Isolating Repeater HART Input Type 9163
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 repeater may be installed in Zone 2, Zone 22 or outside the explosion
hazard areas.
•
If installed in Zone 2, the isolating repeater is to be fitted in an enclosure that meets the
requirements of EN 50 021.
•
If installed in Zone 22, the isolating repeater is to be fitted in an enclosure that meets the
requirements of EN 50 281.
•
When used in Zone 2 or Zone 22, intrinsically safe devices of Zones 1, 0, 21 and 20 may
be connected to the intrinsically safe input circuits.
•
The isolating repeater may only be connected 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
•
The generally recognised technical regulations
•
The safety guidelines in these operating instructions
•
Any damage can invalidate the explosion protection.
Use the device in accordance with the regulations and for its intended purpose only (see
“Function”).
Incorrect or impermissible use or non-compliance with these instructions invalidates our
warranty provision.
No changes to the devices or components impairing their explosion protection are
permitted.
The device may only be fitted and used if it is in an undamaged, dry and clean state.
