Fuse protection of the power module electronics supply of the I/O level
Fuse-protect the electronics supply externally!
Use:
A 1 A fuse (fast)
or
a 1 A circuit breaker of characteristic Z
or
MICO load circuit monitoring,
e.g. MICO 4.4, Art.-No. 9000-41034-0100400
External fuse
To protect the power supply, Murrelektronik provides a number of circuit break-
ers. They can be found under the product name
MICO

NOTICE
Voltage supply interruptions!
The module does not have any internal buffer to bridge voltage supply inter-
ruption according to the standard EN 61131-2.
For power supply use a power supply unit which is capable of bridging volt-
age supply interruptions of at least 10 ms!
NOTICE
Exceeding of the maximum current load!
The contacts can be loaded with maximum 10 A.
Observe the maximum current load!
