CAUTION
WARNING
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.
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 electric shock, malfunctions, or fire,
seal the gap between the cable access holes with putty.
To reduce the risk of shorting, current leakage, electric
shock, or malfunctions, keep the cables out of contact with
controller edges.
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.
To reduce the risk of shorting, electric shock, fire, or
malfunction, do not touch the circuit board with tools or
with your hands, and do not allow dust to accumulate on
the circuit board.
