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 resistance isolator may be installed in Zone 2, Zone 22 or outside of the hazardous
area.

If installed in Zone 2, the resistance isolator is to be fitted in an enclosure that which
meets the requirements of EN 60079-15.

If installed in Zone 22, the resistance isolator is to be fitted in an enclosure that which
meets the requirements of EN 61241-1.

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 resistance isolator 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!

ATTENTION: electrostatic sensitive components. Unload yourself at grounded metal
parts or use an ESD-wristband before working with the resistance isolator.

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.
