Hot surface!
The surfaces of the motors can be very hot in operation, according to their protection
category. Risk of minor burns! The surface temperature can exceed 100°C. Measure the
temperature, and wait until the motor has cooled down below 40°C before touching it.
Earthing! High voltages!
It is vital that you ensure that the motor housing is safely earthed to the PE (protective
earth) busbar in the switch cabinet. Risk of electric shock. Without low-resistance
earthing no personal protection can be guaranteed and there is a risk of death from
electric shock.
Not having optical displays does not guarantee an absence of voltage. Power connec-
tions may carry voltage even if the motor is not turning.
Do not unplug any connectors during operation. There is a risk of death or severe injury
from touching exposed contacts. Power connections may be live even when the motor is
not rotating. This can cause flashovers with resulting injuries to persons and damage to
the contacts.
After disconnecting the drive from the supply voltage, wait several minutes before tou-
ching any components which are normally live (e.g. contacts, screw connections) or ope-
ning any connections.
The capacitors in the drive can still carry a dangerous voltage several minutes after swit-
ching off the supply voltages. To be quite safe, measure the DC-link voltage and wait until
the voltage has fallen below 40V.
Secure hanging loads!
Built-in holding brakes do not ensure functional safety! Hanging loads (vertical axes) re-
quire an additional, external mechanical brake to ensure personnel safety.
Evaluate chemical compatibility of the motor cable!
Compatibility of the cable to cleaning solutions used in the application should be evalua-
ted before subjecting the cable to long-term exposure to chemicals. Long-term exposure
of the motor cable to chemicals not compatible with the motor cable could result in conta-
mination of product, motor failure, and electrocution hazard due to the exposure of high
voltage wiring inside the motor cable.
Evaluate chemical compatibility of the optional cable tube!
Silicone tubing protects the cable and electrical interfaces on these motors from exposure
to cleaning solutions and avoids emissions from the motor cable. Exposure of the silicone
tubing to strong mineral acids should be avoided to avoid chemical degradation of the sili-
cone tubing. Compatibility of the silicone tubing with cleaning solutions used in the appli-
cation should be evaluated before subjecting the silicone tubing to long-term exposure to
chemicals. Long-term exposure of the silicone tubing to chemicals not compatible with
the silicone tubing could result in contamination of product, motor failure, and electrocu-
tion hazard due to the exposure of high voltage wiring inside the motor cable.
