Figure A5.1 Module Replacement Procedure
Note the module replacement
Perform the following checks before replacing a module when there is an error:
- Check whether the load conforms to the specifications.
- Check whether the surge protector, if any, is functioning normally.
- Check for cabling errors such as wrong polarity orientation of a diode.
Note
The FA-M3 will fail again after replacing any module when there is a problem with the
external wiring, no surge protector is installed or a diode is connected in the reverse
polarity. Be sure to solve problems with the external equipment before replacing the
module.
