PV500 series solar pumping inverters
● (+) and (-) are DC power supply input terminals. R, S and T (L,N) are AC power supply
input terminals. U, V and W are output terminals. Please connect the input power
cables and motor cables with proper techniques; otherwise the damage to the inverter
may occur.
1.3.2 Commissioning and running
●Disconnect all power supplies applied to the inverter before the terminal
wiring and wait for at least the designated time after disconnecting the
power supply.
●High voltage is present inside the inverter during running. Do not carry out
any operation except for the keypad setting.
●The inverter cannot be used as "Emergency-stop device".
If the inverter is used to break the motor suddenly, a mechanical braking
device should be provided.
Note:
● 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 to run it again before utilization.
● Cover the front board before running, otherwise electric shock may occur.
1.3.3 Maintenance and replacement of components
● Only qualified electricians are allowed to perform the maintenance,
inspection, and components replacement of the inverter.
● Disconnect all power supplies to the inverter before the terminal wiring.
Wait for at least the time designated on the inverter after disconnection.
Take measures to avoid screws, cables and other conductive materials to
●
fall into the inverter during maintenance and component replacement.
Note:
● Please select proper torque to tighten screws.
● Keep the inverter, parts and components away from combustible materials during
maintenance and component replacement.
● Do not carry out any isolation voltage-endurance test on the inverter and do not
measure the control circuit of the inverter by megameter.
1.3.4 Scrap treatment
●
●
There are heavy metals in the inverter. Deal with it as industrial
effluent.
When the life cycle ends, the product should enter the recycling
system. Dispose of it separately at an appropriate collection point
instead of placing it in the normal waste stream.
