3.12 Operation
3.12.1 Check and preparation before operation
Before the start of operation shall examine the following several aspects:
1. Check the wiring is ture or not. Especially check ac motor driver output terminals (V, U, W)
cannot be connected to the power, confirm grounding terminals ground well.
2.
Confirm the terminal or the exposure of charged have short circuit or not.
3. Confirm terminal connections, plug connector (optional) and screw fastening are all fastening or
not.
4.
Confirm motor have not connect the mechanical device.
5. All switch must disconnected before power on. Ensure the inverter won't start and without
abnormal action when power on.
6. Turn on the power must after cover installation.
7. Wet hand prohibit operation switch.
8. Ensure the following several aspects after power on:
1). Keyboard panel should be shown no fault.
(1). If the keyboard panel is not chosen, the
indicating lamp of
POWER
is lit, and
indicating
lamp of
ALARM
is not lit
。
(2). If the keyboard panel is n chosen, the
indicating lamp of
and
are all lit
。
2). The cooling fan which installed inside inverter (the type which including the fan) must be
