Installing electrical connections
In actuators of the respective series, connectors with bayonet coupling are used. These are
connectors with an additional vibration O-ring.
- When using M23 screw counter plugs, the O-ring remains in place to protect against
loosening due to vibration on the mounting socket.
- When using
counter plugs with bayonet coupling
the O-ring must be
removed
.
- The maximum line length without disconnection points is 50 m. Observe also the maximum
permissible line lengths of the servo converter being used.
Electrically live components may result in electric shocks if touched
and can cause serious injuries and even death.
Observe the five safety rules of electrical engineering before starting
electrical installation work:
- Disconnect.
- Secure against being switched on again.
- Check that there is no voltage.
- Ground and short-circuit.
- Cover neighboring and electrified parts.
Check that protective caps are on the plugs. If protective caps are
missing, check the plugs for damage and soiling.
Electric operation in moist areas may result in electric shocks and can
cause serious injuries and even death.
Carry out the electrical assembly only in dry areas.
During generator operation, voltage is induced. This can lead to lethal
current pulses.
Ensure that no plugs and connections are exposed during generator
operation.
The cables of all servo actuators need to be laid out in such a way that
a minimum bending radius of 10 x diameter is kept. Torsional load of
the cables should be avoided.
