6.1. Electrical requirement
Voltage rating
Operating range
• Select the power cable type and size in accordance with relevant local and national
regulations.
• Specifi cations for local wiring power cord and branch wiring are in compliance with local code.
• Select the correct cable type and size according to the country or region's regulations.
• Max. wire length: Set a length so that the voltage drop is less than 2%. Increase the
wire diameter when the wire length is long.
Refer to the table for the breaker specifi cations of each installation condition.
Perform the power crossover wiring within the range of the same refrigerant system. When
the crossover wiring is done, make a connection for indoor unit to satisfy conditions A and
B below.
A. Current breaker requirements
Model
ARUH36RLAV
ARUH48RLAV
ARUH60RLAV
MCA: Minimum Circuit Ampacity
MOP: Maximum Overcurrent Protection
When the power crossover wiring is done, make it so that the total of the MCA of the con-
nected indoor equipment does not exceed the 15 A.
B. Earth leakage breaker requirements
Breaker capacity
30 mA, 0.1 sec or less
100 mA, 0.1 sec or less
200 mA, 0.1 sec or less
If the number of units of connected indoor unit exceeds the upper limit, either add breakers
or use a breaker with large capacitance.
