Wiring connection
CAUTION
#1 REFER to TABLE 1 on page 6 for input control voltages.
These recommended wiring diagrams are specifically where the control supply voltage (U
S
) is identical
to the control circuit voltage (U
C
) and not to be supplied separately. Other wiring configurations must
also be in accordance with existing local and national codes and regulations.
#2 Power factor correction capacitors must NOT be positioned between the soft start and the motor or
there is a risk of damaging thyristors due to current peaks.
