Landmark MG21, Быстрый старт

Страница: 5 / 10

5
Cautions:
A. The inverter power should go directly from the power supply as shown in Fig. 4. The 12V from
the connector CN5 cannot carry the heavy inverter current load to run the VHB backlight.
B. Never connect or disconnect any parts of the system while the power is turned on as doing so
may cause serious damages to the MG21 controller and other parts.
