1.1.2 During Power up
Danger
z
The inverter still has control power
immediately
after
power loss. When the power is re-
supplied, the inverter operation is controlled by F41.
z
The inverter operation is controlled by F04 and C09 and the status of (FWD/REV RUN
switch) when power is re-supplied. (F39 /F40) Power loss ride
through
/ Auto reset after
fault
)
.
1. When F04=000, the inverter will not auto restart when power is re-supplied.
2. When F04=001 and operation switches (FWD/REV RUN) is OFF, the inverter will not
auto restart when power is re-supplied.
3. When F04=001and operation switch ON and C09=000, the inverter will auto restart
when power is re-supplied. Please turn OFF the run ( start) switch to avoid damage to
machine and injury to
personnel
before the power is re-supplied.
z
When C09=000 (direct start on power up), please refer to the description and
warning for
C09
(Page 4-27)
to verify the safety of operator and machine.
1.1.3 Before operation
Caution
Make sure the model and
inverter
capacity
match the
F00
setting (Page 4-12)
.
1.1.4 Leakage current
Warning
Warning! EV 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 inverter
s
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 300
mA
2.
The neutral of the supply is grounded,
as is
the inverter.
3.
Only one inverter is supplied from each RCD.
