AUMA SAR 07.2 User Manual

External supply of the
electronics
For external electronics supply, the power supply of actuator controls must have an
enhanced isolation against mains voltage in compliance with IEC 61010-1 and the
output power has to be limited to 150 VA in compliance with IEC 61010-1.
Protection and sizing on
site
For short-circuit protection and for disconnecting the actuator from the mains, fuses
and disconnect switches have to be provided by the customer.
The current values for sizing the protection can be derived from the current
consumption of the motor (refer to motor name plate) plus the current consumption
of actuator controls.
We recommend adapting the switchgear sizing to the max. current (I
max
) and selecting
and setting the overcurrent protection device in compliance with the indications in
the electrical data sheet.

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.
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.
