Low voltage and secondary overvoltage watch tests
Tests in the following pages (three tests) have to be done after replacing any primary or secondary
units or cards. It absolutely important because possible short circuit (e.g. improperly installed mica
insulator) may damage the machine heavily.
To execute following low voltage tests, Kemppi Multipower (and wire set) and digital multimeter is
required.
Be very careful and follow the instructions set by step to make everything in right order. Otherwise you
may damage the machine or the testing equipment.
Remember to measure DC-link is not charged while making any connections. In the case it is in high
voltage state you may injure yourself or damage the Kemppi multipower.
