5) Special Conditions for Safe Use
Special Condition for safe Use as stated on the Type
Examination Certificate DEMKO 14 ATEX 4786493904X / CoC
IECEx ULD 14.0004X /
UL21UKEX2131X:
When used for a Group III application, the surface of the
enclosure may store electrostatic charge and become a source
of ignition in applications with a low relative humidity <~30%
relative humidity where the surface is relatively free of surface
contamination such as dirt, dust, or oil.
Guidance on protection against the risk of ignition due to
electrostatic discharge can be found in EN TR50404 and IEC
TR60079-32.
End user shall adhere to the manufacturer’s installation and
instruction when performing housekeeping to avoid the potential
for hazardous electrostatic charges during cleaning, by using a
damp cloth.
To maintain the ingress protection rating and mode of
protection, the cable entries must be fitted with suitably rated,
certified cable entry and/or blanking devices during installation.
6) Product Mounting and Access
6.1. Location and Mounting
The location of the combined alarm horn and beacon should be
made with due regard to the area over which the warning signal
must be visible and audible. It should only be fixed to services
that can carry the weight of the unit.
DxC2 Alarm Horn and Strobe to a flat surface via the two 9.7 x
6.7mm, 147mm pitch fixing holes in the mounting feet of the
sounder section and the two 7mm fixing holes in the feet of the
base.
The equipment is not to be mounted with the horn facing
upwards.
