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.

• Lay the pre-installed cabling in the intended electrical connections – see figure.
DANGER
Explosion hazard due to insufficient protective measures!
Non-compliance results in severe or fatal injuries.
• Select suitable conductors to ensure that the maximum permissible
conductor temperatures are not exceeded.
• When using core end sleeves, attach them using a suitable tool.
• The conductor insulation must be touching the terminal.
• Do not damage the conductor (e.g. nicking) when stripping it.
• Finally, check the conductor to ensure that it is secure (fixed).
