About the device
5.5.1 Terminal types
•
Models
from 400 V
output voltage
Screw-clamp terminal, plastic
Recommendation: ring cable lugs 6 mm
5.6 Grounding the output
Attention!
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 300 V nominal voltage!
Attention!
When grounding one of the DC output poles take care
if the consumer, for example an electronic load, is also
grounded on one of its poles! It may become a short-
circuit!

All screw connections are M4
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
, information „Remote sense
compensation“.
The connection for remote sense is done at the terminal „Sense“
on the rear side. Also see section 3.1.
Attention!
(+) Sense must only be connected to (+) at the load ap-
plication and (–) Sense must only be connected to (–)!
Else both systems can take damage.
For additional information also see section „8.7. Remote sense
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, in order to build parallel
connection 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 informa-
tion about the interface cards can be found in section „9. Digital
interfaces“, in the separate operating guide for the interface
cards and on the quick installation guide for the interface cards.
