Installation; Wiring The Transmitter - Neptune TRICON E Installation And Maintenance Manual

Chapter 3: Installing the Transmitter
Whenever possible, separate your instrumentation wiring from other wiring by using a
l
separate metal conduit or metal wire tray.
Use the minimum length of cable required for the installation and cut off any excess. Do
l
not coil excess wire.
For longer runs (maximum 1,000 feet) use #22 AWG shielded twisted pair cable for signal
connections, and tie the shield to the ground at the receiving device, not at the TRICON/E
transmitter.
When forced to cross other wiring, cross at right angles to minimize noise coupling
l
between wiring.
Use a dedicated power source, such as a separate circuit breaker or isolation transformer,
l
for all instrumentation equipment to reduce the effects of electrical noise from other
equipment on the line.
Ensure proper earth ground is available and installed in compliance with local electrical
l
codes.
