Safety
WARNING!
If you are not a qualified electrical professional, do not do installation or
maintenance work. Obey the safety instructions of the drive. If you ignore them,
injury or death, or damage to the equipment can occur.
Measuring the insulation
￭ Measuring the insulation of the drive
WARNING!
Do not do any voltage withstand or insulation resistance tests on any part of the
drive as testing can damage the drive. Every drive has been tested for insulation
between the main circuit and the chassis at the factory. Also, there are
voltage-limiting circuits inside the drive which cut down the testing voltage
automatically.
￭ Measuring the insulation of the input power cable
Before you connect the input power cable to the drive, measure its insulation according to
local regulations.
