ELECTRIC SHOCK CAUTION
WARNING
CAUTION
Caution when servicing the switch box
Caution when performing other servicing
1. Before obtaining access to terminal devices, all supply circuits must be interrupted because units at standstill
may be in a pre-heating mode and start automatically.
2. Be aware that temperature of switch boxes can be extremely high.
3. Do not touch the switch box for another 10 minutes after turning off the circuit breaker. Even after 10 minutes,
always measure the voltage at the terminals of main circuit capacitor or electrical parts and make sure that
those voltages are 50 V DC or less. (Always touch the earth terminal first before pulling out or plugging in
connectors in order to discharge static electricity. This to prevent the PCB from being damaged.)
4. After confirming the main circuit capacitor voltage drop, pull out the outdoor unit fan connector. Make sure not
to touch any live parts during this action. (Strong adverse winds which let the outdoor unit fan rotate, induce
a risk of electrical shock because the fan rotation makes the capacitor store electricity.)
Do never connect power supply cables to compressors (U,V,W) directly. The compressor may burn out.
Fanmotor connectors:
X1A,X2A / X3A,X4A / X5A,X6A
