the circuit breaker. We recommend tripping characteristics D or K for circuit breakers
in accordance with IEC 60947-2. For controls with thyristors, we recommend safety
fuses instead of circuit breakers.
We recommend refraining from using residual current devices (RCD). However, if
an RCD is used within the mains, the residual current device must be of type B.
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.)

If actuator controls are mounted separately from actuator (actuator controls on wall
bracket): Consider length and cross section of connecting cable when defining the
protection required.
All input signals (control inputs) must be supplied with the same potential.
All output signals (status signals) must be supplied with the same potential.
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 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 cable with appropriate minimum rated temperature.
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.
