between switching is at least one hour since frequent charge and discharge will shorten
the service life of the capacitor inside the AC drive.
When a contactor is installed between the output side of the AC drive
and the motor,
do not turn off the contactor when the AC drive is active. Otherwise, modules inside the
AC drive may be damaged.

drive are switched on or off. If the inductive loads generate a very high surge voltage,
use a surge suppressor for the inductive load or also use a diode.
Note
Do not connect the surge suppressor on the output side of the AC.
13 Altitude and de-rating
In
places where the altitude is above 1000 m and the cooling effect reduces due to thin
air, it is necessary to de-rate the AC drive. Contact Inovance for technical support.
14 Some special usages
If wiring that is not described in this manual such as common DC bus is applied,
contact the agent or Inovance for technical support.
