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.
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).
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.
■
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.
If you are not a qualified electrical professional, do not do grounding work.
•
Always ground the drive, the motor and adjoining equipment. This is necessary for the
personnel safety.
•
Make sure that the conductivity of the protective earth (PE) conductors is sufficient and
that other requirements are met. See the electrical planning instructions of the drive.
Obey the applicable national and local regulations.
•
When using shielded cables, make a 360° grounding of the cable shields at the cable
entries to reduce electromagnetic emission and interference.
•
In a multiple-drive installation, connect each drive separately to the protective earth
(PE) busbar of the power supply.
