Electrical conductivity can be changed by the depositing of hindering substances and also by chemical and
mechanical influences in such a way that the permitted values laid down in the standards are exceeded. In
particular, dust, dirt and paint, acids and alkalis, overloads and impact loads can lead to the
discharge/conduction of electrical/electrostatic energy to the floor being reduced or completely interrupted.
The flooring in potentially explosive areas must be conductive and kept clean.
Because there are so many unknown factors affecting the use of our products, our guarantee with respect to
electrical conductivity relates exclusively to compliance with the permitted values laid down in the standards
for the wheels in new condition on delivery.
The user must ensure constant observation of technical safety regulations such as compliance with the
values for electrical conductivity in use. Check effectiveness at regular intervals.
9.3 Operation
in addition to section 7. For the "Operation" of Ex version equipment, the following notes apply:
Before entering an Ex zone, check the rollers for dirt and foreign bodies and clean them if necessary.
When using the drum lifter in an Ex zone, only electrically conductive drums may be used. All objects which
come into contact with the drum lifter must be electrically conductive.
When picking up containers (eg a drum from a wooden pallet) consider any static discharge and the resulting
dangers. Suitable equipotential bonding must be ensured. Ensure TRBS 2153 is observed.
Move slowly up to the drum and lift it. Ensure you keep below a speed of 1m/sec (3.6km/h).
9.4 Maintenance and repair
in addition to section 8. For the "Maintenance and repair" of Ex version equipment, the following notes apply:
Change fittings only outside of the Ex zone, eg when fitting another drum gripper. This also applies to
maintenance, cleaning and adjustment operations,
Ensure the completeness and correct fitting of all mounting and safety equipment. Check this at regular
intervals.
Ensure the equipment remains clean, especially the wheels and rollers and do not paint it.
Regularly check the bearings and grease if necessary.
When replacing parts, only use DENIOS original replacement parts. Use of unsuitable parts will lead to a
loss of ATEX suitability.
