1.2.1.6 Secure the Key
Remove any fitted key (if present) from the shaft before letting the motor run without coupled load,
to avoid the dangerous results of the key being thrown out by centrifugal forces.
CAUTION 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.
l
Measure the temperature, and wait until the motor has cooled down below 40°C
before touching it.
DANGER Grounding! 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.
l
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.
l
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.
l
The capacitors in the servo amplifier can still carry a dangerous voltage several
minute safter switching off the supply voltages. To be extra safe, measure the DC-
link voltage and wait until the voltage has fallen below 60 V.
WARNING Secure hanging loads!
Built-in holding brakes do not ensure functional safety!
l
Hanging loads (vertical axes) require an additional, external mechanical brake to
ensure personnel safety.
