Secure the wiring in the order shown below.
■
Lay the electrical wiring so that the front cover does not rise up
when doing wiring work and attach the front cover securely (see
figure 2 ).
■
Follow the electric wiring diagram for electrical wiring works (the
electric wiring diagrams are located on the rear side of doors 1
and 2).
■
Form the wires and fix the cover firmly so that the cover may be
fit in properly.
Precautions on wiring of power supply
■
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.
■
Attach an earth leakage circuit 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.
Specifications of standard wiring components
Door 1: compressor compartment and electrical parts: X1M
For V3 model: Equipment complying with EN/IEC 61000-3-12
(European/International Technical Standard setting the limits for
harmonic currents produced by equipment connected to public
low-voltage systems with input current >16 A and

The wiring diagram can be found on the inside of the front plate of the
unit.
Connection of the backup heater power supply
Power circuit and cable requirements
This power circuit must be protected with the required safety devices
according to local and national regulations.
Select the power cable in accordance with relevant local and national
regulations. For the maximum running current of the backup heater,
refer to the table below.

NOTE
The earth leakage circuit breaker must be a
high-speed type breaker of 30 mA (<0.1 s).
■
Be sure to use a dedicated power circuit for the
backup heater. Never use a power circuit shared by
another appliance.
■
Use one and same dedicated power supply for the
unit, backup heater and booster heater (domestic hot
water tank).
