Supply connection

NOTICE

Incorrect supply voltage

Before connecting check that the existing supply voltage matches the supply voltage specified on the label of the analyzer.

The analyzer comes with a connector (for non-heating applicances) that is only permitted to be connected to the power

supply cable by qualified personnel Qualified Personnel (Page 4). The power supply cable must comply with the valid

regulations and conditions at the place of installation and be provided with a protective conductor at the potential of the

housing. You must observe the following requirements when connecting:

● Each conductor must have a cross-section ≥1 mm

plug.

● Route the power cable separately from the signal cables.

● Provide a disconnector unit in the direct vicinity of the analyzer (for load rating, see label). This disconnector unit must be

readily accessible and marked.

Gas connections

Pipes with a diameter of 6 mm or 1/4" serve as gas inlets and outlets.

● Exception: CALOMAT 62F: Female thread 1/8"-27 NPT

The materials used must be suitable for the respective measurement.

If you wish to exit the sample gas into a common line, please observe the following points:

● The exhaust gas line must be free of rapid changes in pressure.

If this is not possible, you must either provide a separate exhaust gas line or fit a damping vessel ( > 1 l) between the

analyzer and the exhaust gas line.

● The exhaust gas line should always be routed with a downward gradient since water can condense in it.

Gas preparation

To prevent contamination of parts through which the sample gas flows, the sample gas must be prepared appropriate to the

measurement. We recommend the following minimum configuration:

● Gas sampling unit with filter

● Sample gas cooler

● Analyzer filter (approx. 1-2 μm)

Depending on the characteristics of the sample gas it may be necessary to provide additional equipment such as an external

gas suction pump, washbottle or pressure reducer.

Compact Operating Instructions in accordance with EN 61010-1 and EN 60079-0
