4. Installation & Wiring

1. Pre‑Installation: Disconnect 24 VDC power; ensure DIN rail is properly grounded.

2. Mounting: Snap module onto a standard 35 mm DIN rail and lock in place.

3. Power: Connect 24 VDC to PWR1/PWR2 terminals; dual‑redundant power recommended.

4. Ethernet:

   • Copper: Use CAT5e/CAT6 cables for RJ45 ports.

   • Fiber: Insert certified 100 Mbps SFP transceivers and connect single‑/multi‑mode fiber.

5. Grounding: Connect chassis ground to system earth for ESD/EMI protection.

5. Operation & Diagnostics

• Power LEDs: PWR1/PWR2 (green) = power OK.

• Fault LED: FAULT (red) = power failure, port error, or hardware fault.

• Port LEDs: LINK/ACT (yellow) = link up; flashes during data transfer.

• Management: Configure and monitor via web UI, CLI, or Ovation workstation tools.

6. Maintenance & Safety

• Maintenance: Inspect connections periodically; update firmware for optimal performance.

• Safety: Disconnect power before servicing; use only certified cables and transceivers.

• Operating Limits: Keep within rated temperature/humidity ranges to avoid damage.

7. Product Status

• Current Status: Active production; new original and refurbished spares available.

• Compatibility: Fully interoperable with all modern Ovation DCS releases.
