C.B.S.  Scientific 6 Adjustable Height Sequencer
1.3 Safety
Power to the Sequencing unit 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.
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.
