CAUTION!
Since the power section supply is not internally protected, it is to be exter-
nally protected with a fuse, which corresponds to the maximum current.
This means max. 10A is to be protected by a 10A fuse (fast) respectively
by a line circuit breaker 10A characteristics Z!
The electronic power section supply is internally protected against higher
voltage by fuse. The fuse is within the power module. If the fuse releases,
its electronic module must be exchanged!

The power section supply is to be externally protected with a fuse, which corresponds

It is recommended to externally protect the electronic power section supply for CPU
an I/O area with a 2A fuse (fast) respectively by a line circuit breaker 2A characteris-
tics Z.
After PowerON the RUN respectively MF LED at every System SLIO module is on, so far
as the sum current does not exceed the maximum value. With the CPU this is 3A. If the
total current exceeds the maximum value, the LEDs are no longer triggered. Here the
power module with the order number 007-1AB10 is to be placed between the periphery
modules.
1.
Power-off your system.
2.
Remove the connector of the power supply of the CPU. By pressing the release
button as shown, the connector is released and can be removed.
3.
Turn all the locking lever of the CPU upwards.
4.
Pull the CPU forward.
