Device connection terminal blocks
The front-mounted DC input and DC output terminal blocks
and the signal terminal blocks of the power supply feature
Push-in connection technology. The wiring is performed by
plugging in, without tools.
For the necessary connection parameters for the
connection terminal blocks, refer to the technical
data section.
9.1
Input
The power supply is connected on the primary side via the
Input +/- connection terminal blocks.
9.2
Protection of the primary side
Installation of the device must correspond to EN 61010
regulations. It must be possible to switch off the device using
a suitable disconnecting device outside the power supply.
The line protection on the primary side is suitable for this
(see technical data section).

DC applications require upstream installation of a fuse that
is permitted for the operating voltage.

9.3
Output
By default, the power supply is pre-set to a nominal output
voltage of 24 V DC.
The output voltage is adjusted via the two arrow keys (-)
and (+) on the front of the power supply.
When you press the arrow key once briefly, the output
voltage is reduced (-) or increased (+) by 3 mV. When you
press the arrow key for longer, the voltage is adjusted in
100 mV increments.
9.4
Protection of the secondary side
The power supply is electronically short-circuit-proof and
no-load-proof. In the event of an error, the output voltage is
limited
If sufficiently long connecting cables are used,
fuse protection does not have to be provided for
each individual load.
If each load is protected separately with its own
protective device, the selective shutdown in the
event of a fault enables the system to remain
operational.
