11.2 Replacing components
Replacing fuses for 1500 A to 3000 A units
The fuses are accessible after removing the front cover and withdrawing the fan module (see
the previous chapter). Each fuse is fixed with 2 hex screws. Tightening torque 25 Nm.
When installing the fuses, observe the following:
● Install the fuses with the same alignment as the fuses to be replaced. The rupture
indicator of the fuses in the left-hand and right-hand series must point towards the center
of the unit.
● The fixing screws have different lengths. Re-use the screws at the same position.
