Before operating of the VCB, check that the spring is
charged. If the spring is not charged, it can be charged by

10 operations needed to fully charge the spring).

it is not necessary to charge the spring by hand. The motor
starts charging the spring automatically as soon as the auxili-
ary voltage is switched on.
