Potential-free contact
Connection to the dust extractor system:
The unit can be connected via the potential-free contact
as follows:
• Cut the wires to the same length.
• Insert into the holes 1 and 2 and push the plugs to-
gether.
• Screw on the plug‘s thumb screw.
• The wires are automatically electrically connected via
an insulation displacement connector.

Potential-free contact
• In addition, the vacuum performance must be sufficient
to achieve the required negative pressures and an air
speed of 20 m/s at the connector. (see “Technical
data”)
• Check the air speed before putting the machine into
operation for the first time and after essential changes.
• The dust extractor setup must be controlled before the
machine is put into operation for the first time. Check for
obvious defects on a daily basis and the efficiency on a
monthly basis.
• The dust extractor must be connected to the machine
in such a manner that it runs in unison with the
machine.
• The dust extraction hoses must be electrically conduc-
tive and grounded to prevent electrostatic
build up.
• Use dust extractors with reduced dust emission to clean
dust from the machine.
Note: As a rule, all units must be vacuumed during use. A time delayed socket is available as an accessory.
Warning! Risk of injury! The dust extraction hose must be non-flammable and must not conduct electricity! For
this reason, only use genuine FELDER dust extraction hoses!
