①. Fuse is located on the main board.
②. Install a circuit breaker at every power terminal near the units (indoor unit and
thermostat) with at least 3mm contact gap. The units must be able to be
plugged or unplugged.
③. Circuit breaker and power cord specifications listed in the above table are
determined based on the maximum power input of the units.
④. Specifications of power cords listed in the above table are applicable in a
working condition where ambient temperature is 40°C and multi-core copper
cable (e.g. YJV copper cable, with insulated PE and PVC sheath) is protected
by a conduit, and is resistant to 90°C in maximum (see IEC 60364-5-52). If
working condition changes, please adjust the specifications according to
national standards.
⑤. Specifications of circuit breaker are based on a working condition where the
working temperature is 40°C. If working condition changes, please adjust the
specifications according to national standards.
⑥. Adopt 5pc of AWG18 power cords to be the communication cords between
indoor unit and thermostat. The maximum length is 30m. Please select a
proper length according to local conditions. Communication cords must not be
twisted together.
⑦. The wire gauge of communication cord should not be less than AWG18. It’s
recommended to use AWG18 power cords as the communication cords.
