Safety instructions
Overview
General safety instructions
This chapter states the general safety instructions that must be followed when installing and operating the
RAIO-01 Analogue I/O Extension module.
The material in this chapter must be studied before attempting any work on, or with, the unit.
In addition to the safety instructions given below, read the complete safety instructions of the specific drive you are working on.
WARNING!
All electrical installation and maintenance work on the drive should be carried out by qualified electricians only.
The drive and adjoining equipment must be properly earthed.
Do not attempt any work on a powered drive. After switching off the mains, always allow the intermediate circuit capacitors 5 minutes to discharge before working on the frequency converter, the motor or the motor cable. It is good practice to check (with a voltage indicating instrument) that the drive is in fact discharged before beginning work.
The motor cable terminals of the drive are at a dangerously high voltage when mains power is applied, regardless of motor operation.
There can be dangerous voltages inside the drive from external control circuits even when the drive mains power is shut off. Exercise appropriate care when working on the unit. Neglecting these instructions can cause physical injury or death.

Chapter 3 – Installation
WARNING!
Follow the safety instructions given in this guide and in the Hardware Manual of the drive.
Mounting
The RAIO-01 is to be inserted into an optional module slot on either the RMIO board of the drive, or on an
AIMA-01 I/O Module Adapter. The module is held in place with plastic retaining clips and two screws .
The screws also provide the earthing of the I/O cable shield connected to the module, and interconnect the GND signals of the module and the RMIO board/AIMA adapter.
On installation of the module, the signal and power connection to the drive is automatically made through a
38-pin connector.
Mounting onto
RMIO board
1. Insert the module carefully into SLOT 1 or SLOT 2 on the RMIO board of the drive until the retaining clips lock the module into position.
2. Fasten the two screws (included) to the stand-offs.
Note: Correct installation of the screws is essential for fulfilling the EMC requirements and for proper operation of the module.
3. Remove the cover of the module enclosure (see page
).
4. Set the configuration DIP switches of the module to
the required position (pages 16 and
) and refit the cover.

Removing and refitting the cover of the enclosure
To choose operating mode and input signal type, the cover of the module enclosure must be removed. This can be done by carefully bending the two cover retaining clips with a small screwdriver (see
) and lifting the cover off.
Refit the cover by pushing it back into its place until the retaining clips lock it into position.

Chapter 3 – Installation
Input mode selection
The operating mode of the analogue inputs can be selected using the configuration DIP switch (S2) on the circuit board of the module. The drive parameters must be set accordingly.
In bipolar mode, the analogue inputs can handle positive and negative signals. The resolution of the A/D conversion is 11 data bits (+ 1 sign bit). The way the drive interprets the negative range of the inputs depends on the settings of the drive. See the Firmware
Manual of the drive .
In unipolar mode (default), the analogue inputs can handle positive signals only. The resolution of the A/D conversion is 12 data bits.

Note: If the transducers or indicators are located far away from each other, earth the shield at one unit through a capacitor (e.g. 10 nF/400 V) to avoid circulating earth current flow.
Note: X1 and X2 have separate RC circuits as shown above, i.e. the SHLD terminals on one terminal block are connected together and earthed through a common
RC circuit.

Chapter 3 – Installation
Node ID selection
If the RAIO-01 module is mounted onto an external
AIMA-01 I/O Module Adapter, choose the proper node
ID for the module using the node ID selector (S1, range
1…15). Setting the node ID is not required when the module is mounted into SLOT 1 or SLOT 2 on the drive.
The default setting of selector S1 is 5.
Programming
The communication between the module and the drive is activated by a drive parameter. (Ensure that the parameter settings correspond to the mode switch setting of the module.) The RAIO-01 can replace and/or extend certain standard inputs and outputs. See the drive Firmware Manual , Parameter Group 98.
Note: The new settings take effect only when the module is powered up.

Adapter installation
There is one status LED (WD/INIT, yellow) on the
RAIO-01 module. The LED is lit when the drive is configuring the module at power-up.
In case the LED does not go out after one second:
• The configuration has failed.
- Cycle the power supply of the drive.
• The module has a hardware failure.
- Ensure the 38-pin connector is properly inserted.
- Contact an ABB service representative.
• There is no communication with the drive.
- Check that the drive is powered.
- Check the module node ID.
- Check that the fibre optic cables are connected correctly (transmitters to receivers) and the connectors properly inserted.
- Check the fibre optic cables visually for dirt or flaws.
- Ensure the 38-pin connector is properly inserted.
- Try new fibre optic cables.
- Contact an ABB service representative.
