Daikin BEV Series Installation Manual page 13

• All wiring must be performed by an authorized electrician.
• One BEV unit is connected to one indoor unit. Mark each indoor unit and BEV unit as unit A, unit B..., and be
sure the terminal block wiring to the outdoor unit are properly matched. If wiring and piping between the outdoor
unit and an indoor unit and BEV unit are mismatched, the system may cause a malfunction.
• A circuit breaker capable of shutting down power supply to the entire system must be installed.
• Refer to the installation manual attached to the outdoor unit for the size of power supply wiring connected
to the outdoor unit, the capacity of the circuit breaker and switch, and wiring instructions.
• Be sure to ground the air conditioner.
• Do not connect the ground wire to gas and water pipes, lightning rods, or telephone ground wires.
• Gas pipes : might cause explosions or fire if gas leaks.
• Water pipes : no grounding effect if hard vinyl piping is used.
• Telephone ground wires or lightning rods : might cause abnormally high electric potential in the ground
during lighting storms.
