5. Measure that the installation is de-energized. Use a quality voltage tester. If the
measurement requires removal or disassembly of shrouding or other cabinet structures,
obey the local laws and regulations applicable to live working (including – but not limited
to – electric shock and arc protection).
• Before and after measuring the installation, verify the operation of the voltage tester
on a known voltage source.
• Make sure that the voltage between the drive input power terminals (L1, L2, L3) and
the grounding (PE) busbar is zero.
• Make sure that the voltage between the drive output terminals (T1/U, T2/V, T3/W)
and the grounding (PE) busbar is zero.
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 even 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.
WARNING!
The busbars inside the cabinet of liquid-cooled drives are partially coated.
Measurements made through the coating are potentially unreliable, so only
measure at uncoated portions. Note that the coating does not constitute a safe
or touch-proof insulation.
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).
