1.2 Safety
Power to the PROTEAN Plus Dodeca cell is supplied by an external DC voltage power
supply (not included). The output of the 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 PROTEAN Plus Dodeca cell are as follows:
1000 VDC voltage limit
250 watts power limit
40 °C ambient temperature limit
The current to the cell enters the unit through the lid assembly that provides a safety interlock
to the user. Always turn off the power supply before removing the lid. Do not attempt to use the
cell without the safety lid.
