3.2 Startup, installation
The devices are intended for installation in a higher-level system. The intervals for
cleaning the operating resources (dust deposits) are specified depending on the
degree of IP protection. It is extremely important to ensure that only devices with
suitable ignition protection for the zones/categories are installed! It is essential that
the installation regulations applicable at the national level, e.g. EN 60079-14, are
adhered to during installation. Other important factors:

In the event of adverse environmental conditions, it is necessary to ensure
that the devices are accordingly protected.

Follow the operating instructions for the respective device and adhere to any
special conditions described there.

The device may only be used for the purpose for which it was intended.

It is essential to avoid electrostatic charges.

Any possible metal parts in the device/lines (e.g. shielding) must be
incorporated in the potential equalization PA in compliance with the user’s
country regulations.

Parts that have jammed (e.g. as the result of frost or corrosion) may not be
loosened by force in hazardous atmospheres.

Operate the device only in the completely assembled state and enclosed in
undamaged housing. Operating with a damaged housing is prohibited.

At ambient temperatures of less than -5°C the connecting lines must be
securely laid.

Do not allow the outside of the device to come into contact with strongly
corrosive media.

Do not subject the system to excessive vibrations, bending or torsion.

The devices may not – or only with the manufacturer's permission, and then
only using special measures – be used in systems with electric corrosion
protection. Parasitic currents must not be fed in via the shielding.

Installations in Ex areas may be carried out only in compliance with the local
installation regulations.

Installation and maintenance only in ex-free atmospheres in compliance with
the user’s national regulations.
Additional precautionary measures must be taken if there is a possibility that
hydrogen sulfide, ethylene oxide and/or carbon monoxide could be present. These
compounds have very low ignition power!
Only non-arcing tools may be used for these compounds as well as all compounds
included in explosion group IIC – if explosive atmospheres are still to be expected!
3.3 Application
The devices may be used only in the correct way and for the intended purpose in a
normal industrial environment. Use for unsuitable purposes, will render all
guarantees and liability of the manufacturer void!
