Bio-Rad Model 111 Mini IEF Cell - Manual (Page 6)

1.3 Safety
Power to the Model 111 Mini IEF Cell is to be supplied by an external DC voltage power
supply. This power supply must be ground isolated in such a way that the DC voltage output floats
with respect to ground. All of Bio-Rad's power supplies meet this important safety requirement.
Regardless of which power supply is used, the maximum specified operating parameters for the
cell are:
500VDC maximum voltage limit
5 Watts maximum power limit
50° C maximum ambient temperature limit
Current to the cell, provided from the external power supply, enters the unit through the lid
assembly, providing a safety interlock to the user. Current to the cell is broken when the lid is
removed. Do not attempt to circumvent this safety interlock, and always turn the power supply off
before removing the lid, or when working with the cell in anyway.
