▪ Record the conditions of the breakers in the checklist (last pages).
▪ Check for contacts that are welded at breakers and contactors.
If contacts are found welded, replace breaker(s) and/or contactor(s).
▪ Remove the converter mains lines (frontal and rear converter) from contactor ENK1 :1 :3 :5.
Measure with an ohmmeter each line against the others (of each converter).
There should be no short-circuit, the meter should display 2MΩ ±5% after at least 20 seconds
(filter resistors).
