The instruments are available in two versions: one for 220-230/240
V AC, referred to here as the 220 V model, and one for 100/120 V
AC, referred to here as the 120 V model.
As a safety precaution, check the code number and voltage printed
on the backpanels to ensure you have the correct model for your
local electricity supply.
Code number 18-1018-23:
Separation and control unit 120 V model
Development unit 120 V model
Code number 18-1018-24:
Separation and control unit 220 V model
Development unit 220 V model
Set the voltage selectors on the rear panels of the separation and
control unit and development unit according to your local electricity
supply. To do this:
• Check the voltage range of the mains electricity supply.
• Set the voltage selector to the appropriate setting according to
the table below.
Voltage range Voltage selector setting
For120 V model instruments:
90-110 100
108-132 120
For 220 V model instruments:
198-242 220-230
216-264 240
Important! Always disconnect the mains power cords when
servicing the system.
The operator is protected against high voltage by the separation
compartment lid when an electrophoresis is in progress.
If the lid is opened during a run, the high voltage supply switches off
automatically to eliminate electrical hazard. An alarm will sound
until the lid is closed or until the run is paused.
