Dangerous Voltage
1.1 Safety Precautions in Repair
Be sure to disconnect all remote electric power supplies before servicing. Internal
components and circuit boards are at main potential when the equipment is
connected to the power cables. This voltage is extremely dangerous and may
cause death or severe injury if come in contact with it.
Do not touch the discharging refrigerant gas during the repair work.
The refrigerant gas can cause frostbite.
Release the refrigerant gas completely at a well-ventilated place first.
Otherwise, when the pipe is disconnected, refrigerant gas or refrigerating
machine oil discharges and it can cause injury.
When the refrigerant gas leaks during work, execute ventilation. If the refrigerant
gas touches to a fire, poisonous gas generates. A case of leakage of the
refrigerant and the closed room full with gas is dangerous because a shortage of
oxygen occurs. Be sure to execute ventilation.
When removing the front panel or cabinet, execute short-circuit and discharge
between high voltage capacitor terminals. If discharge is not executed, an electric
shock is caused by high voltage resulted in a death or injury.
Be sure to provide the grounding when repairing the equipment in a humid or
wet place, to avoid electrical shocks.
