Selection & installation notes
- Do not run a standard 2 A-fused branch at the 10 A hardware limit. Select protection for the load, conductor and approved module configuration; never increase fuse size solely to stop nuisance operation.
- Observe the 30 A total-input limit. Terminal component voltage ratings do not raise the module’s stated 5/12/24 VDC working-voltage options.
- The source lists inconsistent AWG/mm² limits, including 12 AWG and 2.5 mm² on the branch side. Obtain the exact terminal wire specification before wiring.
- Isolate power before wiring or replacing fuses. Clear the fault first and fit an approved fuse of the required rating; never bridge a fuse with wire.
- Use the specified 1.2 N·m supply and 0.5 N·m branch terminal torque. Confirm rail retention and avoid vibration, corrosive gases, dust and direct sunlight.
- Dimensions and masses are reference values. Request the installation drawing for customized versions.
