1.2 When power is applied
WARNING
z Do not attempt to install or remove input or output connectors of inverter when the
power supply is turned on. Otherwise, the inverter may be damaged due to the surge
peak caused by the insertion or removal of power.
z When momentary power loss is longer than 2 seconds (the large of horse power, the
longer of time), the inverter does not have enough storage power to control the circuit;
Therefore, when power is regenerated, the operation of the inverter is based on the
setup of F_10 and the condition of external switch, this is considered to be「restart」
in the following paragraphs.
z When the momentary power loss is short, the inverter still has enough storage power to
control the circuit; therefore, when power is regenerated, the inverter will automatically
start operation again depends on the setup of F_23.
When restart the inverter, the operation of the inverter is based on the setup of F_10
and the condition of external switch (FWD/REV button). Attention: the restart
operation is irrelevant with F_23/F_24.
(1) When F_10=0, the inverter will not start after restart.
(2) When F_10=1 and the external switch (FWD/REV button) is OFF, the inverter will
not start after restart.
When F_10=1 and the external switch (FWD/REV button) is ON, the inverter will start
automatically after restart. Attention: Base on safety reason, please turn off the external
switch (FWD/REV button) after power loss to avoid possible damage to the machine and
the human body after sudden regeneration of power.
Warning
Warning! E2 series built in Filter type leakage current can exceed the IEC standard limit of
3.5mA. Please ground the inverter as shown in figures 3.5 and 3.6.
Operation with ungrounded supplies:
1. Filtered inverters CANNOT be used on ungrounded supplies.
2. Unfiltered inverters can be used on ungrounded supplies. If any output phase is shorted
to ground, the inverter may trip with OC.(over current trip)
Operation with Residual Current Device(RCD):
1. A filtered inverter with the trip limit of the RCD is 300mA
2. The neutral of the supply is grounded, as is the inverter.
3. Only one inverter is supplied from each RCD.
