Break resistor assembly insulation
• Check that the resistor cable is connected to the resistor, and disconnected from
the drive output terminals R+ and R-.
• At the drive end, connect the R+ and R- conductors of the resistor cable together.
Measure the insulation resistance between the combined conductors and the PE
conductor by using a measuring voltage of 1 kV DC. The insulation resistance
must be higher than 1 Mohm.
