When overcurrent protection devices need to be installed to the DC power supply, some
power supplies that need to conform to the safety standards (UL60950-1, etc.) require
installation of the specified overcurrent protection device based on their specifications. In
such cases, make sure to install the specified overcurrent protection device as described in
the figure below. When overcurrent protection devices are not required in the DC power
supply specifications, they do not need to be installed.

When overcurrent protection devices are required
In the event that a failure occurs, such as overload or abnormal temperature, IB-P02F-P-FT
will transmit the data of failure generation to external devices via the PROFINET
communications, as well as stopping the drive operation. However, it does not have the
MDR power shutdown function. Accordingly, if the MDR power needs to be shut down in the
event of a failure, as described in SW1 of the figure below, add the power shutdown circuit
using a PC, and shut down the power from these devices in the event of a failure.
When the communication function on the controller is not used, a failure cannot be detected
from the communication data. For this reason, to shut down the MDR power, independent
overload detection devices that have the power shutdown function need to be added outside
this product.
