WARNING
1.Cut all power before connecting device.
2.Do not connect the current measurement inputs
directly to the current source. Always connect
the current source using a current transformer.
3. Once the device is energized, do not remove
the front panel.
4.Do not attempt to clean the device with a
solvent or another similar agent. Use only a dry
piece of cloth.
5.Check the correct connections before energized
the device.
6.To prevent potential fire shock hazard, do not
exposed the instrument to rain or moisture.
7.Do not open the instrument under any
circumstances when it is connected to power source.
8. Contact your authorized seller in case of any
problems with your device.
9.Device is only for panel mounting.
WARRANTY
Device has a two year warranty. Any repairs on the
device must be done only by manufacturer.
Otherwise, the device warranty will be void.
