2) The following diagram shows the circuit configuration.
Do not replace the built-in fuse of the 12/24-VDC 32-point Output Modules.
If the built-in fuses are replaced by anyone other than a Yaskawa-approved
technician, failure or malfunction may occur in the Modules.
If using a 12/24-VDC 32-point Output Module, connect a fuse, which complies with
the load specifications, in series with the load.
A protective fuse built into the following 12/24-VDC 32-point Output Modules
does not protect the output element. If a fuse is not connected, a fire or dam-
age to the devices or output circuits may occur if the load is short-circuited or
the circuit overloaded.
