②CCI can accept analog signal input and the jumper can be used to select voltage input (0~10V) and current input
(0/4~20mA). The wiring is shown below:

2. Wiring connections analog output terminal
If the analog output terminals AO1 and AO2 are connected to analog meters, then various kinds of physical values can
be indicated. The jumper can select current output (0/4~20mA) and voltage output(0/2~10V). The wiring is shown in
Fig.3-16..

Notes:
(1) When using analog input, a common mode inductor can be installed between VCI and GND or CCI and GND.
(2) Analog input and output signals are easily disturbed by noise, so shielded cables must be used to transmit these signals and
the cable length should be as short as possible.
3. Wiring of Serial Communication Port
Wire connections of serial communication port.
EV2000 drive provides two kinds of serial ports: RS232 and RS485 which can be selected by Jumper CN14.
Wire as following figures show, and a “single-master single slave” system or a “single-master multi-slaves” system can
be formed. The drives in the network can be monitored and controlled remotely and automatically in real time by using a
PC or PLC controller. Thus more complicated operation control can be realized (e.g. Unlimited multi-step PLC
operation).
① The drive connects to the host via its RS232 port:
