You must connect the power supply circuit with a conductor cross-section of
at least 1.5 mm
2
(AWG 16) and protect it with a C10A or B10A type minia-
ture circuit breaker.
Supply via voltage transformers
DANGER
Electric shock!
If you supply the device via a voltage transformer, the output voltage of the
voltage transformer has no bearing on the protective conductor. As a result,
protection of the device against electric shock in the event of an error is not
guaranteed.
► Take appropriate measures to protect against electric shock according to
IEC 61140 and the local connection regulations.
Further conditions:
▪ For the correct dimensioning of the voltage transformer, observe the infor-
mation in the section "Technical data of the control unit" [
▪ During the charging process for the energy accumulator, the measuring
error of the voltage transformer can increase significantly (±2.3%). The
charging process for the energy accumulator takes approx. 35 s during
initial charging and approx. 0.3 s after each on-load tap-change operation.
▪ The transmission ratio of the voltage transformer must be taken into con-
sideration when setting the desired value.
The transmission ratio influences the voltage measurement value shown in
the display. Conversion within the controller is not possible.
