The Computer-8d-96 has a standard DIN 43 700 cut-out size of 92+0.8 x 92+0.8 mm .
: Connect the phase supply voltage to the auxiliary power input terminals. Ensure the voltage matches the rating on the device label.
Cause: The system current is below the threshold measurement limit (100mA), or the C/K value is set too high.
If you have landed on this page, you likely have a dusty 8D96 on a panel door, blinking an error code, or you are trying to wire a replacement. You need the complete manual—not just a quick start guide, but the full technical specification, wiring diagrams, programming sequences, and troubleshooting flowcharts. Cause: The system current is below the threshold

Monitor step switching cycles. If a step chatters (constantly switches on and off), recalculate your factor or increase the connection delay time.
Circutor (the Spanish manufacturer) has discontinued the 8D96 series, replacing it with the Computer Max and Computer Plus lines. However, they maintain a legacy archive. Do not fall for scam sites charging $29 for a PDF. Here are the legitimate sources:
Configures the internal logic sequence according to the distribution scaling of your connected capacitor blocks. Standard Scaling Ratios: 1:1:1:1 (All stages share identical kvar output sizing).
