2-2 TRICON/E/E2/E3 Transmitter Installation and Maintenance Guide
• Whenever possible, separate your instrumentation wiring from other wiring
by using a separate metal conduit or metal wire tray.
• Use the minimum length of cable required for the installation, and cut off
any excess. Do not coil excess wire.
For longer runs (1000’ maximum) use #22 AWG shielded twisted pair cable for signal
connections, and tie the shield to 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 between wiring.
• Use a dedicated power source, such as a separate circuit breaker or isolation
transformer, 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 codes.
