ABB PPD513 AC 800M DIN rail mounted controller

ABB PPD513 requires extra caution when installing AC 800M and S800 I/O units onto DIN rails to ensure mechanical stability, effective grounding, and electrical safety.Here’s a step-by-step guide based on the provided instructions:

PPD513 Mounting on Metal Sheet:

1. Requirements: Use an unpainted metal sheet at least 2.5 mm thick and 180 mm high, with preferably one side bent 90 degrees for stability.
2. Fastening DIN-rail: Mount DIN-rail on the metal sheet with fastening screws every 100 mm for mechanical stability and good grounding.
3. Cabinet/Rack Fastening: Fasten the metal sheet to the cabinet or rack with self-tapping screws, ensuring good grounding connection.
4. DIN-rail Type: Use DIN-rail type NS 35/7.5 with a height of 7.5 mm, according to standard EN50022.
5. Electrical Contact: Ensure good electrical contact to the chassis for all bolted joints.

PPD513 Mounting on Prefabricated Aluminum Profile:

1. Requirements: Use aluminum profiles suitable for horizontal or vertical mounting, providing excellent grounding and rigid mounting.
2. Fastening to Cabinet: Fasten the aluminum profile to the cabinet with at least 4 self-tapping screws.
3. Screw Grooves: Utilize grooves in the profile for screws, especially in environments with excessive vibrations.
4. Profile Sizes: Select aluminum profiles of appropriate sizes for horizontal or vertical mounting based on available options.

Mounting and Removing Units:

1. Read Instructions: Carefully read the installation instructions provided with the equipment before mounting any processor unit or communication interface.
2. Single Unit Mounting: Since electronic unit and base plate are supplied as a single unit, there’s no need to separate them during mounting.
3. Mounting Procedure: Use a blade screwdriver that fits securely into the locking screw (1 mm slot) to mount the units onto the DIN-rail.

Ensure all conductive structural components are bonded together with good and permanent connections for electrical safety and EMC reasons. Use self-tapping cutting head screws for bonding, remove paint from contact surfaces on painted surfaces, and apply conductive grease for permanent connection. Properly connect the cabinet/rack to protective earth/ground for safety.
