2.9.1 Stationary application
Necessary preventive measure for the product is:
Type of energy transfer Preventive measure
Direct power supply • Ground connection
2.9.2 Regenerative operation
The drive is operated as a generator due to the kinetic energy of the system/machine.
Before opening the connection box, secure the output shaft against rotation.
2.10 Startup/operation
Observe the safety notes in the chapters Startup and Operation in this documentation.
Make sure the connection boxes are closed and screwed before connecting the sup-
ply voltage.
Depending on the degree of protection, products may have live, uninsulated, and
sometimes moving or rotating parts, as well as hot surfaces during operation.
When the device is switched on, dangerous voltages are present at all power connec-
tions as well as at any connected cables and terminals. This also applies even when
the product is inhibited and the motor is at standstill.
Do not separate the connection to the product during operation. This may result in
dangerous electric arcs damaging the product.
If you disconnect the product from the voltage supply, do not touch any live compon-
ents or power connections because capacitors might still be charged. Observe the fol-
lowing minimum switch-off time:
5 minutes.
Observe the corresponding information signs on the product.
The fact that the operation LED and other display elements are no longer illuminated
does not indicate that the product has been disconnected from the supply system and
no longer carries any voltage.
Mechanical blocking or internal protective functions of the product can cause a motor
standstill. Eliminating the cause of the problem or performing a reset may result in the
drive restarting automatically. If, for safety reasons, this is not permitted for the drive-
controlled machine, first disconnect the product from the supply system and then start
troubleshooting.
Risk of burns: The surface temperature of the product can exceed 60 °C during opera-
tion. Do not touch the product during operation. Let the product cool down before
touching it.
2.11 Magnetic fields
The device contains permanent magnets that create strong magnetic fields even when
de-energized. Magnetic fields may pose a health risk. This especially applies to per-
sons with active medical implants. During operation, additional electromagnetic fields
are generated.
