Electrical connection
The actuators must always be powered via a prefuse of max. 6.3 AT
(as per DIN EN 6012- 2/5)
For the protective earth connection, the housing of all variants has a marked PE
connecting terminal. A tightening torque of 1.2 Nm must be observed for fitting the
screw
The supplied RAST3.5 connectors or RAST5 connectors must be used with screw
terminals for electrical connections. A tightening torque of 0.25 Nm must be
observed for fitting the screw
Note!
The connection of fuel valves is only permitted on fused output terminals, see chapter
Connection diagrams. For this purpose, specific unit variants are available fitted with
a unit-internal, non-replaceable fuse. The unit-internal fuse is used to protect each
switching contact from welding in the event of external short-circuit. In addition,
please note that the maximum current load for the fused output terminals is reduced,
see chapter Connection diagrams.

SELV or PELV depends on the safety class of the connected components. In the
case of PELV, the relevant component is connected to protective earth.
