Installation must be carried out in compliance with the latest
issue of the following standards:
EN60079-14 / IEC60079-14: Explosive atmospheres -
Electrical installations design, selection and erection
EN60079-10-1 / IEC60079-10-1: Explosive atmospheres -
Classification of areas. Explosive gas atmospheres
EN60079-10-2 / IEC60079-10-2: Explosive atmospheres –
Classification of areas. Explosive dust atmospheres
5) Special Conditions of Use
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.
Equipment with the flare horn shall not be installed with the
flare higher than horizontal (to avoid accumulation of dust).
The equipment incorporates metal parts isolated from earth,
having capacitance values exceeding the limits permitted in
the standards of certification. Mounting bracket – 10.33pF.
6) Product Mounting and Access
6.1.
Location and Mounting
The location of the loudspeaker should be made with due
regard to the area over which the warning signal must be
audible. They should only be fixed to services that can carry
the weight of the unit.
The E2x loudspeaker should be secured to any flat surface
using the three 7mm fixing holes on the stainless steel U
shaped mounting bracket. See Figure 1. The required angle
can be achieved by loosening the two large bracket screws in
the side of the unit, which allow adjustment of the
loudspeaker in steps of 18°. On completion of the installation
the two large bracket adjustment screws on the side of the
unit must be fully tightened to ensure that the unit cannot
move in service.
