1.2 DURING USE
1. Ensure the voltage and current set to zero, prevent a undesired output damage the circuit.
2. The supplied voltage should be within 110V AC or 220V AC
±
10% (60/50Hz) and the system is
capable for supplying the maximum power consumption as indicated on
section 3.1.
3. Keep a distance at least greater than 10cm between the power supply and other things for airy
reason when usage. Do not place this power supply in a hot, dusty, wet, corrosive gas stage or near
the poison substance.
