Prior to assembly and commissioning
to avoid injury of persons and damages
of the devices, it is absolutely necessary
to carefully read and observe these
instructions.

Necessary assembly, start-up, and
maintenance work must be performed
only by qualified, trained and authorized
personnel.

Mounting

The actuator should be mounted with the
valve stem in either horizontal position or
pointing upwards.

The actuator is fixed to the valve body by
means of a ribbed nut which requires no
tools for mounting. The ribbed nut should
be tightened by hand.

Wiring

Do not touch anything on the PCB!

Switch off the power line before wire the

actuator! Lethal voltage!

Wire the actuator according to the wiring
diagram.
