Goodrive170-PV Series Solar Pump Inverter Options
-60-
Note:
The cables recommended for the main circuit can be used in scenarios where the
ambient temperature is lower than 40°C, the wiring distance is shorter than 100 m,
and the current is the rated current.
If a control cable and power cable must cross each other, ensure that the angle
between them is 90 degrees.
If the inside of motor is moist, the insulation resistance is reduced. If you suspect the
inside of motor is moist, dry and re-measure the motor.
A.4 Reactor
When the distance between the inverter and motor is longer than 50 m, the parasitic
capacitance between the long cable and ground may cause large leakage current, and
overcurrent protection of the inverter may be frequently triggered. To prevent this from
happening and avoid damage to the motor insulator, compensation must be made by
adding an output reactor. When the inverter is used to drive multiple motors, take the total
length of the motor cables (that is, sum of the lengths of the motor cables) into account.
When the total length is longer than 50 m, an output reactor must be added on the output
side of the inverter. When the distance between the inverter and motor ranges from 50 m
to 100 m, select the reactor according to the following table. If the distance is longer than
100 m, contact INVT's technical support technicians.
Output reactor model selection:
Note:
The rated output voltage drop of output reactors is 1%±15%.
All the options in the preceding table are externally configured. You need to specify
whether the options are externally configured in your purchase order.
