44 Service Manual
The ISOMETER monitors the insulation charging stations for electric vehicles for DC be-
tween 0 and 1100Vdc.
This device protects both DC connectors in the output side. It is measuring constantly
the resistance between positive wire to the ground and negative wire to the ground.
If the resistance value is very low it will generate an alarm as it is needed a high value
to keep the safety.
