Terminal Connections
The ControlWaveLP uses compression-type terminals that accommodate up to #16 AWG
wire. A connection is made by inserting the wire’s bared end into the clamp beneath the
screw and securing the screw. The wire should be inserted fully so that no bare wires are
exposed to cause shorts. If using standard wire, tin the bare end with solder to prevent
flattening and improve conductivity.
Allow some slack in the wires when making terminal connections. The slack makes the con-
nections more manageable and minimizes mechanical strain on the terminal blocks.
Signal Shielding and Grounding
The use of twisted-pair, shielded and insulated cable for analog output signal wiring will
minimize signal errors caused by electromagnetic interference (EMI), radio frequency
interference (RFI) and transients. When using shielded cable, all shields should only be
grounded at one point in the appropriate system. This is necessary to prevent circulating
ground current loops that can cause signal errors.
