SEOQandA_Product

question:How to resolve loose connections in ZIA 1.5/3L-1S/16/KB terminal blocks?
answer:Check and tighten screw terminals. Ensure proper wire insertion and use correct torque (0.6–0.8 Nm) to secure connections.
question:Why does the terminal block overheat during operation?
answer:Verify load current does not exceed 16A. Check for poor contacts, damaged terminals, or undersized wiring and replace if necessary.
question:How to fix incorrect wire seating in the terminal block?
answer:Use stripped wire length of 9–11mm. Ensure wires are fully inserted into the clamp area before tightening screws.
question:Why does the terminal block fail to maintain electrical continuity?
answer:Inspect for corrosion, debris, or oxidation. Clean contacts with a suitable solvent and ensure proper clamping force.
question:How to address terminal block labeling confusion during installation?
answer:Refer to the pinout diagram on the terminal block. Use a multimeter to verify connections if markings are unclear.
