
It is essential to observe the applicable regulations, plant-specific
provisions and the requirements for the test personnel.

Installation, commissioning and recurring tests may only be
carried out by suitably qualified personnel (competent person).

Compliance with the following important explosion protection
characteristics must be evident from the marking on the product:
– G = Gas, D = Dust; M = Mining
– Thruster category 1,2,3 in the 3 zone areas
– Gas characteristic values:
– Dust characteristic values:

For work such as assembly, electrical connection, repair or
opening the housing, it must be ensured that
– no explosive atmosphere is present.
– no electrical voltage is present.
– inadvertent switching on is not possible.

Dust deposits on EdEx thrusters must be avoided so no
dangerous temperature increase arises on the surface.

Clean non-conductive parts (e.g. plastic) using only a damp cloth

Ensure that all technical and organisational protective measures
are fulfilled and their function/effect is tested.

Modifications to the EdEx thrusters are not permitted and can
cause an explosion hazard (ignition).

The contents of the EU type examination certificate must be
observed. If there is an X after the number on the EC type
examination certificate, special conditions or deviations from the
standard conditions apply. These special notes must therefore
be checked in the certificate.

Before any activities (e.g. assembly) are carried out in potentially
explosive areas, the operating company must issue approval for
the work.
