Connection to power supply/potential-free contact
Warning! Risk of injury from electrical voltage
All work on electrical components must be carried out by suitably
qualified technical personnel!
Models ED3007, ED3030 and ED3100 are equipped with a potential-free contact,
in addition to the power mains connection (not available for ED3002 and ED3004).
Models ED3007 to ED3100 therefore feature two connections with matching
adapters:
Adapter for supply voltage: magnetic valve connector "type B plug" industrial
standard (11 mm) 2 + PE (see figure, item 1)
Adapter for potential-free contact: magnetic valve connector "type C plug"
industrial standard (9,4 mm) 3 + PE (see figure, item 2)
Connection to supply voltage
Beware of electric shock in case of a fault!
The drain features a ground connection. Its purpose is to provide a safety
cut-out of the condensate drain in case of an error, provided a ground
fault circuit interrupter has been installed upstream of the condensate
drain.
Otherwise there is the risk of an electric shock in case of moisture
penetration.
We expressly recommend that you install a ground fault circuit interrupter
in the power supply line upstream of the condensate drain.
► Attach type B plug to the cable. Observe pin assignment (see figure).
Type B plug supply voltage
► Push plug with seal into the power adapter of the drain and screw it tight.
Make sure the seal is correctly seated!
► Install a ground fault circuit interrupter.
