Screw-clamp terminal, plastic
Recommendation: ring cable lugs 6mm
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 300V nominal voltage!
Attention!
When grounding one of the output poles always check if
one of the poles of the load (eg. electronic load) is also
grounded. This could result in a short-circuit!
Attention!
Watch the potential shift of the output poles when using
series connection! Grounding is hereby only recommen-
ded at the pole with the lowest potential against ground.
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.
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 „7.7. Remote sense
operation“.
About the device
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 „11.1. Parallel connection in Share bus mode“.
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.
Digital interface cards“, in the separate instruction manual for
the interface cards and on the quick installation guide for the
interface cards.
