E. Electrical Connections to the Safety Lid
The Hoefer HE-PLUS Gel System can only
be operated with the safety lid in place. Elec-
trical current is supplied through the tank
electrodes from the power supply. A micro
switch connector in the power supply ensures a
complete current path, yet allows the lid to be
removed from the unit without disturbing the
loaded samples.
1
Make sure the power supply is turned off.
2
Plug the male ends of the black (–) and red (+)
electrodes into the jacks on the side of the
power supply.
3
After the samples have been loaded into the gel, place
the lid over the unit so that the lid covers align with
the tank.
Set the lid straight down so that the lid rests squarely
on the tank.
4
Plug the power supply into a wall outlet.
