Installation/assembly
•
Ensure that the product is installed and cooled according to the regulations in the
documentation.
•
Protect the product from strong mechanical strain.
•
The product and its mounting parts must never protrude into the path of persons or
vehicles.
•
Ensure that components are not deformed and insulation spaces are not changed,
particularly during transportation and handling.
•
Electric components must not be mechanically damaged or destroyed.
•
If you remove mechanical strained or heavy components, secure the construction
to prevent injuries.

Electric work
2.9.1
Carrying out electric work safely
Observe the following information to carry out electrical work safely during installation
and maintenance:
•
Electrical work may be carried out only by electrically skilled persons.
•
Always adhere to the 5 safety rules for working on electrical components:
– Disconnect
– Secure the drive against restart
– Check that no voltage is applied
– Ground and short-circuit it
– Cover or safeguard neighboring live parts
•
When the device is switched on, dangerous voltages are present on all power con-
nections as well as on any connected cables and terminals. This is also the case
even if the motor is at standstill.
•
Ensure that the connection boxes are closed and screwed down before applying
the supply voltage.
•
Ensure that all required covers are mounted before applying the supply voltage.
2.9.2
Regenerative operation of drives
Moving the output element (e.g. coasting) generates a voltage at the live components
of the motor connection. Observe the following information to avoid electric shock:
•
Do not touch open live components (e.g. male contacts of the plug connector, ter-
minals).
•
Secure all open live components with a touch guard.
•
Secure the output shaft against rotation when working without touch guard.
