Connection cables
On selecting a sense cable you must take into account the following:
Cable cross-section: 0.5 mm
2
, per cable
Single cables are mostly adequate.
Cable resistance: can be ignored
Only a low current flows through the sense cable.
(OP-Amp input)
Voltage class
The sense cable must correspond to the voltage class of the de-
vice. (Particularly from 800 V output voltage).
EMI shielding/coupling of interference
Use shielded cables to prevent the coupling of electrical interfer-
ence onto the sense input.
Increase the interference immunity by means of simple measures:
Simply twist the sense cables.
Lay the sense cables physically separate from
power cables.
Software requirements
The following conditions must be met for the sense function to be sup-
ported and so that it can be activated.
Main DSP firmware:
from V4.11.33
TopControl application:
from V4.01.12
User rights for TopControl application:
“
Advanced User
” (see chapter 6.4.4, page 175)
Connection must be established between TopCon power supply
and TopControl application, see chapter 6.4.3.1, page 173.
State: “ VOLTAGE_OFF”
The sense function can only be activated if there is no voltage
present on activation.
