Punch a hole at the rubber ring on the unit base. Then insert the electric
cable from the back.
❑
Strip the cable and connect to the earth leakage circuit breaker (ELCB).
Connect the line to the terminal L and the NEUTRAL to the N and
secure it tightly with screws.
❑
Connect the stripped ground wire to the ground terminal of the heater
base following the picture.

❑
Choose a humid area to put the copper electrode.
The minimum length of the copper electrode is 90 cm.
❑
The ground rod must be put under the ground at the minimum
of 70 cm away from the ground surface.
❑
Make sure that the resistance of the ground must not exceed
100 ohms.
❑
If the resistance exceed 100 ohms, it may be necessary to put
two or three electrodes for grounding.
