7.2 Mounting/dismounting, operating position
DANGER
Explosion hazard due to improper mounting!
Non-compliance results in severe or fatal injuries.
• Only operate the device if it is not damaged.
If the thread is damaged, replace the device immediately.
• Only install the device in a clean and dry operating environment.
• Only mount the device on a wall or on a suitable surface.
• Carefully protect exposed joint surfaces from damage, dust and dirt.
• Install end flanges without applying force (without hammer and tool)
in straight alignment.
• If necessary, fit core end sleeves gas-tight and using a suitable tool.
DANGER
Explosion hazard due to electrostatic discharge!
Non-compliance results in severe or fatal injuries.
Do not use the device in strong charge-generating environments!
The following processes/activities should be avoided:
• Accidental friction
• Particle flows
DANGER
Explosion hazard due to open drilled holes, unused cable entries and cable
glands!
Non-compliance results in severe or fatal injuries.
• Only use cable entries and stopping plugs that have been separately
checked and certified in accordance with Directive 2014/34/EU (ATEX)
and IECEx (CoC), and which technically correspond to the state of
technology given in the certificate.
• The IP level of protection of the cable entries and stopping plugs
must at least correspond to the IP level of protection of the device
(see marking on the device).
• When selecting cable entries, observe the type of thread and thread
size in the component documentation.
• Seal the thread with non-curing thread sealant in order to guarantee the
IP66 degree of protection.
• Always close unused drilled holes, cable entries and cable glands using
approved stopping plugs or plugs. Observe IEC/EN 60079-14 for this.
• Installation of the cable gland must be performed in accordance with the
manufacturer's instructions.
• The cable entry temperature may exceed 70 °C.

• Select a mounting location that is suitable for the signal effect of the device, as well as
the required mounting and installation parameters (see "Technical data" chapter).
• Mount the device on a flat surface using the L-bracket and screw holes.
• Mount suitable approved electrical lines (see "Technical data" chapter) using a
suitable flameproof cable entry.
• Close unused entries using certified, flameproof stopping plugs.
NOTICE
Malfunction or device damage from electrostatic discharge.
Electronic components can be destroyed if touched.
Non-compliance may lead to material damage!
• Do not touch the LED PCBs!

The figure depicts the xenon flash tube variant for the FX15.
The upper PCB components of the LED variant are different to the xenon
variant.
However, the fundamental structure of both products is the same.
22937E00
• Loosen the 6 cheese-head screws
(6/TX20).
22939E00
• Carefully remove the top part (5)
by removing the connector from the
connection PCB.
• Set the top part (5) aside.
