3.3 Residual Risks
3.3.1 Explosion Hazard
Despite the device's state-of-the-art design, explosion hazards cannot be entirely eliminated
in hazardous areas.

Possible moments of danger (residual risks) can be categorised according to the following
causes:
Mechanical damage
The device can be damaged during transport, mounting or commissioning.
This kind of damage can, for example, render the device's explosion protection partially or
fully ineffective. This may result in explosions causing serious or even fatal injury to persons
in the vicinity.

in a cabinet with a suitable degree of protection in accordance with IEC/EN 60079-0.

An enclosure with at least an IP54 protection rating is required for use in Zone 1 and
Zone 21, as well as in safe areas.
