Precautions during wiring
To reduce the risk of electric shock or malfunctions, do
not touch the touch panel, switches, or buttons with a
pointy or sharp object.
To reduce the risk of damage to the controller, do not
directly spray insecticide or other flammable sprays on
the controller.
To reduce the risk of injury and electric shock, avoid
contact with sharp edges of certain parts.
To reduce the risk of injury, wear protective gear when
working on the controller.
Consult your dealer for the proper disposal of the
controller.
Do not install the unit where there is a risk of leaking
flammable gas.
If flammable gas accumulates around the unit, it may
ignite and cause a fire or explosion.
To reduce the risk of shorting, current leakage, electric
shock, malfunctions, smoke, or fire, do not install the
controller in a place exposed to water or in a
condensing environment.
Controller must be installed by qualified personnel
according to the instructions detailed in the Installation
Manual.
Improper installation may result in electric shock or fire.
Install the top case into the bottom case until it clicks.
To reduce the risk of damage to the controller,
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 the
Installation Manual.
To reduce the risk of electric shock, install a breaker
and a residual current circuit breaker on the power
supply.
To reduce the risk of electric shock, smoke, or fire,
install a breaker for each controller.
Use properly rated breakers and fuses (breaker, local
switch < fuse>, no-fuse breaker).
Breaker with a breaking capacity greater than the
specified capacity may cause electric shock,
malfunctions, 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 grounding 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.
To reduce the risk of electric shock, shorting, or
malfunctions, keep wire pieces and sheath shavings
out of the terminal block.
To reduce the risk of shorting, current leakage, electric
shock, or malfunctions, keep the cables out of contact
with controller edges.
To reduce the risk of electric shock, malfunctions, or
fire, seal the gap between the cables and cable access
holes with putty.
