FAQ

Q: What is a “mass terminal block”?
A: It is a high-density termination assembly that consolidates multiple field wires into a single connector interface, simplifying wiring and reducing installation time.

Q: Is this compatible with standard I/O cards?
A: Yes, when matched to the correct I/O card via the keying system and used within the Electronic Marshalling framework.

Q: Can I install this with power on?
A: No. De-energize system and field power before removal or insertion.

Installation Guidelines

1. Verify the rotary key position matches the I/O card.
2. Slide the terminal block onto the carrier until fully latched.
3. Route field cables through the cabinet gland and terminate per pinout diagram.
4. Torque screws to specification to prevent loosening under vibration.

Selection Tips

• Use KJ4001X1-CF1 when high-density 24-pin termination is required.
• Confirm your I/O card calls for the CF1 mass terminal block.
• For hazardous locations, verify ATEX markings on the product label.
