Replacing fuses
− Open the low voltage compartment door.
− Release the twist lock fastener (figure 4.3.5.3). The fuse
flap then automatically swings out (figure 4.3.5.4).
− Draw the lid with the fuse to be replaced out of the box
(figure 4.3.5.5). Turning and gently shaking the lid makes it
easier to withdraw it.
− Remove the lid with the fitted fuse.
− Loosen the clamping band and remove the fuse from the
lid.
