soon as possible in order to prevent wear and unnecessary power consumption.

The output will be cut off if the short-circuit occurs between the positive and the negative output
terminal, which prevents power loss. The device will resume normal operation when the problem has
been solved.

This device is a large power source. The device should be well-ventilated when working at max.
power in order to avoid overheating. Keep in mind that the surface of the heat sink is too hot to
touch when the device is being used at max. power.

Improper operation of the device and an excessive ambient temperature may cause certain internal
components to fail. When this happens, the actual output voltage may exceed the rated output
voltage. Proceed with caution when using this device and avoid unnecessary damage to the load.

6. Operation
1. Connect a load (electrical equipment, etc.) to the power supply output, and pay attention to the
polarity. Do not reverse the polarity!
2. Plug the AC input power cord into a suitable AC power jack.
3. Place the power switch to the ON position. The power indicator lights and the power has been
turned on.
4. Make sure the load current is less than the rated output current of the power supply. 80 % of the
rated output current is recommended as the maximum current.
7. Cleaning and Maintenance

Disconnect the device from the mains prior to maintenance activities.

The power supply cables must not show any damage. Have a qualified technician maintain the
device.

Wipe the device regularly with a moist, lint-free cloth. Do not use alcohol or solvents.

There are no user-serviceable parts, apart from the fuse. Contact your dealer for spare parts if
necessary.

Store the device in a dry, well-ventilated, dust-free room.
