WARNING
Electrocution hazard
Installation must be done by trained staff only.
CAUTION
Wrong mains voltage may destroy the device.
Regard the correct mains voltage as given on the type plate.
Make sure that the mains cable is laid out stress free.
WARNING
Damage to the device in case of insulation testing
Do not proceed insulation tests with high voltage to the device as a whole.
The device is equipped with extensive EMC protection. If insulation tests are carried out the electronic filter
devices will be damaged. All necessary tests have been carried out for all concerned groups of components
at the factory (test voltage 1 kV or 1.5 kV respectively, depending on the device).
If you intend to carry out insulation test by yourself, make sure to carry them out for the respective
component only.
Disconnect the heating (see wiring diagram in the annex). Now you may carry out the insulation test to
protective earth.
WARNING
Fire hazard / gas leakage
Damage of the probe when heated up above 280 °C (536 °F)
If the sample gas probe is heated above 280 °C (536 °F) gaskets, cables
and heat insulation may be damaged. This may lead to gas leakage or
outbreak of fire.
The sample gas tube shall not be heated to temperatures > 280 °C (536 °F).
With a maximum ambient temperature of 45 °C (113 °F) , the sample gas probe may be heated up to
280 °C (536 °F) . If the temperature exceeds 300 °C (572 °F), the built-in controller switches the probe off
immediately (=> no heating). The display s
hows “Error”. In this case, the sample gas tube has to be put out
of order and has to be sent to the manufacturer for maintenance.
These tubes are equipped with a controlled and adjustable heating. The controller is not part of the delivery.
It is supplied with 115 V AC, 50/60 Hz or 230 V AC, 50/60 Hz as given on the type plate.
When adjusting the external temperature controller, make sure that the maximum operating temperature of
280 °C (536 °F) is not exceeded.
If - due to the application - the sample gas probe is exposed to high heat radiation, a suitable shielding has
to be installed to protect the probe.
