WARNING
!
Risk of improper electrical connection termination. Can cause building and equipment damage,
excessive heat at the terminations, smoke, fire, electric shock, serious injury and death.
Do not terminate different gauge wires to the power terminal block. Slack in the wiring may
generate heat and fire.Do not ground the shield of the communications cable to the indoor unit
frame or other grounded entities of the building.
NOTE
• When terminating wires of the same thickness, follow the instructions in
Figure 6-3.
• Attach the wire securely without placing external force on the terminal
block.
• Use an appropriately-sized screwdriver to tighten the terminals.
• Do not over-tighten the connections. Over-tightening may damage the
terminals.
• Never apply line-voltage power to the communications-cable terminal
block. If contact is made, the PCBs may be damaged.
• Always include some allowance in the wiring length when terminating.
Provide some slack to facilitate removal of electrical panels when servicing.
