3.6.3 Analog input output terminal wiring
(1) CCI terminals accept analog voltage signal input, input voltage(0-10V), input
current(0-20mA). Wiring as follow:
Fig.3-8 CCI terminal wiring diagram
3.6.4 Communication terminal wiring
EDS300 inverter provides 485 serial communication interface for the user.
Following wiring methods make single-main single-sub control system or
single-main multi-sub control system possible. Using upper machine(PC or PLC
controller) software can realize real time supervision to inverter in the industrial
control system so that realize complicated run control such as long-distance control,
high automatization etc; you can also use one inverter as mainframe and the others
as submachine to form cascade or synchronous control network.
(1) When inverter 485 interface connected to other devices with 485 interface,
you can connect wire as below figure.
Fig.3-9 communication terminal wiring
(2) To connect remote control keypad, you can connect plug of remote control
keypad to RS485 directly. No need to set any parameter
,
inverter local keypad and
remote control keypad can work at the same time.
(3) Connection between inverter RS485 interface and upper machine (with
RS232 interface):

(1) When input analog signal
,
can connect filter capacitor or common module
inductance between CCI and GND.
(2) Analog input, output signal is easy to be disturbed
,
so must use shielded cable
when wiring and well grounded, wiring length should be as short as possible.
