jacket from
both ends of cable to reveal about 40mm/1.75" of
wire inside.
• Strip the insulation from the ends of the wires.
• Using a wire crimper, crimp u-lugs on the ends of
the wires.
PAY ATTENTION TO LIVE WIRE
While crimping wires, make sure you clearly
distinguish the Live (“L”) Wire from other wires.
ALL WIRING MUST PERFORMED STRICTLY
IN ACCORDANCE WITH THE WIRING
DIAGRAM LOCATED INSIDE THE OUT-
DOOR UNIT'S WIRE COVER.
• Unscrew the electrical wiring cover and remove it.
• Unscrew the cable clamp below the terminal block
and place it to the side.
• Match the wire colors/labels with the labels on the
terminal block, and firmly screw the u-lug of each
wire to its corresponding terminal.
• After checking to make sure every connection is
secure, loop the wires around to prevent rain water
from flowing into the terminal.
• Using the cable clamp, fasten the cable to the unit.
Screw the cable clamp down tightly.
• Insulate unused wires with PVC electrical tape.
Arrange them so that they
DO NOT
touch any
electrical or metal parts.
• Replace the wire cover on the side of the unit,
and screw it in place.
