Precautions during wiring
WARNING
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.
CAUTION
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.
Precautions for moving or repairing the controller
WARNING
The controller should be repaired or moved only by
qualified personnel.
Do not disassemble or modify the controller.
Improper installation or repair may cause injury, electric
shock, or fire.
CAUTION
To reduce the risk of electric shock, shorting, or
malfunctions, keep wire pieces and sheath shavings
out of the terminal block.
Use properly rated breakers and fuses (breaker, local
switch <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.
Securely seal the cable access holes with putty to
prevent condensation, water, and insects from entering
and causing electric shock, malfunctions, or fire. Water
infiltration and condensation formed inside the unit may
damage the circuit board.
