2) The following diagram shows the circuit configuration.
Do not replace the built-in fuses of the Register I/O Modules.
If the built-in fuses are replaced by anyone other than a Yaskawa-approved
technician, a failure or malfunction may occur in the Register I/O Modules, and
the guarantee is void.
Status Indication R: Lights while the Module is operating normally.
ACTIVE: Lights during input output processing.
F: Lights when the fuse is blown out or the output power supply
is disconnected.
