Wire, ground, and power up

Prerequisites

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,

using a minimum of 12 Vdc under normal operating conditions and

using 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.
