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
2a
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.
