3�5�7�- LEAKAGE CURRENT CONNECTION, IΔ
To measure the leakage current, an earth leakage transformer must be used, such as WGS.
The leakage current transformer must be connected such as to measure the current of the
capacitor bank. This will detect any leakage in the capacitors of the capacitor bank.

Note: The earth leakage transformer must have a ratio of 500 turns. The maximum leakage
current that the unit can measure correctly is 1.5A AC, even though the maximum input is 5A
AC via the earth leakage transformer.
Do not operate the leakage current transformer with the Controller MASTER
control VAR FAST powered on.
