Electric work
2.8.1
Carrying out electric work safely
Observe the following information to carry out electrical work safely during installation
and maintenance:
•
Electrical work may only be carried out 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 all required covers are mounted before applying the supply voltage.
2.8.2
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.
2.8.3
Disconnecting and connecting plug-in connections while voltage is applied
An electric arc may occur when plug-in connections are disconnected or connected
while voltage is applied (e.g. connection between drive and control). Observe the fol-
lowing to avoid risk of injury, risk of electric shock and damage to property:
•
Ensure that the product is de-energized before disconnecting and connecting the
plug-in connections.
