4.2.2 Changing the fuses on the microscope
The fuses for the instrument input voltage are
positioned on the rear of the microscope stand.
The fuse compartment, which contains two T4.0
A/H 250 V 5x20 mm fuses, is combined with the
instrument socket.
If fuses blow, the cause must be found out first
and any technical defect must be efficiently
eliminated.
Always pull the power plug before
changing the fuses.
• Disconnect the instrument from the line. Pull
out fuse compartment (4-1/1) in forward
direction.
• Remove fuses from the holder and insert new fuses.
• Insert fuse holder back in the fuse compartment (4-1/2) until stop. Plug in power cords.
