WARNING!
Risk of explosion from the commissioning of
damaged products
Commissioning damaged products in areas with
potentially explosive atmospheres may lead to an
explosion. This can cause serious or even fatal
injuries as well as considerable damage to prop-
erty.
Before you install the controller, check it for
damage that could impair the movement of the
damper blade; if the controller has been dam-
aged, replace it.
Before you install the product, take suitable precau-
tions to protect air distribution components from
contamination during installation (VDI 6022). If this
is not possible, at least cover the product or take
other precautions to protect it from contamination.
In this case you have to ensure that the product
cannot be started. Ensure that all components are
clean before you install them. If necessary, clean
them thoroughly. If you have to interrupt the installa-
tion procedure, protect all openings from the
ingress of dust or moisture.
