3.3.1 Explosion Hazard

Explosion hazards cannot be entirely eliminated in hazardous areas.
US
US
 Perform all activities in hazardous areas with the utmost care at all times!
US
Possible hazards ("residual risks") can be categorized according to their cause:
US
US
Damage to the device
The device may be warped, dented or scratched during transport, mounting or
US
commissioning. This can cause it to no longer be leak-tight. A lack of leak-tightness can
US
render the device's explosion protection partially or completely ineffective.
US
This may result in explosions causing serious or fatal injuries to persons.
To prevent this, comply with the following safety measures:
US
 Before transport or mounting, determine the weight of the device – see specifications on
US
the packaging.
 Only use transport and lifting equipment that can reliably bear the size and weight of the
US
device.
US
 Transport the device only in its original packaging or in equivalent packaging.
US
 Check the packaging and the device for damage. Report any damage to R. STAHL
immediately.
US
 Store the device in its original packaging in a dry place (with no condensation), and make
US
sure that it is stable and protected against the effects of vibrations and knocks.
US
 Do not damage the enclosure, built-in components and seals during mounting.
US
Too much heating or electrostatic charge
US
A subsequent conversion or painting can change the state of the device in such a way that it
US
is no longer explosion-protected. Improper cleaning can also cause the device to heat up
severely or become electrostatically charged. This can cause sparks. This may result in
US
explosions causing serious or fatal injuries to persons. To prevent this, comply with the
US
following safety measures:
 Commission the device within the prescribed operating conditions only
US
(see the label on the device and the "Technical data" chapter).
 Only have the device painted or coated by the manufacturer.
 Do not have the paintwork touched up by anyone other than the manufacturer.
 We recommend providing a protective roof or wall for any device that is operated outdoors
or exposed to weathering.
 Regularly inspect the device for a material change (plastic).
 If any changes are identified, test or replace the device.
 Only attach additional adhesive labels made of plastic according to the surface
specifications in UL 60079-0.
 Observe the maximum number of conductors (see chapter 5.3).
 Terminals can be added within the physical limits of the enclosure (see catalogue)
and the thermal limits as explained in chapter 5.3.1.
 Wires/cables shall be rated for min. 75 °C/167 °F.
