Avoiding Electrical Shock
Follow the guidelines below to ensure safe operation of the unit.
MS 250V / MS 300V power supply series has been designed to use with
shielded wires thus minimizing any potential shock hazard to the user. Major
Science recommends against the use of unshielded wires.
To avoid electrical shock:
1. In the event of solution accidentally spilled into the instrument, it must be
dried out for a period of time, at least 2 hours, and restored to NORMAL
CONDITION before each operation.
2. NEVER connect or disconnect wire leads from the power jacks when the red
indicator light at the Start/Stop key is light.
3. WAIT at least 5 seconds after stopping a run before handling output leads or
connected apparatus.
4. ALWAYS make sure that hands, work area, and instruments are clean and
dry before making any connections or operating the power supply.
5. ONLY connect the power cord to a properly 3-prong grounded AC outlet,
