Additional instructions and notes
WARNING!
Obey these instructions. 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 or
maintenance work.
•
Make sure that the electrical power network, motor/generator, and
environmental conditions agree with the drive data.
•
Do not do insulation or voltage withstand tests on the drive.
•
If you have a cardiac pacemaker or other electronic medical device, keep away
from the area near motor, drive, and the drive power cabling when the drive
is in operation. There are electromagnetic fields present which can interfere
with the function of such devices. This can cause a health hazard.
Note:
•
When the drive is connected to the input power, the motor cable terminals
and the DC bus are at a dangerous voltage.
The brake circuit, including the brake chopper and brake resistor (if installed)
are also at a dangerous voltage.
After disconnecting the drive from the input power, these remain at a
dangerous voltage until the intermediate circuit capacitors have discharged.
•
External wiring can supply dangerous voltages to the relay outputs of the
control units of the drive.
•
The Safe torque off function does not remove the voltage from the main and
auxiliary circuits. The function is not effective against deliberate sabotage or
misuse.
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.
