5. Make sure that the grounding resistance should be less than 5 Ohm.
6. In case grounding resistance is over 5 Ohm the additional ground rods may be needed, where as the
distance between both rods is at lest ground rod length.
4. How to install the ground rod.
A separately provided ground rod should be piled down into the high moisture ground.
The ground rod should be at least 30 centimeters placed underneath the ground level.
The ground rod is not less than 16 millimeters diameter and 240 centimeters in length.

Strip out the wire insulator, connect it to the ELB BREAKER terminal, Live wire (high potential) must
be connected to the “L” and Neutral line to the “N”, secure firmly with a screwdriver.
(Torque of about 12 kgf.cm.
should be applied).
3. The line of “L” and “N” must be carefully and correctly connected to the corresponding pole;
otherwise, it may affect the circuit and consequently causes damage to the unit or electrical harm.
