8-3 POWER CIRCUIT, SAFETY DEVICE AND CABLE REQUIREMENTS
• A power circuit (Refer to Table 6) must be provided for connection of the unit. This circuit must be protected with the
required safety devices, i.e. a main switch, a slow blow fuse on each phase and an earth leakage circuit breaker.
• When using residual current operated circuit breakers, be sure to use a high-speed type (0.1 second or
less) 30mA rated residual operating current.
• Use copper conductors only.
• Use insulated wire for the power cord.
• Select the power supply cable type and size in accordance with relevant local and national regulations.
• Specications for local wiring are in compliance with IEC60245.
• Use wire type H05VV-U3G for power supply wiring. And the size must comply with local codes.
• Use vinyl cord with sheath or cable (2 wire) of 0.75-1.25mm
2
for transmission wiring.
• The transmission wire lengths are as follows:
Between the BS unit and indoor units: Max. 1,000 m
Between the BS unit and outdoor unit: Max. 1,000 m
Between BS units: Max. 1,000 m
Total wiring length: 2,000 m or less
