Safety & Warnings
The manual includes the following safety warnings and precautions:
1. The units must be used within their specified range. Before plugging into the AC supply outlet, check whether the input rating conforms with your local supply. For certain models, a voltage selector is available, and it should be switched to the appropriate position before use.
2. The power supply is a floating type. For ordinary use, ensure that the MASTER/SLAVE switch on the rear panel is set to the MASTER position and either the (+) output terminal or the (-) terminal is connected to the GND terminal (chassis GND) via the shorting bar.
3. The unit should be used within the specified ambient temperature range listed in the specification table.
4. Since the unit is cooled by natural convection, do not place objects on top to block the convection. Avoid placing the unit on or near any heat-emitting devices or using multiple units in a stacked configuration. For best results, use the unit in an environment that is as well cross-ventilated as possible.
