3.3 Wiring the iC9200
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!
(g) Fusing
• The power section supply is to be externally protected with a fuse, which corresponds to the maximum current.
This means max. 10A is to be protected with a 10A fuse (fast) respectively by a line circuit breaker 10A char-
acteristics Z!
• 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 characteristics Z.
(h) State of the Electronic Power Supply via LEDs
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.
CAUTION
Since the power section supply is not internally protected, it is to be externally protected
with a fuse, which corresponds to the maximum current. This means max. 10A is to be pro-
tected by a 10A fuse (fast) respectively by a line circuit breaker 10A characteristics Z!
