Warning
Proper handling of the equipment by qualified personnel with observance of the
8 8 8 8
warnings is a prerequisite for safe operation.
The regulations for installation of electrical systems in hazardous areas according to
DIN VDE 0165 (EN 60079-14) and the standards therein must be observed. Failure
to do so can lead to considerable damage, serious injury or even death.
- A mains circuit-breaker must be provided in the building installation.
- The housing of the analyzer must be connected to a potential equalizer (see also the appropriate
manual).
- Solid or stranded cables with a cross-section up to 2.5 mm² can be used for wiring the terminals.
- End ferrules must be fitted to all stranded wires.
- All connecting leads must be kept short inside the device.
- Intrinsically-safe lines must be labelled and laid separately from non-intrinsically-safe lines, keeping
the necessary minimum distances apart.
- Power supply and signal lines must be connected according to the terminal wiring plans of the
devices to be connected (see the appropriate manuals).
- Special care must be taken for the cable inlets (PG screwed glands). Sealing rings corresponding to
the cable diameter must be inserted for cable glands. Cable diameter ranges and torques (M) for the
PG screwed glands:
- PG 13.5:
- PG 16:

Inputs and outputs

The analog inputs and outputs of the analyzers are not intrinsically-safe in the standard version.
All non-intrinsically-safe inputs and outputs must be wired via Ex-coupling relays so that no external
voltages are produced when the purging gas in the device fails.
Additional Ex isolating components can be mounted on the rail in the analyzer (see also Section 5).
These additional devices must be agreed upon with the Ex specialist responsible.
