Preparing to Wire Signals

This section provides information about wiring signals to a DT9812, DT9813, or DT9814 Series
module.

Wiring Recommendations

Keep the following recommendations in mind when wiring signals to a DT9812, DT9813, or
DT9814 Series module:
• Follow standard ESD procedures when wiring signals to the module.
• Use individually shielded twisted-pair wire (size 16 to 26 AWG) in highly noisy electrical
environments.
• Separate power and signal lines by using physically different wiring paths or conduits.
• To avoid noise, do not locate the box and cabling next to sources that produce high
electromagnetic fields, such as large electric motors, power lines, solenoids, and electric
arcs, unless the signals are enclosed in a mumetal shield.
• Prevent electrostatic discharge to the I/O while the box is operational.
• Connect all unused analog input channels to analog ground.
