2.3.6 Connection of remote sensing
•
Remote sensing is only effective during constant voltage operation (CV) and for other regulation modes
the sense input should be disconnected, if possible, because connecting it generally increases the os-
cillation tendency
•
The cross section of the sense cables is noncritical. Recommendation for cables up to 5 m (16.4 ft):
use at least 0.5 mm²
•
Sense cables shouldn’t be twisted, but laid close to the DC cables, i. e. Sense- cable close to DC- cable
to the source etc. to damp or avoid possible oscillation. If necessary, an additional capacitor should be
installed at the load/source to eliminate oscillation
•
The Sense+ cable must be connected to DC+ on the source and Sense- to DC- at the source, otherwise
the sense input of the device can be damaged. For an example see Figure 13 below.
•
In master-slave operation, the remote sensing should be connected to the master unit only
•
The dielectric strength of the sense wires must always at least match the DC voltage rating!
Dangerous voltage on the sense terminals! The sense cover must always be installed.

Allowed connection schemes:
2.3.7 Grounding of the DC terminal
Besides the main purpose of grounding the enclosure, the extra grounding point (item “10” in
1.8.4.3
) can be used to ground any the DC terminal poles. Doing so causes a potential shift
on the opposite pole against PE. Because of insulation, there is a maximum allowed potential
shift dened for the negative DC terminal pole, which depends on the device model. Refer to
“1.8.3. Specic technical data”
for the levels.
In case any DC pole is grounded, the operator of the device must reinstate the basic protection for
human safety by installing appropriate external means, for instance a cover, everywhere the potential
of the DC terminal is connected to.
