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!
Possible hazards (residual risks) can be categorised according to the following causes:
Mechanical damage
The device can be compressed or scratched during transport, mounting or commissioning,
which can result in a loss of leak tightness. 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 devices
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
A defective device 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.
Connect, set up and operate the device within the prescribed operating conditions only
(see the label on the device and the "Technical data" chapter).
Install and set up the cabinet in such a way that all devices installed within it are always
operated within their permissible temperature range (see cabinet installation guide).
Comply with the maximum number of devices per enclosure/cabinet;
see the "Product selection, project engineering and modification" chapter.
Make sure that a minimum distance of 50 mm [1.96 inches] is maintained between
intrinsically safe and non-intrinsically safe circuits (IEC/EN 60079-11).
Clean the device only with a damp cloth.
