Goodrive170-PV Series Solar Pump Inverter Safety precautions
-3-
(+) and (-) are DC power supply input terminals, R, S, and T are AC power supply
terminals, while U, V and W are the output motor terminals. Connect the input power
cables and motor cables correctly; otherwise, damage to the inverter may occur.
1.3.2 Commissioning and running
Cut off all power supplies connected to the inverter before terminal
wiring, and wait for at least the time designated on the inverter after
disconnecting the power supplies.
High voltage presents inside the inverter during running. Do not carry
out any operation on the inverter during running except for keypad
setup.
The inverter cannot be used as an "Emergency-stop device".
If the inverter is used to brake the motor suddenly, a mechanical
braking device shall be provided.
Do not switch on or off the input power supply of the inverter frequently.
For inverters that have been stored for a long time, check and fix the capacitance
and try pilot run first before actual application.
Close the front cover before running the inverter; otherwise, electric shock may
occur.
1.3.3 Maintenance and component replacement
Only well-trained and qualified professionals are allowed to carry out
maintenance, inspection, and component replacement of the inverter.
Disconnect all power supplies of the inverter before terminal wiring and
wait for at least the designated time after disconnecting the power
supply.
Take proper measures to prevent screws, cables and other conductive
objects from falling into the inverter during maintenance and
component replacement.
Use proper torque to tighten screws.
Keep the inverter and its parts and components away from combustible materials
during maintenance and component replacement.
Do not carry out any insulation voltage-endurance test on the inverter or measure
the control circuit of the inverter by megameter.
