Input/Ouput Bridges test
The instrument suitable for that operation is a digital multimeter set to “diodes test”
Check the diodes and the IGBTs after having disconnected the power terminals to avoid false measurements due to external devices.
The first step is to do a visual test then follow the sequence shown below:

Optical fibers cable test
If there is a malfunctioning of the data transmission by optical cable, two situations are possible:
•
Optical cable broken
•
Malfunctioning of the data transmitter/receiver
To verify the optical cable it is necessary to do the following test:
Remove the optical cable connection and light one end by a flashlight or similar device; if the light is visible on the other end, the optical
cable is not interrupted.
NOTE the above-mentioned test may be not enough; in this case a dedicated device is necessary.
