1) The AUMA power class (A1, B1, ...) is indicated on the actuator controls name plate
Consider the motor starting current (IA) (refer to electrical data sheet) when selecting
the circuit breaker. We recommend tripping characteristics D or K for circuit breakers
in accordance with IEC 60947-2. For controls equipped with thyristors, we recommend
safety fuses instead of circuit breakers. However, the use of circuit breakers is
basically permitted.
For actuator controls equipped with a heating system and external electronics power
supply, the fuses for the heating system have to be provided by the customer (refer
to wiring diagram F4 ext.)

Refer to Technical data for options of isolated potentials.
Safety measures and safety equipment must comply with the respectively valid
national on site specifications. All externally connected devices shall comply with
the relevant safety standards applicable for the place of installation.
We recommend using connecting cables and connecting terminals according
to rated current (I
N
For device insulation, appropriate (voltage-proof) cables must be used. Specify
cables for the highest occurring rated voltage.
Use connecting cables, cable glands, reducers, blanking plugs with a minimum
temperature range of +80 °C.
To avoid contact corrosion, we recommend the use of sealing agents for cable
glands and blanking plugs made of metal.
For connecting cables exposed to UV radiation (outdoor installation), use UV
resistant cables.
For the connection of position transmitters, screened cables must be used.
Signal and fieldbus cables are susceptible to interference. Motor cables are
interference sources.
Lay cables being susceptible to interference or sources of interference at the
highest possible distance from each other.
The interference immunity of signal and fieldbus cables increases if the cables
are laid close to the earth potential.
If possible, avoid laying long cables and make sure that they are installed in
areas being subject to low interference.
Avoid parallel paths with little cable distance of cables being either susceptible
to interference or interference sources.
