For motor with different current type/mains voltage/mains frequency (refer to motor name plate),
select fuse in accordance with electrical data sheet.
1)
The actuators are suitable for use in current circuits with a maximum short-circuit 1-phase AC current
value of 5,000 A root-mean-square (R.M.S). The output data of the fuses to be provided on site
2)
must not exceed the following values: 32 A/600 V at a maximum mains mains short circuit current
of 5,000 A AC.
Consider the max. current (I
max
) (refer to motor name plate or electrical data sheet)
when selecting the circuit breaker.
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. DC
current may be present within the PE conductor.
Implementation of overcurrent protection devices is not required. Actuator controls
are equipped with own protection mechanisms, adapted to the actuator system.
Therefore, we recommend refraining from using overcurrent protection devices.
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.

Refer to Technical data for options of isolated potentials.
