Brake resistor and resistor cable
Check the insulation of the brake resistor assembly (if present) as follows:
1. Check that the resistor cable is connected to the resistor, and disconnected from
the drive output terminals R+ and R-.
2. 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.
Checking the combatibility with IT (ungrounded) and TN (corner
grounded) systems
A drive equipped with no EMC filter or with optional EMC filter +E210 is suitable for
IT (ungrounded) and TN (grounded) systems.
