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.
Perform all work steps in hazardous areas with the utmost care at all times!
Transport, store, plan, mount and operate the device in compliance with the technical data
exclusively (see the "Technical data" chapter).
Possible hazards (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.
Only transport the device in special transport packaging that reliably protects the device
from external influences. Observe the ambient conditions when selecting the transport
packaging (see the "Technical data" chapter).
Do not place any load on the device.
Check the packaging and the device for damage. Report any damage to R. STAHL
immediately. Do not commission a damaged device.
Store the device in its original packaging in a dry place (with no condensation),
and make sure that it is stable and protected against the effects of vibrations and knocks.
Do not damage the device and other system components during mounting.
Excessive heating or electrostatic charge
An incorrect setup in the cabinet, operation outside of approved conditions or improper
cleaning can cause the device to heat up severely or to become electrostatically charged,
causing it to produce sparks. This may result in explosions causing serious or even fatal
injury to persons in the vicinity.
Operate the device only within the prescribed operating conditions
(see the marking on the device and the "Technical data" chapter).
Only line up or combine devices using the stipulated procedure.
Install and set up the cabinet in such a way that all devices installed within it are always
operated within the permissible temperature range (see cabinet installation guide).
Clean the device only with a damp cloth.
