13.7. ELECTRICAL WIRING CONNECTION
The electrical wiring connection for the unit is shown below:
1. Cut out the centre of the rubber bushing in the wiring connection
hole, as shown in next figure
Cut inside
2. Connect the cable of an optional remote control switch or an optional
extension cable to the connectors on the printed circuit board inside
the electrical box through the connecting hole in the cabinet.
3. Connect the power supply and earth wires to the terminals in the
electrical box.
4. Tightly clamp the wires using the cord clamp inside the electrical box.
5. Seal the wiring connection hole after running the cables with the seal
material to protect the unit from condense water or insects.
6. In the case that the power cables are connected in series,check the
amount of current is less than 50 A.
Select the main switches in according to the next table:

Field Minimum Wire Sizes for Power Source
Ensure that the field-supplied electrical components (mains power
switches, circuit breakers, wires, connectors and wire terminals) have
been properly selected according to the electrical data indicated.
Make sure that they comply with national and regional electrical
codes.

NOTE:
The above wire sizes marked with (*1) are selected at the
−
maximum current of the unit according to the European Standard,
EN60 335-1.
Use a shielded cable and connect it to ground.

In the case that power cables are connected in series, add each
−
unit maximum current and select wires below.
Follow local codes and regulations when selecting field wires,
−
Circuit breakers and Earth Leakage breakers
Use the wires which are not lighter than the ordinary
