3.5 Electrical connections
3.5.1 Adjusting the voltage selector
The voltage selector is preset to match
the nominal voltage of the country of
delivery.
Nevertheless, it is absolutely neces-
sary that you check the setting of the
voltage selector prior to connecting
the instrument to mains, to make sure
the setting is correct!
Connecting the instrument to mains
with the voltage selector at a wrong
setting can cause severe damage to
the instrument!
• Check the setting showing in window (1).
• Does it correspond to the nominal voltage in
your laboratory?
• If the setting is correct: --> Go to next page
(chapter 3.5.2).
• If the setting is not correct, the voltage se-
lector must be changed to the correct
setting: --> Continue to follow instructions
on this page.
• Insert the small
screwdriver (3 x 50 mm)
into the notch at the
lower end of the voltage
selector shell. Carefully
release the lock, using
the screwdriver as a le-
ver.
• Remove shell (2) with fuses (3).
• Take the fuses out of the shell.
• Pull the voltage selector out of the shell and
reinsert it such that the desired setting is
visible in the small window (1) of the shell.
• Reinsert the shell together with voltage se-
lector and fuses into the corresponding
opening at the back of the instrument and
apply light pressure until it locks.
• Double-check if the correct setting now
shows in window (1).
