Precautions For Relocating Or Repairing The Unit; Additional Precautions - Mitsubishi Electric AE-200A Installation Manual

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.
Electrical work must be performed by qualified personnel in accordance with local
regulations and the instructions provided in this manual. Only use specified cables and
dedicated circuits. Inadequate power source capacity or improper electrical work will
result in electric shock, malfunction, or fire.
To reduce the risk of electric shock, install an overcurrent breaker and an earth leakage
breaker on the power supply. To reduce the risk of electric shock, smoke, or fire, install an
overcurrent breaker for each controller.
Only use properly rated breakers (earth leakage breaker, local switch <switch + fuse that
meets local electrical codes>, moulded case circuit breaker, or overcurrent breaker). The
use of improperly rated breakers or the substitution of fuses with steel or copper wire may
result in electric shock, malfunction, 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 qualified personnel. 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 short circuits, electric shock, or malfunction, keep wire pieces and
sheath shavings out of the terminal block.
To reduce the risk of short circuits, current leakage, electric shock, or malfunction, keep
the cables out of contact with controller edges.
To reduce the risk of electric shock, malfunction, or fire, seal the gap between the cable
and the end of the conduit tube with putty.

1-4. Precautions for relocating or repairing the unit

The controller must be repaired or moved only by qualified personnel. Do not disassemble
or modify the controller. Improper installation or repair may result in injury, electric shock,
or fire.
To reduce the risk of short circuits, electric shock, malfunction, or fire, do not touch the
circuit board with tools or with your hands, and do not allow dust to accumulate on the
circuit board.

1-5. Additional precautions

To avoid damage to the controller, use appropriate tools to install, inspect, or repair the
controller.
