14.3. Precautions on wiring of power supply and inter-

unit wiring

Use a round crimp-style terminal for connection to the power 
supply terminal board. In case it cannot be used due to 
unavoidable reasons, be sure to observe the following 
instruction.

- Do not connect wires of different gauge to the same power 

supply terminal. (Looseness in the connection may cause 
overheating.)

- When connecting wires of the same gauge, connect them 

according to the below figure.

Use the correct screwdriver to tighten the terminal screws.
Small screwdrivers can damage the screw head and prevent 
appropriate tightening.

Over-tightening the terminal screws can damage the screws.

See the table below for tightening torques for the terminal 
screws.

Refer to the installation manual attached to the indoor unit for 
wiring of indoor units, etc.

Attach an earth leakage breaker and fuse to the power supply 
line.

In wiring, make certain that prescribed wires are used, carry out 
complete connections, and fix the wires so that outside forces 
are not applied to the terminals.

14.4. Specifications of standard wiring components

Only for RZQ(S)G*V1 + R125Y1: 

Equipment complying with EN/IEC 61000-3-12

(1)

.

Only for RZQG100~140Y1 + RZQSG140Y1: 

Point for attention regarding quality of the public electric 
power supply

This equipment complies with EN/IEC 61000-3-12

(1)

 provided 

that the short-circuit power S

sc

 is greater than or equal to 

1170 kVA at the interface point between the user's supply and 
the public system. 
It is the responsibility of the installer or user of the equipment to 
ensure, by consultation with the distribution network operator if 
necessary, that the equipment is connected only to a supply with 
a short-circuit power S

sc

 greater than or equal to 1170 kVA.

Above indicated value is the most stringent value. Refer to 
databooks for specific product-data.
