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 exclusively in compliance with the
technical data (see the "Technical data" chapter).
Possible hazards ("residual risks") can be categorized according to the following causes:
Mechanical damage
The device may be subjected to compressive forces or may be scratched during transit,
installation or commissioning, as a result of which it may no longer be leak-tight. This kind of
damage may, for example, render the device's explosion protection partially or completely
ineffective. This may result in explosions causing serious or even fatal injury.
▶
Transport the device only in its original packaging or in equivalent packaging.
▶
Observe the weight of the device.
▶
Do not place any loads 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 enclosure and seals 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.
▶
Operate the device within the prescribed operating conditions only
(see the label on the device and the "Technical data" chapter).
▶
Do not paint the device. Consult R. STAHL before mending flaws such as scratches.
▶
Devices which have a polyester powder coating must not be installed in areas containing
severely charge-producing processes.
▶
Comply with the area values specified in IEC/EN 60079-0 when affixing additional plastic
adhesive labels.
▶
Gently clean the device with a damp cloth only.
