 (+) 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 VFD may occur.
1.3.2 Commissioning and running
 Disconnect all power supplies applied to the VFD before the terminal
wiring and wait for at least the designated time after disconnecting the
power supply.
 High voltage is present inside the VFD during running. Do not carry out
any operation except for the keypad setting.
 The VFD cannot be used as “Emergency-stop device”.
If the VFD 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 VFD frequently.
 For VFDs 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 VFD.
 Disconnect all power supplies to the VFD before the terminal wiring. Wait
for at least the time designated on the VFD after disconnection.
 Take measures to avoid screws, cables and other conductive materials to
fall into the VFD during maintenance and component replacement.
Note:
 Please select proper torque to tighten screws.
 Keep the VFD, parts and components away from combustible materials during
maintenance and component replacement.
 Do not carry out any isolation voltage-endurance test on the VFD and do not measure the
control circuit of the VFD by megameter.
1.3.4 Scrap treatment
 There are heavy metals in the VFD. 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.
