4. Installation & Operation Guidelines

1. Standard Wiring Operation Steps

   Step1: Fully cut off power supply of all DCS rack modules before plugging/unplugging the cable to avoid signal short circuit and permanent burnout of I/O boards

   Step2: Align the 37-pin D-Sub pin interface with FBM baseplate / terminal assembly port, fully insert and tighten both side locking screws to prevent loose contact during long-term vibration

   Step3: Separate P0916FQ signal cable from high-current power cables, maintain ≥15cm isolation distance inside control cabinets to reduce crosstalk interference

   Step4: Fix cable body with soft plastic cable ties, avoid excessive tension pulling connectors to prevent internal wire fracture; reserve sufficient slack for cabinet door switching

   Step5: Complete all wiring work, restore power supply and run system self-test to verify communication stability and analog signal accuracy

2. Full Compatibility List

   FBM Modules: FBM201, FBM202, FBM207/B/C, FBM211, FBM212, FBM217, FBM219, FBM241/B/C/D, FBM242

   Matching Terminal Assemblies: RH916UY, RH916AQ, RH916AR, RH916AE and all RH916 series DIN rail TAs

   Control Processors: P0916EV, CP40B, CP60, CP30

3. Daily Maintenance Specifications

   • Strictly prohibit hot plugging under live circuit status

   • Inspect connector pin oxidation, sheath abrasion and wire aging every 6 months

   • Do not arbitrarily cut, splice or replace with non-original third-party connectors

4. Safety Warning

   Unauthorized cutting, splicing or non-original connector replacement will cause severe signal attenuation, communication disconnection and permanent damage to I/O modules, and void the official product warranty.

5. Packaging & Warranty Terms
