Installation Instructions

1. Preparation
   Ensure that all wiring is de-energized. Check the system documentation for the proper slot location of the F3304 module within the rack.

2. Mounting the Module
   The module is designed for vertical installation in a 19-inch rack or on DIN rails. Slide the module into the correct slot and ensure the backplane connector is properly engaged.

3. Electrical Connection
   Connect the field wiring to the designated terminals using shielded cables where applicable. Tighten terminal screws to avoid loose connections.

4. Configuration
   Use HIMA’s configuration software (e.g., ELOP II or SILworX) to configure the module settings such as channel function, fault detection logic, and redundancy.

5. Diagnostics Check
   Power on the system and verify that all diagnostic LEDs indicate normal operation. Address any fault codes as specified in the user manual.

6. Hot Swap Feature
