Bio-Rad Sub-Cell® Model 192 Cell - Manual (Page 5)

Before every use, inspect the base for cracks or chips. Cracks or chips may cause the
buffer to leak from the base and cause a potential electrical hazard. Additionally, inspect all
electrical cables, banana jacks, recirculation port fittings, tubing, and plugs for loose
connections, cracks, breaks or corrosion. Do not use any part that is cracked, charred or
corroded. These parts may also cause a potential electrical shock. Contact your local Bio-Rad
representative before using a part that may be considered hazardous.
During electrophoresis inspect the base and workbench for any signs of buffer leakage.
If leaking buffer is detected disconnect the power to the cell immediately and contact your
Bio-Rad representative.
Power to Sub-Cell units 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 Bio-Rad power supplies meet this important safety requirement. The
recommended power supply for this apparatus is the PowerPac 300. The PowerPac 300
contains several safety features such as no load, overload, rapid resistance change, and ground
leak detection capabilities. The maximum specified operating parameters* for the
Sub-Cell Model 96 and Model 192 systems are:
200 VDC Maximum voltage limit
70 Watts Maximum power limit
50 °C Maximum buffer temperature
4 °C – 40 °C Ambient temperature limits
* IEC 1010-1 certification applies to equipment designed to be safe at the operating parameters listed above. Additionally, both
Sub-Cell Model 96 and Model 192 have a maximum operating relative humidity of 80% for temperatures up to 31 °C decreasing
linearly to 50% relative humidity at 40 °C. Certification is valid when systems are operated at altitudes up to 2000 meters.
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 any way.
Important: These Bio-Rad instruments are designed and certified to meet IEC 1010-1*
safety standards. IEC-certified products are safe to use when operated in accordance with
this instruction manual. This instrument should not be modified in any way. Alteration of
this instrument will:
• Void the manufacturer’s warranty
• Void the IEC 1010-1 safety certification
• Create a potential safety hazard
Bio-Rad is not responsible for any injury or damage caused either by the use of this instru-
ment for purposes other than for which it is intended or by modifications of the instrument not
performed by Bio-Rad or any authorized agent. No user-serviceable parts are contained in
this apparatus. To ensure electrical safety, do not attempt to service this apparatus.
* IEC 1010-1 is an internationally accepted electrical safety standard for laboratory instruments.
