Warning
Warning:
Don’t plug or unplug the P1&P2&P3 terminal block to avoid drive damage or injury when
DM542T(V4.0) is powered on.
3.4 LED Light Indication
There are two LED lights for DM542T(V4.0). The GREEN one is the power indicator which will be always on generally.
The RED one is a protection indicator which will flash 1-2 times in a 3-second period, when protection enabled for a
DM542T(V4.0). Different number of flashes indicates different protection type (read section 11 for detail).
