About the device
5.5.1 Terminal types
• Models from 400V output voltage
Screw-clamp terminal, plastic
Recommendation: ring cable lugs 6mm
5.6 Grounding the output
Attention! Read carefully!
Grounding of the DC minus (-) output of single units or
multiple units in parallel is always possible. Grounding
the DC plus (+) output is only allowed for models of up to
300V nominal voltage!
Attention! When grounding one of the DC output pole take
care if the consumer, for example an electronic load, is also
grounded on one of its poles! It may become a short-circuit!

5.7 Terminal „Sense“ (Remote sense)
In order to compensate the voltage drop along the load cables,
the power supply can „sense“ the voltage at the load instead at
the output. It will regulate the output voltage so that the desired
voltage is provided to the load. For maximum regulation see
section „2.2. Device specications“, information „Remote sense
compensation“.
The connection for remote sense is done at the terminal „Sense“
on the rear side. Also see section 3.1.
(+) Sense must only be connected to (+) at the load appli-
cation and (–) Sense must only be connected to (–)! Else
both systems can take damage.
For additional information also see section „8.7. Remote sense
is active“.
5.8 Terminal „Share“
In case Share bus operation is wanted, the „Share“ terminal of
the concerning units just have to be connected to each other:
Nothing more required. For details about Share bus operation
refer to section „13.1. Parallel connection in Share bus mode“.
Attention! Share bus connection with units different to
3U series, which also feature a Share bus, is not allowed!
5.9 Interface card slot
The unit can be equipped with an optional interface card. The
slot to insert the card is located at the rear side. Further infor-
mation about the interface cards can be found in section „9.
Pluggable interface cards“, in the separate instruction manual
for the interface cards and on the quick installation guide for
the interface cards.
