4. Advanced preparation
When overcurrent protection devices need to be installed to the 24V DC power
supply unit, 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 over-
current protection device as described in the figure below. When overcurrent protec-
tion devices are not required in specifications of the 24V DC power supply unit, they
do not need to be installed.
■
At the time of power shutdown, not only the MABS main unit power, but also the
IB-E06F-M1 control power will be shut down.

-1 When overcurrent
protection devices
are required
In the event that a failure occurs, such as overload or abnormal temperature,
IB-E06F-M1 will transmit the data of failure generation to PLC devices, as well as
stopping product operation. However, the product does not have the power shut-
down function. Accordingly, if the product’s 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 PLC.

-3 Adding the power
shutdown circuit of
this product in the
event of a failure
In case of using power supply device except a limit power supply, install the over-
current protection device on the 24V DC line.
