Electrical installation
Before starting work, make sure that you observe and follow all the information in Chapter
and warning
information. A functioning effective lightning protection must exist at the place of use
and an external switch-off device must be installed near the device by the system operator. Above
all, the following sections are important:
Always observe the general safety rules, especially in potentially explosive atmospheres. Always use
a gas detector when working on the instrument and make sure that the GasLab Q2 is voltage-free
(supply and signals) before any change of the wiring. The local / national installation guidelines (e.g.
EN 60079-14) must be observed for all work. The device must be connected to the equipotential
bonding or earth at the place of use.
The explosion protection is lost if the cable glands are installed incorrectly, the installation
is explosion safety relevant! Make sure that the installation is safe and correct. The
manufacturer therefore only accepts responsibility for cable glands made by him or on his
behalf.
La protection contre les explosions est perdue si les presse-étoupes sont mal
installés, l'installation est importante pour la sécurité contre les explosions ! Veillez à ce
que l'installation soit sûre et correcte. Le fabricant n'assume donc la responsabilité que
pour les presse-étoupes fabriqués par lui ou en son nom.
It is essential that you follow the instructions in the following sections.
