Earthing!
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 eart-
hing no personal protection can be guaranteed and there is a risk of death from electric
shock.
High voltages!
Keep the switching cabinet closed when the equipment is in operation. Not having optical
displays does not guarantee an absence of voltage. Power connections may carry vol-
tage 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 servo amplifier from the supply voltage, wait several minutes
before touching any components which are normally live (e.g. contacts, screw connec-
tions) or opening any connections.
The capacitors in the servo amplifier can still carry a dangerous voltage several minutes
after switching 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.
