KENO Railing Installation Instructions for Photovoltaic Modules

Introduction and General Information

The installation system described is used to fix photovoltaic modules to balcony railings in a horizontal orientation, parallel to the railing. The design is compatible with modules from 1134 mm to 1140 mm wide and up to 2278 mm long.

KENO strives to ensure a top-quality and easy-to-install product. These instructions serve as a guide for the correct installation of structure components but do not replace a professional design. The installer must be suitably trained and qualified, bearing full responsibility for correct installation and choosing the appropriate construction type.

Installation Steps

1. Step 1: Protect Railing

   As a first step, it is recommended to cover the elements K-74-03 and K-74-02 with an EPDM pad to protect the railing from damage.

   Diagram 1: Protection K-74-03 - A U-shaped bracket with an EPDM pad on the inner surface, labeled K-74-03. Diagram 2: Protection K-74-02 - A flat bar with two elongated slots and an EPDM pad along the top edge, labeled K-74-02.
2. Step 2: Pre-screw K-74-01 and K-74-03

   Pre-screw the components K-74-01 and K-74-03 together. Use one of the two prepared holes to select the mounting height for the module on the railing. Bolt these components together using a K-76-20 carriage bolt and a K-21 nut.

   Diagram 3: Bolting of elements K-74-01 and K-74-03. Shows K-74-01 (a vertical mounting bracket) being attached to K-74-03 (a U-shaped bracket) using a K-76-20 carriage bolt and a K-21 nut. Two possible mounting heights are indicated by different holes.
3. Step 3: Attach Flat Bar K-74-02 to Hook K-74-01

   Pre-bolt the flat bar K-74-02 to the hook K-74-01 using the carriage bolt K-76-20 and nut K-21. Use the appropriate hole to fit the assembly to the railing.

   Diagram 4: Bolting of flat bar K-74-02 with hook K-74-01. Shows K-74-02 (flat bar) being attached to K-74-01 (vertical bracket) using a K-76-20 carriage bolt and a K-21 nut. Two views (A and B) show the connection points.
4. Step 4: Bolt Module to Hooks

   Bolt the module to the two pre-screwed hooks according to points 1 and 2. Use four K-18-20 Allen screws, four K-51-M8 washers, and four K-21-M8 nuts.

   NOTE: Use the manufacturer-prepared holes in the module frame to screw the module in place.

   Diagram 5: Installation of module (view I). Shows a photovoltaic module being attached to two K-74-01 brackets. The connection uses K-18-20 Allen screws, K-51-M8 washers, and K-21-M8 nuts. Diagram 6: Installation of module (view II). Shows a close-up of the module frame attachment points.
5. Step 5: Tighten Allen Bolts

   The Allen bolts must be tightened to a torque of 18 [Nm].

6. Step 6: Position Structure on Railing

   Place the structure over the railing in such a way that the K-74-03 element leans against the railing.

   Diagram 7: Installation of the structure on the railing. Shows the assembled module and brackets being placed onto a railing, with the K-74-03 element leaning against the railing.
7. Step 7: Pre-screw K-74-01 Elements to Railing

   Pre-screw the K-74-01 elements to the railing using the flat bars K-74-02. This is done using four K-76-100 carriage bolts and K-21 nuts.

   NOTE: It is permissible to use any two holes in the flat bar and to arrange the flat bars at an angle if the design of the railing requires this.

   Diagram 8: Installation of flat bar K-74-02 on the other side of the railing (view I). Shows K-74-01 elements being attached to the railing using K-74-02 flat bars, K-76-100 carriage bolts, and K-21 nuts.
8. Step 8: Install Safety Bolt

   Place the K-28-60 hexagonal bolt in the prepared hole in the K-74-03 element and screw it on the opposite side with the K-21 nut. The purpose of this bolt is to protect the structure from falling.

   Diagram 9: Installation of the safety bolt. Shows a K-28-60 hexagonal bolt being inserted through K-74-03 and secured with a K-21 nut to prevent falling.
9. Step 9: Final Torque Specification

   All bolts with M10 threads must be tightened to a torque of 30 [Nm].
