2.9 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
nameplate 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 which is more
than 2 mm thick is not permissible. Here the installation of an additional covering may
be required in circumstances 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.
2.10 Assembly, installation and dismantling
With installation and operation of the explosion protective equipment, one should
consider 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 IEC 60079-14 and
DIN EN 60079-14 as well as other national standards and regulations applicable at
the installation site are to be adhered to.
The information on the nameplate must be complied with.
The assembly of the equipment takes place according to the enclosure's established
mounting possibilities, but impacts on the equipment such as from hammer blows are
to be avoided. Do not bend the sensor rod and do not install the equipment next to
magnetic fields.
In potentially explosive areas, the equipment's power supply line with mating
connector respectively the connection cable is to be routed in such a way that it is
protected from damage and mechanical failure. In case of connection cables without
mating connectors the single wires mustn´t be damaged. The maximum connection
information on the nameplate must be complied with.
Observe the information in chapter “ Special conditions for safe use, marking "X" ” on
page 16.
For metal enclosures in potentially explosive areas an equipotential line with at least
4 mm
2
is required.
Wiring work, opening and closing of electrical connections may only be performed
with the power switched off.
Do not perform any welding work once the equipment has already been wired and
switched on.
Touching the equipment-connection contacts with bare hands is to be avoided, or
the respective ESD-protective measures are to be implemented.
