2.7 Making Electrical Connections

This section contains instructions for making the necessary electrical connections to the flow transmitter (see Figure 16
below). The wiring between the transmitter and the transducers has been installed at the factory, and no further work is
required on this portion of the wiring.
IMPORTANT: When wires are connected to terminal blocks, use wire ties routed through the blocks, to secure them.
Attention European Customers! To meet CE Mark requirements, all cables must be installed as
described in Appendix B, CE Mark Compliance.
IMPORTANT: The meter is grounded to the electronics. This configuration must be considered when applying cathodic
protection to the pipe line. The power ground applied to the instrument should be at the cathodic
protection voltage level.
