Please be careful and don’t connected the auxiliary terminal to the voltage or current
line by mistake, to avoid damage to meter.
9. Check connecting wire carefully and avoid any error (such as the reverse wiring for the
incoming and outgoing lines, the wrong connection of live and neutral, the bad fixing of
screws).
To ensure the correct wiring, it is recommended to use the appropriate testing tools
(such as multi-meters) for input/output test.
10. Close the terminal cover, and sealed it.
Please make sure that the terminal cover is closed tightly, otherwise it will cause the
meter relay cut off due to terminal cover open.

Switch on the breaker
Check the meter display, if there is any malfunction indication, phase inverse, cover open,
or strong magnetic field, no current indictor.
Press button to display voltage value, check the voltage twice.
Check the relay is on the right position (if the symbol ‘ ’ is shown on the LCD).
21.5 Un-installation
1. Switch off the breaker and power off the meter.
Make sure that the power is cut off before the meter un-installation, otherwise it will
cause a threat to life. The fuse should be disconnected and put it in a safe place to avoid
the accidental power-on.
