electrically isolated from ground to reduce the risk of electrical shock to the user. Follow the
guidelines below to ensure safe operation of the unit.

300W Power Supply has been designed for use with electrophoresis cells with
shielded banana plugs thus minimizing any potential shock hazard to the user. Life Technologies
recommends against the use of unshielded banana plugs.
To avoid electrical shock:
1.
NEVER connect or disconnect wire leads from the power jacks when the red indicator light at
the Start/Stop key is on or when “RUNNING” is displayed on the screen.
2.
WAIT at least 5 seconds after stopping a run before handling output leads or connected
apparatus.
3.
ALWAYS make sure that hands, work area, and instruments are
clean
and
dry
before making
any connections or operating the power supply.
4.
ALWAYS connect the power supply to a properly grounded AC outlet.
