1 Safety instructions

The most important safety instructions are summarised in this chapter. It is intended to
supplement the relevant regulations which must be studied by the personnel responsible.
When working in hazardous areas, the safety of personnel and plant depends on
complying with all relevant safety regulations. Assembly and maintenance staff working on
installations therefore have a particular responsibility. The precondition for this is an
accurate knowledge of the applicable regulations and provisions.
When installing and operating the device, the following are to be observed:
•
The national installation and assembly regulations (e.g. EN 60079-14) apply.
•
The isolating power Supply may be installed in Zone 2, Zone 22 or outside the
explosion hazard areas.
•
In the case of operation in Zone 2, the transmitter power supply unit must be fitted in
an enclosure which complies with the requirements of EN 60079-15.
•
In the case of operation in Zone 22, the transmitter power supply unit must be fitted in
an enclosure which complies with the requirements of EN 61241-1.
•
When used in Zone 2 and Zone 22, intrinsically safe devices of Zones 1, 0, 21 and 20
may be connected to the intrinsically safe input circuits.
•
The transmitter power supply unit may only be connected to devices which will not be
subjected to voltages higher than AC 253 V (50 Hz).
•
The safe maximum values of the connected field device(s) must correspond to the
values of the data sheet or the EC-type examination certificate.
•
Interconnecting several active devices in an intrinsic safety circuit may result in other
safe maximum values. This could endanger the intrinsic safety!
•
National safety and accident prevention regulations
•
The generally recognised technical regulations
•
The safety guidelines in these operating instructions
