Connecting the Discovery TGA to the Controller
To connect the TGA system, you will need access to the Discovery TGA instrument’s back panel.
NOTE
: Connect all cables before connecting the power cord to an outlet.
CAUTION: Whenever plugging or unplugging power cords, handle them by the plugs, not by the
cords.
MISE EN GARDE: Chaque fois que vous branchez ou débranchez les cordons d'alimentation,
tenez-les par les fiches et non par les cordons.
The Discovery TGA back panel has fifteen ports; the table below provides a description of the function of
each port.
WARNING: Protect power and communications cable paths. Do not create tripping hazards by
laying the cables across access ways.
AVERTISSEMENT: Protégez les chemins de câble électriques et de câbles de télécommunica-
tion. Ne créez pas de risques de déclenchement en posant des câbles sur les voies d'accès.
