Q: How do I identify if the wiring for the CT is connected in the correct direction?
A: Apply power to the device but don’t output the current yet. Observe the input voltage and current wave on the HMI to check if the two waveforms are in the same direction. If the waveforms go in different directions, the wiring direction of the CT is incorrect. See the example below.
Q: How do I set up the APF2000 and SVG2000 for parallel connection?
A: For multiple APF2000 or SVG2000 applications, the user must first calculate the total capacity that this system can provide. However, the total capacity of the two series must be calculated separately. Do not add two series together for the total capacity calculation. See the example below to calculate the total capacity:
Example 1: APF2000 (50A) + APF2000 (200A) + APF2000 (300A) = total capacity 550A
Example 2: SVG300A43A (300kVar = 433A) + SVG500A43A (500kVar = 722A) = total capacity 1155A
