Troubleshooting Suggestions
1. Determine the position of the input
and output circuit breakers
associated with the ESC
corresponding to [ESR-CabinetNo
ESM-SlotNo].
2. Send a shutdown command, turn off
the battery switch, bus switch, and
AC power supply switch, and wait for
5 minutes.
3. Check whether the installation
position is well ventilated and
whether the ambient temperature
exceeds the upper limit. If the
ventilation is poor or the ambient
temperature is too high, improve the
ventilation and heat dissipation,
check whether the copper bar is
properly connected, or check whether
the air conditioner is running
properly.
4. Turn on the AC power supply switch,
battery switch, and bus switch in
sequence to deliver a startup
command.
5. If the alarm persists, contact your
dealer or technical support.
