4.0 Setting the main voltage and replacing
the fuses
Warning
• The fuse box must not be removed from the power
control switch until the mains cable has been
disconnected.
• The two main fuses must be identical and correspond to
the chosen voltage.
c
Locate the main fuses in the fuse box in the power control
switch and check the voltage of the power control switch
(on/off switch (230V/115V)). If the voltage of the power
control switch differs from the line voltage, you must adjust
the voltage of the power control switch.
d
Open the lid of the fuse box using a screwdriver.
e
Remove the fuse box.
f
Remove both fuses and insert two new fuses. These must be
identical and should correspond to the line voltage.
• ITC-155: 115V, 2AT = 105014 / 230V, 1AT = 105007
