Important! Repeat the measurement also with the DC voltage setting of the
tester. Measure between each phase and ground. There is a risk of dangerous
DC voltage charging due to leakage capacitances of the motor circuit. This
voltage can remain charged for a long time after the drive power-off. The
measurement discharges the voltage.
•
Make sure that the voltage between the drive DC terminals (UDC+ and UDC-)
and the grounding (PE) terminal is zero. In cabinet-built drives, measure
between the drive DC busbars (+ and -) and the grounding (PE) busbar.
6.
Install temporary grounding as required by the local regulations.
7.
Ask for a permit to work from the person in control of the electrical installation
work.
General notes
■
Printed circuit boards
WARNING!
Use a grounding wristband when you handle printed circuit boards. Do not
touch the boards unnecessarily. The boards contain components sensitive to
electrostatic discharge.
■
Optical components
WARNING!
Obey these instructions. If you ignore them, damage to the equipment can
occur.
•
Handle the fiber optic cables with care.
•
When you unplug the fiber optic cables, always hold the connector, not the cable
itself.
•
Do not touch the ends of the fibers with bare hands as the ends are extremely
sensitive to dirt.
•
Do not bend the fiber optic cables too tightly. The minimum allowed bend radius
is 35 mm (1.4 in).
Checking the insulation of the assembly
■
Measuring the insulation resistance 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.
