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:
•
The motor cable terminals of the drive are at a dangerous voltage when the input
power is on, regardless of whether the motor is running or not.
•
When the input power is on, the drive DC bus is at a dangerous voltage.
If brake chopper and resistor are in use, they are at a dangerous voltage.
•
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 wrist band when you handle printed circuit boards. Do not touch
the boards unnecessarily. The boards contain components sensitive to electrostatic
discharge.
■
Grounding
These instructions are for all personnel who are responsible for the grounding of the
drive.
WARNING!
Obey these instructions. If you ignore them, injury or death, or equipment
malfunction can occur, and electromagnetic interference can increase.
