How to Install the ABB LD38-4 Coil Terminal Block
Step-by-step guide to mounting and wiring the LD38-4 terminal block for AF26–AF38 contactors.
Estimated time: 15m
Tools needed:
Flat Ø6.5mm or Pozidriv 2 screwdriver
Supplies needed:
Mounting screws (if not pre-installed), Conductors (2.5–25 mm²)
- Position the terminal block
Align the LD38-4 terminal block with the bottom access point of the AF26–AF38 contactor. Ensure the block is oriented correctly for bottom access to coil terminals.
- Secure the terminal block
Mount the terminal block using the provided mounting points or compatible screws. Tighten securely to ensure stable positioning.
- Prepare conductors
Strip the insulation from the conductors to a length of 14 mm. Ensure the conductor size matches the supported range (2.5–25 mm² for rigid or stranded conductors).
- Connect conductors
Insert the conductors into the tunnel terminals and tighten the screws to a torque of 2.5 Nm (22 lb.in). Verify that all connections are secure and properly seated.
- Verify installation
Check that all terminals are tightened, unused terminals have screws tightened, and the terminal block is properly aligned. Ensure no loose wires or exposed conductors remain.
