Bio-Rad Rotofor® and Mini Rotofor Cells - Manual (Page 8)

1.4 Safety
This instrument is intended for laboratory use only.
This product conforms to the “Class A” standard for electromagnetic emissions
intended for laboratory equipment applications. It is possible that emissions from
this product may interfere with some sensitive appliances when placed nearby or in
the same circuit as those applicances. The user should be aware of this potential
and take appropriate measures to avoid interference.
Power to the Rotofor preparative IEF cell is to be supplied by an external DC
voltage power supply. This power supply must employ a safety isolation transformer
to isolate the DC voltage output 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:
3000 VDC maximum voltage limit
15 Watts maximum power limit
50 °C maximum ambient temperature limit
Current to the cell, provided by the external power supply, enters the unit
through the lid assembly, providing a safety interlock. 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 any way.
Important: This Bio-Rad instrument is designed and certified to meet IEC1010-1*
safety standards. Certified products are safe to use when operated in accordance
with the instruction manual. This instrument should not be modified or altered in
any way. Alteration of this instrument will:
• Void the manufacturer’s warranty
• Void the IEC1010-1 safety certification
• Create a potential safety hazard
Bio-Rad is not responsible for any injury or damage caused by the use of this
instrument for purposes other than for which it is intended or by modifications of
the instrument not performed by Bio-Rad or any authorized agent.
*IEC1010-1 is an internationally accepted electrical safety standard for laboratory instruments.
