3.3 Connection instructions
3.3.1 Assignment of terminals
3.3.2 Mains connection
● Wiring must be carried out exclusively by specialists who are familiar with
the valid local regulations for setting up power installation rated for up to
1000 volts.
● Check whether the voltage of the mains corresponds to that on the rating
plates of the equipment and gas sampling hose.
● All cables that are used must be selected in accordance with DIN/VDE or
the relevant national regulations.
● Install an all-pole switch near the equipment to switch the equipment on
and off.
● Run the mains cable through the (anti-kink) cable gland on the right.
● Connect the mains voltage cable to terminals 27 (L), 28 (N) and 29 (PE).
● Do not disconnect the yellow/green protective earth conductors or those
labelled „PE“ at any point.
● Wire all power consumers within a complex system, including the
protective earth conductors, in a star connection. Avoid sequential wiring.
● Under no circumstances use the unit’s supply terminals as a terminal for
other loads.
● In the case of interference-prone power supplies, it is a good idea to
connect an isolating transformer on line side, and also a mains filter if
required.
● If there are several units in one system, each must be protected
separately against short circuits and equipped with a disconnector.
● When the work is finished, tighten the threaded joints on the cable
glands. This ensures that the degree of protection is observed and
provides strain relief.
● Check that the protective earth conductor is connected correctly.
