Mounting
Before you begin, note that:
▪The mounting panel cannot be more than 5 mm thick
▪To minimize electromagnetic interference, mount the controller on a metal panel and
earth the power supply according to the details on page 6.
1. Make a panel cut-out that suits your model controller.

2. If you mount the controller on a metal panel, earth the power supply only in
V230:
a. Bore a hole to suit the NC6-32 screw supplied with the kit.
b. Scrape panel paint away from the contact area to ensure a conductive connection.
c. Drive the screw into the hole.
d. Place the following hardware screw’s shank, in the order shown in the
accompanying figure: washer, ring cable shoe, second washer, spring, and nut.
▪Pay Attention:
The wire used to earth the power supply must not exceed 10 cm in length
if your conditions do not permit this, do not earth the power supply.
▪Make sure that the metal panel is properly earthed.
3. Slide the controller into the cut-out, ensuring
that the rubber seal is in place.
4. Push the 4 mounting brackets into their slots
on the sides of the controller as shown in the
figure to the right.
5. Tighten the bracket screws against the
panel. Hold the bracket securely against the
unit while tightening the screw.
6. When properly mounted, the controller is squarely situated in the panel cut-out as shown below.
Wiring: General
▪This equipment is designed to operate only in SELV/PELV/Class 2/Limited Power
environments
▪All power supplies in the system must include double insulation. Power supply outputs
must be rated as SELV/PELV/Class 2/Limited Power.
▪Do not connect either the ‘Neutral or ‘Line’ signal of the 110/220VAC to device’s 0V pin.
▪Do not touch live wires.
▪All wiring activities should be performed while power is OFF.
▪Unused pins should not be connected. Ignoring this directive may damage the device
Caution
▪To avoid damaging the wire, do not exceed a maximum torque of 0.5 N·m
(5 kgf·cm)
▪Do not use tin, solder, or any substance on stripped wire that might cause the wire
strand to break
Use crimp terminals for wiring; use 26-14 AWG wire (0.13 mm 2–2.08 mm2).

User Guide

1. Strip the wire to a length of 7±0.5mm (0.250–0.300”).
2. Unscrew the terminal to its widest position before inserting a wire.
3. Insert the wire completely into the terminal to ensure a proper connection.
4. Tighten enough to keep the wire from pulling free.
Wiring Guidelines
▪Use separate wiring ducts for each of the following groups:
▪Group 1: Low voltage I/O and supply lines, communication lines.
▪Group 2: High voltage Lines, Low voltage noisy lines like motor driver outputs.
Separate these groups by at least 10cm (4"). If this is not possible, cross the ducts at a 90˚angle.
▪For proper system operation, all 0V points in the system should be connected to the
system 0V supply rail.
Earthing the Controller
To maximize system performance, avoid electromagnetic interference as follows:
▪Use a metal cabinet.
▪Connect the 0V terminal to the earth ground of the system at one point, preferably as near to the
controller as possible.
Power Supply
The controller requires an external 12 or 24VDC power supply. The permissible input voltage
range is 10.2-28.8VDC, with less than 10% ripple.
▪You must use an external circuit protection device
▪Install an external circuit breaker. Guard against short-
circuiting in external wiring
▪Double-check all wiring before turning on the power
supply
In the event of voltage fluctuations or non-conformity to
voltage power supply specifications, connect the device to a
regulated power supply

V230/280/290

Unitronics
Communication Ports
▪Turn off power before making communications connections
▪Signals are related to the controller’s 0V; this is the same 0V used by the power supply
Caution
▪Always use the appropriate port adapters
▪The serial ports are not isolated. If the controller is used with a non-isolated external
device, avoid potential voltage that exceeds ± 10V
Serial Communications
This series comprises 2 RJ-11-type serial ports and a CANbus port.
COM1 is RS232 only. COM2 may be set to either RS232 or RS485 via jumper as described below.
By default, the port is set to RS232.
Use RS232 to download programs from a PC, and to communicate with serial devices and
applications, such as SCADA.
Use RS485 to create a multi-drop network containing up to 32 devices.
Caution
▪COM1 & 2 are not isolated
Pinouts
To connect a PC to a port that is set to RS485, remove the RS485 connector, and connect the PC
to the PLC via the programming cable. Note that this is possible only if flow control signals are not
used (which is the standard case).

RS232 to RS485: Changing Jumper Settings
The port is set to RS232 by factory default.
To change the settings, first remove the Snap-in I/O Module, if one is installed, and then set the
jumpers according to the following table.
Note:
For V230/V280/V290 modules only there is a small window as described on page 6 for
jumper setting so there is no need to open the controller.
▪Before you begin, touch a grounded object to discharge any electrostatic charge
1. Before removing a Snap-in I/O Module or opening the controller, you must turn off the power

1. Locate the four buttons on the sides of the module, two on either side.
2. Press the buttons and hold them down to open the locking mechanism.
3. Gently rock the module from side to side, easing the module from the controller.
Re-installing a Snap-in I/O Module
1. Line the circular guidelines on the controller up with the guidelines on the Snap-in I/O Module as
shown below.
2 Apply even pressure on all 4 corners until you hear a distinct ‘click’. The module is now installed.
Check that all sides and corners are correctly aligned.

These controllers comprise a CANbus port. Use this
to create a decentralized control network using one
of the following CAN protocols:
▪CANopen: 127 controllers or external
devices
▪Unitronics’ proprietary UniCAN: 60
controllers, (512 data bytes per scan)
The CANbus port is galvanically isolated.
CANbus Wiring
Use twisted-pair cable. DeviceNet® thick shielded
twisted pair cable is recommended.
Network terminators: These are supplied with
the controller. Place terminators at each end of the
CANbus network.
Resistance must be set to 1%, 121Ω, 1/4W.
Connect ground signal to the earth at only one
point, near the power supply.
The network power supply need not be at the end of
the network.
