Precautions during installation

WARNING
Do not install the controller where there is a risk of
leaking flammable gas. If flammable gas accumulates
around the controller, it may ignite and cause a fire or
explosion.
Properly dispose of the packing materials. Plastic bags
pose suffocation hazard to children.
CAUTION
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.
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.
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.
To avoid injury from broken glass, do not apply
excessive force on the glass parts.
To reduce the risk of injury, wear protective gear when
working on the controller.
Do not directly stare at the LED light, as this may
damage your eyes.
Take appropriate safety measures against earthquakes
to prevent the controller from causing injury.
To prevent injury, install the controller on a flat surface
strong enough to support its weight.
When attaching the cover and the top casing to the
bottom casing, push it until it they click into place. If
they are not properly locked into place, they may fall,
causing personal injury, controller damage, or
malfunctions.
All electric work must be performed by a qualified
electrician according to the local regulations,
standards, and the instructions detailed in the
Installation 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.
To reduce the risk of electric shock, malfunctions, or
fire, seal the gap between the cables and cable access
holes with putty.
