Publication 1768-IN001B-EN-P - July 2006
• The 1768 power supply has a different distance rating than the 1769 power
supply. For more information, see Place 1769 I/O Modules in a 1768
CompactLogix System.
Use a Fuse with the Power Supply
The CompactLogix power supply has an internal, non-replaceable fuse soldered in
place. This fuse is intended to guard against fire hazard due to short circuit
conditions. We recommend you put a user-replaceable fuse in line between
incoming power and the power supply terminal block.
User Power Overcurrent Condition
In the event of an overcurrent condition, the power supply outputs latch off and
remain off until the overcurrent is removed and the power is cycled. Reload the
your program following a power supply shutdown.
ATTENTION
To avoid unexpected operation due to 24V dc user-power shutdown, monitor
the 24V dc user output with a 24V dc input channel.
