Goodrive300-LIFT series inverter
Safety precautions
-3-
Prevent screws, cables, and other conductive items from dropping into the inverter.
The leakage current of the inverter may be larger than 3.5 mA during operation. Perform reliable
grounding and ensure that t
he grounding resistance is lower than 10 Ω. The conductivity of the
PE grounding conductor is the same as that of the phase conductor (with the same sectional
area).
R, S and T are the power input terminals, while U, V and W are the the terminals for output to the
motor. Connect the input power cables and motor cables properly. Otherwise, damage to the
inverter may be caused.
1.4.2 Commissioning and operation
Before wiring the terminals of the inverter, disconnect all power supplies
applied to it and wait for at least the waiting time specified on it..
The voltage is high inside the inverter when it is running. Except settings
through the keypad, do not perform any other operations on it.
The inverter cannot be used independently as an "emergency-stop device".
The product cannot be used for motor emergency braking. You need to
configure a mechanical brake device.
When the inverter is used to drive a permanent-magnet synchronous motor
(PMSM), ensure the following in addition to the preceding precautions:
1.
All the input power supplies, including the main power supply and
control power supply, are disconnected.
2.
The running of the PMSM is stopped, and the voltage on the output
side of the inverter is lower than 36 V.
3.
The waiting time after the PMSM is stopped is not shorter than the
waiting time specified on the inverter, and the voltage between (+) and
(-) is lower than 36 V.
4.
During the operation, ensure that the PMSM will not rotate again due
to external loads. It is recommended that you configure an effective
external brake device or disconnect the electrical connection between
the PMSM and the inverter.
Note
:
Do not switch on or off the input power supply of the inverter frequently.
If the inverter has been stored for a long time, check, set the capacity of, and perform a test run
on it before using it. For details about inspection and capacity setting, see chapter 9.
"Maintenance and hardware fault diagnosis".
Close the front cover of the inverter before running it. Otherwise, electric shocks may be caused.
