Bio-Rad Criterion™ Cell - Manual (Page 4)

1.3 Safety
Power to the Criterion cell is supplied by an external DC voltage power supply (not included).
The output of this power supply must be isolated from external ground to insure that the DC
voltage output floats with respect to ground. All Bio-Rad power supplies meet this
important safety requirement. Regardless of the power supply used, the maximum specified
operating parameters for the Criterion Cell are as follows:
600 VDC maximum voltage limit
15 watts maximum power limit
50 °C maximum ambient temperature limit
The current to the cell enters the unit through the lid assembly that provides a safety
interlock to the user. The current to the cell and the lid's upper electrodes is broken when the
lid is removed. Always turn off the power supply before removing the lid. Do not attempt to use
the cell without the safety lid.
Important: This Bio-Rad product is designed and certified to meet *EN61010-1 safety
standards. Certified products are safe to use when operated in accordance with the instruction

instrument will
• Void the warranty
• Void the EN61010-1 certification, and
