FAQ

Q: Can I cut or extend this cable?
A: No. The 0.8 m length is fixed. Do not attempt to modify the cable assembly.

Q: Can I disconnect this while the system is running?
A: No. Disconnecting the LocalBus extender cable during active operation causes immediate downstream I/O dropouts and CPU fault states.

Q: How many cables can I use in one system?
A: The total combined length of carriers and extenders must not exceed 6.5 meters.

Installation Guidelines

1. Position adjacent horizontal carriers within 0.8 m of each other.
2. Align the 44-pin male connector to the female receptacle on the carrier.
3. Press firmly until the connector locks; avoid tight bends or tension on the cable.
4. Secure the cable with strain relief to prevent fatigue at the connector.

Selection Tips

• Order KJ4002X1-BF3 when you need to link two horizontal carriers with a 0.8 m bottom cable.
• Verify carrier spacing in your cabinet drawing before installation.
• For longer runs, use LocalBus extenders (HB1/NB1) rather than multiple cable assemblies.
