Notes
- The power supply is not provided with fuses,
but all of its outputs are protected against
overloading and short circuiting by tempera-
ture sensors. To reset the power supply, pow-
er must be cut off for about one minute and
can be restored after having eliminated the
defect.
- The power supply must be installed in a dry
place and can be fixed on DIN bar or on a wall
by using the expansion plugs.
