● A functional test should always be carried out with a connected / producing machine tool. Check
if the collection of the fume or dust is sufficient. (Visual inspection).
16.2.5. Electrical test of the electrical lines and earthing connections
Danger arising from electricity.
The operator is responsible for ensuring that all work on electric components is carried out
by authorised and qualified personnel.
The device is subject to regular electrical checks by the operator of the device, and are subject to
national standards of the different countries.
The here recommended maintenance interval complies with the in Germany applying "Regulation 3 of
the German Social Accident Insurance - Electrical plants and equipment" (formerly known as BGV-A3).
The check must only be carried out by a qualified electrician or a person trained in electrics using
suitable measuring and test devices. The scope of testing and the methods must be in line with the
respective national standard. All contacts in the control cabinet must be checked for tight fit, and must
be readjusted if necessary.
The conductivity (<10^6 Ohm) of all parts that come into contact with dust (housing, suction pipe, filter
cartridges, solenoid valves, etc.) must be checked annually using suitable measurement and test
equipment. To do this, use the preprinted measurement report in Annex A.
16.2.6. Test of fixing of the mounted unit elements
The following steps must be carried out in the course of the inspection:
● Make sure that all elements that are connected at or with the unit are firmly fixed in place and
have not come undone or loose. These also include all air-carrying lines, all extraction
elements, bearing structures and frames.
● In the case of unit elements which are subject to vibrations and/or movements, the operator
may need to define a shorter maintenance interval.
