1.3 Safety
Power to the Vertical units is to be supplied by an external DC voltage power supply that must be
ground isolated so that the DC voltage output floats with respect to ground. For any power
supply used, the maximum specified operating parameters for the units are:
Maximum Limits
50VDC/cm of gel
60 watts power
80mA current
55°C ambient temperature
Current to the unit, provided from the external power supply, must enter the unit through the lid
assembly, providing a safety interlock to the user. Current to the unit is broken when the lid is
removed. Do not attempt to use the unit without the safety lid, and always turn the power
supply off before removing the lid, or when working with the unit in any way. Follow
safety precautions specified by the power supply manufacturer.
