Description
It is vital that you ensure the motor housing is safely earthed to the PE (protective earth)
busbar in the switch cabinet.
Risk of electric shock.
l
Without low-resistance earthing, no personal protection can be
l
guaranteed and there is a risk of death from electric shock.
Not having optical displays does not guarantee an absence of voltage.
l
Power connections may carry voltage even if the motor is not
l
turning.
Do not unplug any connectors during operation.
l
There is a risk of death or severe injury from touching exposed
l
contacts.
Power connections may be live even when the motor is not
l
rotating.
This can cause flashovers with resulting injuries to persons and
l
damage to the contacts.
After disconnecting the drive from the supply voltage, wait several
l
minutes before touching any components which are normally live (e.g.,
contacts, screw connections) or opening any connections.
The capacitors in the drive can still carry a dangerous voltage several
l
minutes after switching off the supply voltages.
To be safe, measure the DC-link voltage and wait until the
l
voltage has fallen below 50V
Built-in holding brakes do not ensure functional safety!
l
Hanging loads (vertical axes) require an additional, external mechanical
l
brake to ensure personnel safety.
Compatibility of the cable to cleaning solutions used in the application
l
should be evaluated before subjecting the cable to long-term exposure
to chemicals.
Long-term exposure of the motor cable to chemicals not compatible with
l
the motor cable could result in contamination of product, motor failure,
and electrocution hazard due to the exposure of high voltage wiring
inside the motor cable.
The motor housing is made of anodized aluminum.
Avoid direct coupling of this motor to more active metals such as
l
stainless steel or carbon steel in wet environments to prevent galvanic
corrosion.
Galvanic corrosion could result in contamination of product, failure of
l
motor mounting and motor failure.
Failure of the motor mounting could lead to electrocution hazard
l
due to failure of electrical terminations or the motor cable as a
result strain on the motor cable.
Always use supplied seals and mounting material (screws) when
l
installing the AKMA motor.
See (➜ Galvanic Corrosion # 20).
