Analog Signal Wiring Guidelines
Proper grounding and wiring of all electrical equipment is important to help ensure optimum
operation of your system and to provide additional electrical noise protection for your
application. Please follow these guidelines for your analog signal wiring:
The ground connections of the DC power controller(s) and the analog signal processing
equipment (e.g. PLC module, panel meter, etc.) should be connected to the earth ground
of the system.
All ground wires should be as short as possible.
Always use shielded twisted-pair cables for analog signals.
Connect only one end of the cable shield to earth ground.
Keep cable length as short as possible.
Keep signal wires as far away as possible from AC wires and rapidly switched DC wires.
Place them in separate wire trays or ducts.
Follow other system grounding and wiring guidelines found in the manual of your analog
signal processing equipment.
If possible, use analog signal metering devices with differential inputs for improved noise
immunity.

Control of DC Output Current
It is necessary to provide a command signal to control the DC output current to the CEDI
module.
Use
only one
of the following options to control the DC output current:
1. Ionpure® G2 display board, Model No. IP-POWERDSP-G2, which can operate
up to
sixteen
power controllers. Use standard Cat 6 cables, Ionpure
model numbers IP-
CABLE50CM-G2 or IP-CABLE2M-G2.
2. Ionpure® single-channel display board, Model No. IP-DSP1 or IP-DSP1P, which can
operate
one
power controller. Use Ionpure® cables model number IP-LXCABLE06, IP-
LXCABLE10 or IP-LXCABLE16 only.
3. Ionpure® eight-channel display board, Model No. IP-DSP8 or IP-DSP8P, which can
operate
up to eight
power controllers. Use Ionpure® cables model number IP-
LXCABLE06, IP-LXCABLE10 or IP-LXCABLE16 only.
4.
A 0 to 5 VDC input signal from a remote process controller, such as a PLC. Connect
the control signal as follows (see Figure 6):
