.10.
3. Disassembly and installation
●Only qualified electricians are allowed to operate on the drive device/system.
Ignoring the instructions in “warning” may cause serious physical injury or death or
property loss.
●Connect the input power lines tightly and permanently. And ground the device with
proper techniques.
●Even when the inverter is stopped, dangerous voltage is present at the terminals:
- Power Terminals: R, S, T
- Motor Connection Terminals: U, V, W.
●Stop the drive and disconnect it from the power line. Wait for 10 minutes to let the
drive discharge and then begin the installation.
●Minimum cross-sectional areas of the grounding conductor should be at least 10m².
Or select the larger one between the cross-sectional area of the power cord
conductors and the cross-sectional area of the grounding conductor according to the
following table:

●Life the inverter by its base other than the keypad or the cover. The dropping of the
main part may cause physical injury.
●The inverter is fixed on a non-flammable wall such as metal and away from heat and
flammable materials to avoid the fire.
●If more than two drives are installed in a cabinet, the temperature should be lower
than 40
℃
by means of a cooling fan. Overheat may cause fire or damage to the
