CI-ControlWaveLP Installation / 2-15
2.4 WIRING NOTES
4 Field Wiring Terminals are located on the FMI/OB Board (see Figure 2-1).
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
connections more manageable and minimizes mechanical strain on the terminal blocks.
Signal Shielding and Grounding
The use of twisted-pair, shielded and insulated cable for I/O 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.
2.4.1 Discrete Inputs (see Figures 2-9 , 2-10 & 2-11)
A total of 16 Discrete Inputs are available. DI1-DI16 may be individually configured for dry
contact or isolated input operation. The input range is 0-24 VAC or VDC ±10% and 1
millisecond or 30 millisecond DI filtering is factory configured. Inputs are internally
sourced from the system power (12 or 24 V). DIs feature optical isolation and surge sup-
pression.
