the equipment.
AVERTISSEMENT : mettez le modèle 5X00 à la terre afin d’éviter tout risque de
choc électrique ou d’endommagement de l’équipement.
Ground the 5X00 at location G on the metal plate. The metal plate is attached to the
lower board assembly. Use locations E and F to ground the DO sensor ground/drain
wires - figure 3.16. (Common lettering references are used for both 5400 and 5500

In addition to grounding the 5X00, all tanks should be electrically grounded via a
ground probe.
