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 frequency transmitter may be installed in Zone 2, Zone 22 or outside of the
hazardous area.
• If installed in Zone 2, the frequency transmitter is to be fitted in an enclosure that which
meets the requirements of EN 50 021.
• If installed in Zone 22, the frequency transmitter is to be fitted in an enclosure that which
meets the requirements of EN 50 281.
• If installed in Zone 2 and Zone 22, devices connected to the intrinsically safe input
circuits of Zones 1, 0, 21 and 20 may be connected.
• The frequency transmitter may only be connected to devices which will not be subjected
to voltages higher than AC 250 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.
• Generally recognised technical regulations.
• Safety guidelines in these operating instructions.
• Any damage can compromise and even neutralise the explosion protection.
Use the device in accordance with the regulations and for its intended purpose only (see
"Function").
Incorrect or non-permissible deployment and/or non-compliance with the instructions of this
operating manual shall invalidate any warranty by us.
No changes to the devices or components impairing their explosion protection are
permitted.
Further, the device may only be fitted if it is undamaged, dry and clean.
