Installation & Wiring Guidelines

Proper installation and wiring are key to getting the best performance from your NaiHang power distribution block. Here’s a quick guide to help you set it up safely and efficiently.

Wire Termination:

• Strip the input and output wires to the recommended length, typically around 10–12 mm, to ensure a secure connection.
• Use a torque wrench to tighten the terminal screws to the specified torque, usually between 2.5 to 3.5 Nm, preventing over-tightening or loose connections which could cause faults.

Cable Compatibility:

• The distribution block supports both copper and aluminum conductors, making it versatile for various wiring standards globally.
• Always check wire gauge compatibility: input wires generally accept larger gauges for high current loads, while output terminals fit smaller sizes suitable for branch circuits.

Mounting Instructions:

• For DIN rail mounting, simply snap the block onto a standard 35mm DIN rail, ensuring it locks firmly in place. This quick snap-on feature speeds up installation and allows easy reconfiguration.
• For panel mounting, use the screw-down method to secure the block onto a flat panel surface. This option offers strong vibration resistance ideal for industrial environments.
