When the electrical leads are properly connected, the power selector
switch can be set to the appropriate voltage: 100V or 200V. The
LED on the front of the power supply will light up to indicate that
current is flowing.
When an electrophoresis run starts, visually inspect the electrodes in
the gel tank. Small bubbles coming from the electrodes will indicate
that current is flowing.
4. Maintenance and Cleaning
The Mini Power Supply does not require any routine or special
maintenance.
Always disconnect the power cord and electrical leads for cleaning.
When cleaning the surfaces of the instrument, use a cloth damp with
water.
There are no user-serviceable parts inside. Do not open the casing
of the Mini Power Supply.

The resistance of the load is
too low. Excess current is
causing the maximum
power (wattage) to be
exceeded.
Adjust the concentration of
buffer to maintain proper
level of resistance.
