All electronic equipment sensitive to damage from electrostatic discharge,
which can cause the control unit to malfunction or fail.
• To protect electronic components from static damage, take the•
precautions listed below.
1. ▷
Avoid build-up of static electricity on your body by not wearing clothing made of
synthetic materials. Wear cotton or cotton-blend materials as much as possible because
these do not store static electric charges as easily as synthetics.
2. ▷
Before working on terminals on the control unit, ground yourself by touching
and holding a grounded metal object (pipes, cabinets, equipment, etc.) to
discharge any static electricity.
Alternatively wear an ESD wrist band connected to ground.
3. ▷
Before any maintenance work on the control unit, ground yourself by
touching and holding a grounded metal object (pipes, cabinets, equipment,
etc.) to discharge any static electricity.
Alternatively wear an ESD wrist band connected to ground.
4. ▷
Keep plastic, vinyl, and Styrofoam materials (such as plastic or Styrofoam cups,
cigarette packages, cellophane wrappers, vinyl books or folders, plastic bottles, etc.)
away from the control unit, modules and work area.
5. ▷
Opening the control cover may void the unit warranty. Do not remove the printed circuit
board (PCB) from the control cabinet unless instructed by this manual.
If instructed by this manual to remove the PCB from the control cabinet,
follow these precautions:
• Ensure that the device is completely voltage-free (all connectors have•
to be disconnected).
• Do not touch any part of the PCB except the edges.•
• Do not touch the electrical conductors, connectors, or components with•
conductive devices or with bare hands.
• When replacing a PCB, keep the new PCB in the plastic antistatic•
protective bag it comes in until you are ready to install it. Immediately
after removing the old PCB from the control cabinet, place it in the
antistatic protective bag.
For additional information on how to prevent damage to electronic components caused
by improper handling, read and observe the precautions in:

3.2.1 Wiring Diagram
General recommendations
Ensure appropriate cable cross sections following the local standards and restrictions.
The maximum cable cross section of the terminal blocks is 2.5 mm2.
For every type of signal lines like power supply, DO:
• Return line has to be close to forward signal line.•
• Use cables instead of single wires.•
◦In case of using single wires please do at least one twist per meter to keep ◦
wires together closely.

Maximum CAN bus length
The maximum length of the communication bus wiring is dependent on the con󰍓gured
baud rate. Observe the maximum bus length.
We recommend to use shielded cables.

3.2.2 CAN Bus Interfaces

When the cable is too long, impedance 120 Ohm matching is required at the CAN
transceiver to meet the communication quality, and the shielding layer of the shielded
wire needs to be grounded.
Troubleshooting
If there is no data transmission on the CAN bus, check for the following common CAN bus
communication problems:
• A T-structure bus is utilized•
• CAN-L and CAN-H are switched•
• Not all devices on the bus are using identical baud rates•
• Termination resistor(s) are not activated•
• The con󰍓gured baud rate is too high for wiring length•
• The CAN bus cable is routed in close proximity with power cables•
Woodward recommends the use of shielded, twisted-pair cables for the CAN bus (see
examples).

• UNITRONIC-Bus LD 2×2×0.22•
