Precautions during wiring
CAUTION
WARNING
Properly dispose of the packing materials. Plastic bags
pose suffocation hazard to children.
To prevent injury, install the controller on a flat surface
strong enough to support its weight.
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 this manual.
Improper installation may result in electric shock or fire.
To reduce the risk of damage to the controller,
malfunctions, smoke, or fire, do not connect the power
cable to the signal terminal block.
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.
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.
Use properly rated breakers and fuses (breaker, local
switch <switch + fuse>, no-fuse breaker). The use of a
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.
