Installation Guide

1. Power down the associated IOP and verify zero energy state before installation.
2. Mount the FTA in the designated Size B position within the cabinet.
3. Connect field wiring to the compression terminals according to the channel assignments.
4. Install the interconnect cables to the IOP(s).
5. Apply power and verify channel status indicators and signal integrity.

Selection Tips

• Choose this model when enhanced transmitter power conditioning and individual channel protection are required.
• Confirm CE compliance and conformal coating needs for the installation environment.
• Verify IOP compatibility (high-level analog input processor) before ordering.
