Rewire from 7835/7845 Advanced electronics meter
To wire from an existing 7835/7845 meter with Advanced electronics, you must have
purchased one of the following CDM transmitter versions:
•
Analog
•
Time Period Signal (TPS)
•
Any option with Modbus/RS-485
•
Processor for remote-mount 2700 FOUNDATION

fieldbus
Procedure
See the following for information on the terminal-to-output relationships from the
7835/7845 to the CDM.
Important
Depending on whether you are wiring in an explosion proof/flameproof or intrinsically safe area, see
the additional information documented for these types of installations.
