3.3.1 Explosion Hazard

EN
Despite the device's state-of-the-art design, explosion hazards cannot be entirely eliminated
EN
in hazardous areas.
EN
 Perform all work steps in hazardous areas with the utmost care at all times!
EN
EN
Possible hazards ("residual risks") can be categorised according to the following causes:
EN
Mechanical damage
EN
The device can become damaged during transportation, mounting or commissioning
EN
and develop leaks as a result. This kind of damage can, for example, render the device's
EN
explosion protection partially or completely ineffective. This may result in explosions causing
serious or even fatal injuries to persons in the vicinity.
EN
 Transport the device only in its original packaging or in equivalent packaging.
EN
 Do not place any load on the device.
 Check the packaging and the device for damage. Report any damage to R. STAHL
EN
immediately. Do not commission a damaged device.
EN
 Do not damage the device and other system components during mounting.
EN
Excessive heating or electrostatic charge
EN
An incorrect setup in the cabinet, operation outside of approved conditions or improper
EN
cleaning can cause the device to heat up severely or to become electrostatically charged,
EN
causing it to produce sparks. This may result in explosions causing serious or even fatal
injuries to persons in the vicinity.
EN
 Connect, set up and operate the device within the prescribed operating conditions only
EN
(see the label on the device and the "Technical data" chapter).
EN  Select conductor cross-sections that can comply with the required current carrying
capacity.
