4.5.1 Verifying and adjusting the voltage selector
The voltage selector comes factory-adjusted to a setting of 230 V.
Prior to connecting the instrument to mains, verify whether the
voltage setting is correct for the mains electricity in your lab!
Incorrect voltage selector settings can lead to severe damage to
the instrument!
Prior to adjusting the voltage selector, disconnect the instrument
from mains!
Checking the voltage selector setting:
The voltage selector is located above the mains switch, on the rear left of
the control unit.
• Does the selected setting (1) correspond to the nominal voltage in your
laboratory?
• If yes: --> proceed to chapter 4.4.2 on the following page.
• If no: --> the voltage selector must be changed to the correct setting as
follows:
• Insert a small screw driver into the notch at the lower end of the voltage
selector housing and carefully remove the housing, using the screw-
driver as a lever.
• Remove housing (2) together with fuses (3) and the voltage selector
block (4) (white color).
• Remove the fuses.
• Remove the voltage selector block and re-insert it so that the correct
setting, corresponding to the mains voltage in your lab, is visible in win-
dow (1). (Selectable voltage settings: 100, 120, 230 and 240 V).
• Re-insert the fuses.
• Re-insert the housing together with the voltage selector block and the
fuses into the instrument and push slightly inwards until the voltage se-
lector housing locks in place (audible click).
• Verify once again, whether the setting that shows in window (1) is ap-
propriate for the mains voltage in your lab.
