Brake resistor assembly for R1...R3
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, commissioning or maintenance work.
1. Stop the drive and do the steps in section
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.

Grounding system compatibility check

The standard drive can be an be installed to a symmetrically grounded TN-S system.
For other systems, see sections
below.

EMC filter

A drive with EMC filter connected can be installed to a symmetrically grounded TN-S
system. If you install the drive to another system, you may need to disconnect the EMC
