11. The unit shall be operated only by qualified personnel.
Safety Information
Use high level of precaution against any electrical device. Before connecting
the electrical supply, check to see if the supply voltage is within the range
stated at the rating label, and see to it that the device be seated firmly. Place
the unit in a safe and dry location; it must NOT touch the surrounding. Follow
the safety precautions for chemicals / dangerous materials. If needed, please

Environmental Conditions
Ensure the instrument is installed and operated strictly under the following
conditions:
1. Indoor use only
2. ≤95% RH
3. 75 kPa – 106 kPa
4. Altitude must not exceed 2000 meters
5. 4℃~ 40℃ operating temperature
6. Pollution degree: 2
7. Mains supply voltage fluctuations up to ±10% of the normal voltage
Avoiding Electrical Shock
Follow the guidelines below to ensure safe operation of the unit.
The Mini Pro 300V Power Supply has been designed to utilize 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 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.
4. ALWAYS make sure that your 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 grounded AC outlet.
