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
connections may carry voltage even if the motor shaft is not rotating.
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 shaft 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
connections) 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 60 V.
Secure hanging loads!
Built-in holding brakes do not ensure functional safety!
The user should consider required local safety standards in the case of hanging loads
(vertical axes) and the need to insure personnel safety by using additional safety
measures for hazard avoidance.
