Precautions during wiring
CAUTION
WARNING
To reduce the risk of shorting, current leakage, electric
shock, malfunctions, smoke, or fire, do not install AHC in a
place exposed to water or in a condensing environment.
AHC must be installed by qualified personnel according to
the instructions detailed in this manual.
Improper installation may result in electric shock or fire.
To reduce the risk of damage to AHC, malfunctions,
smoke, or fire, do not connect the power cable to the signal
terminal block.
Properly secure the cables in place and provide adequate
slack in the cables so as not to stress the terminals.
Improperly connected cables may break, overheat, and
cause smoke or fire.
To reduce the risk of injury or electric shock, switch off the
main power before performing electrical work.
All electric work must be performed by a qualified
electrician according to the local regulations, standards,
and the instructions detailed in this manual.
Capacity shortage to the power supply circuit or improper
installation may result in malfunction, electric shock,
smoke, or fire.
To reduce the risk of current leakage, overheating, smoke,
or fire, use properly rated cables with adequate current
carrying capacity.
Proper grounding must be provided by a licensed
electrician.
Do not connect the protective ground wire to a gas pipe,
water pipe, lightning rod, or telephone wire. Improper
grounding may result in electric shock, smoke, fire, or
malfunction due to electrical noise interference.
