Fusing
Internal fusing of the field supply is possible for various field voltages via an
appropriate power supply module.

Observe the maximum power dissipation and, if required, UL requirements!
In the case of power supply modules with fuse holders, you must only use fuses
with a maximum dissipation of 1.6 W (IEC 127).
For UL approved systems only use UL approved fuses.
In order to insert or change a fuse, or to switch off the voltage in succeeding I/O
modules, the fuse holder may be pulled out. In order to do this, use a screwdriver
for example, to reach into one of the slits (one on both sides) and pull out the
holder.
