Measuring the insulation of the brake resistor circuit
WARNING!
Obey the safety instructions of the drive. If you ignore them, injury or death, or
damage to the equipment can occur.
If you are not a qualified electrical professional, do not do installation or
maintenance work.
1. Stop the drive and do the steps in section
Electrical safety precautions (page 17)
before you start the work.
2. Make sure that the resistor cable is connected to the resistor and disconnected from
the drive output terminals.
3. At the drive end, connect the R+ and R- conductors of the resistor cable together.
Measure the insulation resistance between the conductors and the PE conductor
with a measuring voltage of 1000 V DC. The insulation resistance must be more
than 1 Mohm.
