FG-200 HSE/FF Modbus - User Manual
12
Version EN-112021-1.30.3
§
In explosion group IIC and Zone 2 no protected plastic surfaces > 20 cm
2
are allowed; in IIB or dust-Ex,
100 cm 2 may be reached.
§
The hazard of any objects falling onto the bus-module must be prevented.
§
The FG-200 does not meet the requirements of impact protection and IP54 (according to IEC 60529).
It must be installed in a protective enclosure which meets the requirements for resistance to impact
and IP as stated in section 26.4 of IEC/EN 60079-0. This enclosure must be fully mounted and intact. If
the enclosure is damaged, the operation is not permitted.
§
Transient protection must be provided at a level not exceeding 140% of the peak rated voltage value
at the supply terminals to the equipment.
§
When removing the packaging ensure that no dirt can enter the enclosure or the plugs.
§
If any vibration during the operation may cause parts of the plugs to loosen, then the plugs have to be
provided with a light firm varnish used for securing screws. An extraction force of 0.5 Nm has to be
achieved at an equivalent thread.
§
To circuits of Zone 2 only such equipment may be connected that is suitable for operation in this zone
and has been certified accordingly.
§
Components may only be replaced by original spare parts which are also approved for the use in Ex-
atmospheres. Spare parts are ordered as complete units giving the material number stated on the
device (marking, type label).
§
Only such auxiliary components may be used in potentially explosive atmospheres which meet all
requirements of European and national directives and legislation.
§
The environmental conditions specified in the manual have to be followed strictly.
§
The FG-200 is not to be used in systems where cathodic systems for corrosion protection are in place.
Although special precautions may allow the use in such systems (additional earthing bridges), the
manufacturer has to be consulted in each case.
§
The operator has to provide measures for protection against lightning.
§
According to the local conditions and in compliance with the environmental rules, the operator is
responsible to visually inspect the system and to remove dust settlements in a regularly interval (every
6 months).
§
The company installing the device has to ensure that the transient characteristic is limited to 40%
above the service voltage.
§
Additional precautions have to be taken, if the presence of hydrosulfide, ethylene oxide and/or
carbon monoxide is to be expected: those substances are of a vary low ignition energy.
§
Icing is not permitted.
