Load
The load resistor for the open-delta connection should be located externally, but must not be
grounded externally. Terminal XB-2 is used for grounding. R701 should be removed.
6.6.3.2 External current transformers in V-circuit with +10 V at rated armature DC current
Connection
The output signal of the V-circuit is connected to terminals XB-1 (+) and XB-2 (-), terminals
XB-3 and XB-4 must be shorted.
S700 switch positions:
Remove R701. The difference amplifier at the power interface is active. The input signal is
reduced to a tenth of its value (10 V to 1 V at rated DC current).
