Cabinet wiring: 99.8% accuracy, color coding to GB 7947

Control wiring: how 99.8% accuracy is achieved

Cabinet wiring sets your commissioning time. Get three things right — pre-marked wire numbers, planned routing, and crimp torque — and the accuracy rate holds.

Harness preparation and crimping

Wiring process highlights

• Wire marking: automated wire marking machine, printed wire by wire against the secondary drawing;
• Color coding: per GB 7947 (yellow-green = PE, light blue = N, yellow / green / red = L1 / L2 / L3);
• Crimping: hydraulic and electric tools set to nominal torque, with pull tests on critical terminals;
• Routing: straight runs, large-radius bends at corners, neatly bundled.
