2.10 First commissioning / Commissioning
Prior to the first commissioning the equipment is to be checked regarding its suitability
in the respective zone according to its labeling. The values indicated on the name-
plate are not to be exceeded. With use of the equipment in areas which are potentially
explosive because of dust, a deposit of dust on the top-side of the equipment shall be
avoided. Here the installation of an additional covering may be required in circum-
stances where the deposit of dust cannot be reliably avoided.
The operational safety of the equipment and the correct functional arrangement of the
equipment inside the plant must be checked before commissioning. It may only be
used in a clean and undamaged condition.
2.11 Assembly, installation and dismantling
With installation and operation of the explosion protective equipment, one should con-
sider protection against hazardous environmental influences which limit the intended
use of the equipment. This could be protection against aggressive fluids or weather
protection for example. During installation, the EN/IEC 60079-14 as well as other na-
tional standards and regulations applicable at the installation site are to be adhered to.
The information on the nameplate and in the type examination certificate must be
complied with.
The assembly of the equipment takes place according to the enclosure's established
mounting possibilities, but impacts on the shaft such as from hammer blows are to be
avoided.
When bolts are screwed into the drilled blind holes, at least one thread winding is to
remain free at the drill base.
When the equipment is connected, the cleavage surfaces shall not be damaged, the
O-ring must be present and may not have any signs of wear, also see Figure 13 on
page 35.
If cable inlets or dummy plugs are mounted, the threads may not be damaged. In par-
ticular, the cable inlet must be suitable for the required cable diameter. The used ca-
ble inlets respectively dummy plugs must have the igniting type of protection "d" for
flameproof encapsulation.
In potentially explosive areas the connection lines are to be routed in such a way that
they are protected from damage and mechanical failure. The individual wires must not
be damaged. The maximum connection information on the nameplate and also the
references in chapter
“ Special conditions for safe use, marking "X" ” on page 18 are
to be observed.
For metal enclosures in potentially explosive areas an equipotential line with at least
4 mm
2
is required.
