0EHN Series).
Make sure that the initial settings are OK. If not, readjust the
G3PX.
Make sure that terminals 18 and 19 are open if the supply fre-
quency is 50 Hz. These terminals must be short-circuited if the
supply frequency is 60 Hz.
Make sure that the load current is large enough.

Countermeasure 2: When the supply current is less than 50%, in-
crease the number of turns. When the supply current is 50% of
the rated current, the wires must be coiled twice on the CT Unit.
When the supply current is 25% of the rated current, the wires
must be coiled three to four times on the CT Unit.

Be sure to press the RESET button with power supplied to the
G3PX.
The following wiring will be required if the breaker or contactor
connected between the power supply and the G3PX is operated
