Measuring the insulation resistance 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, 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 installed to a symmetrically grounded TN-S system. For
other systems, see sections
and
Ground-to-phase varistor (page 94)
below.

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