Avoiding Electrical Shock
Follow the guidelines below to ensure safe operation of the unit.
The powerPRO Power Supply has been designed to utilize shielded wires thus
minimizing any potential shock hazard to the user. Cleaver Scientific
recommends against the use of unshielded wires.
To avoid electrical shock:
1. In the event of solution spilling on the instrument, it must be dried out for
at least 2 hours and restored to NORMAL CONDITION before each
operation.
2. Never connect or disconnect wires loading from the power jacks when
the red indicator light of power switch is on.
3. WAIT at least 5 seconds after stopping a run before handling output leads
or any connected apparatus.
