X1, X2, X3: plug-in jumpers to configure the inrush cur-
rent limitation
The inrush current limitation board must be configured in
line with the supply voltage. This is performed with the
help of plug-in jumpers on the inrush current limitation
board (1).
► Check the jumper arrangement and correct if neces-
sary.
Take note of the position of jumper J1 (see "6.1.1 In-
rush Current Limitation Board Transformer (A1)
