Precautions

Thermistor cable and remote controller wire should be located at
least 50 mm away from power supply wires and from wires to
the controller. Not following this guideline may result in
malfunction due to electrical noise.

Use only specified wires, and tightly connect wires to the
terminals. Keep wiring in neat order so that it does not obstruct
other equipment. Incomplete connections could result in
overheating, and in worse case electric shock or fire.

Connecting the wiring: EKEXMCBV3

Connect the wires to the terminal board according to the wiring
diagram in 

figure 2

. See 

figure 3

 for wiring intake in the control

box. The wiring intake hole indication H1 refers to the H1 cable
of the corresponding wiring diagram. There are 2 wiring intake
holes to allow for branching of the communication wire.

Connect cables according to specifications of the next table.
