4. OPERATION INSTRUCTIONS 4-1 Precaution (1) AC input AC input should be within the range of line voltage ±10% 50/60Hz. WARNING. To avoid electrical shock, the power cord protective grounding conductor must be connected to ground. (2) Installation Avoid using the power supply in a place where the ambient temperature exceeds 40ºC. The heat sink located at the rear of the power supply must have sufficient air space for radiation. - Page 11 indicator goes off and the CC indicator comes on. Fig. 4-1 Constant Voltage/Constant Current Characteristic Similarly, crossover from the constant current to the constant voltage mode automatically occurs from a decrease in load. A good example of this would be seen when charging a 12-volt battery. Initially, the open circuit voltage of the power supply may be preset for 13.8 volts.

5. MAINTENANCE WARNING The following instructions are for use by qualified personnel only. To avoid electrical shock, do not perform any servicing other than contained in the operating instructions unless you are qualified to do so. 5-1 Fuse Replacement If the fuse is blown, the CV or CC indicators will not light and the power supply will not operate. The fuse should not normally blow unless a problem has developed in the unit. -

If readjustment is required, use the following procedure. Locations of the adjustments are shown in Fig. 5-1 and Fig. 5- (1) Adjustment of the Rating Voltage A. Connect an accurate (±0.1%) external multimeter to measure the DC voltage at output terminals of the power supply. - Page 20 Fig. 5-1 Adjustment Location...
