Safety Precautions
1-2
1.1.2 During Power up
Danger
The
iDrive
still has control power if the time of power loss is very short. When the power
is re-applied, the inverter operation is controlled by parameter b31.
The
iDrive
operation is controlled by parameters A00, b31, b32 and b33 and the status of
any FWD/REV RUN switch. Please be sure to consider the following settings: -
1. When A00=000, the inverter will not auto restart when power is re-applied.
2. When A00=001 and operation switches FWD/REV RUN are OFF, the inverter will not
auto restart when power is re-applied.
3. When A00=001 and operation switch ON and b33=000, the inverter will auto restart
when power is re-applied. Please turn OFF the run (start) switch to avoid potential
damage to machine and injury to operator before the power is re-applied.
When b33=000 (direct start on power up), please refer to the description of b33 to verify
the safety of operator and machine.
1.1.3 Before operation
Make sure the model and capacity are the same as that set in parameter b89
1.1.4 Earth / ground leakage current
WARNING
Warning!
iDrive
models with built-in EMC filter can give leakage current > 3.5mA.
ALWAYS ENSURE INVERTER IS CORRECTLY EARTHED / GROUNDED.
Follow instructions given in Section 3 of this manual in ALL installations.
•
DO NOT
use
iDrive
EDX
inverters on ungrounded (floating) power supplies.
•
iDrive
should be used in fixed installations only.
Operating
iDrive
EDX
with Residual Current Device (RCD):
1. Leakage current may cause nuisance trip when RCD setting is <200mA
2. Only one inverter should be supplied from each RCD.
Caution
