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. 10 A is to be protected by a 10 A
fuse (fast) respectively by a line circuit breaker 10 A 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!
Protection
•
The power section supply is to be externally protected with a fuse, which corresponds to
the maximum current. This means max. 10 A is to be protected with a 10 A fuse (fast) re-
spectively by a line circuit breaker 10 A characteristics Z!
•
t is recommended to externally protect the electronic power supply for bus coupler and I/O
area with a 2 A fuse (fast) respectively by a line circuit breaker 2 A characteristics Z.
•
The electronic power supply for the I/O area of the power module PW 24 V / 5 V (order no.
83.036.0040.0) should also be externally protected with a 1 A fuse (fast) respectively by a
line circuit breaker 1 A characteristics Z.
State of the electronic power supply via LEDs
After PowerON of the
ricos
FLEX system the LEDs RUN respectively MF get on so far as the sum cur-
rent does not exceed 3 A. With a sum current greater than 3 A the LEDs may not be activated. Here
the power module with the order number 83.036.0040.0 is to be placed between the extension mod-
ules.
Deployment of the power modules
•
If the 10 A for the power section supply is no longer sufficient, you may use the power mod-
ule PW DC 24 V with the order number 83.036.0030.0. So you have also the possibility to de-
fine isolated groups.
•
The power module PW 24 V/5 V with the order number 83.036.0040.0 is to be used if the 3 A
for the electronic power supply at the backplane bus is no longer sufficient. Additionally
you get an isolated group for the DC 24 V power section supply with max. 4 A.
•
By placing the power module PW 24 V/5 V at the following backplane bus modules may be
placed with a sum current of max. 2 A. Afterwards a power module is to be placed again. To
secure the power supply, the power modules may be mixed used.

To secure the power supply, the power modules may be mixed used.
