2.6 Connect wiring and power up
Use copper wire of sufficient size to ensure that the voltage across the
transmitter power terminals does not drop below 9 Vdc. Power supply
voltage can be variable, especially under abnormal conditions, such as when
operating on battery backup. Emerson recommends a minimum of 12 Vdc
under normal operating conditions and shielded twisted pair Type A cable.
Procedure
1. To power the transmitter, connect the power leads to the terminals
indicated on the terminal block label.
