The procedure required to install the 5- or 25-unit G6 multi-charger on a vertical surface.

1. Slide the two mounting brackets onto the central bar. Ensure the brackets fit snugly into the grooves on the outside of the central bar.
   
2. Using the measurements provided, mark the areas where the screws will go.
   
3. Using a drill bit appropriate for the surface you are drilling into, drill into the surface, using your marks as guides. Ensure the holes are the appropriate length for your anchors (not provided).
4. Insert anchors that are appropriate for your mounting surface. For example, if you are mounting on a wall, use drywall anchors.
5. Have one person hold the assembled mounting unit on the wall, lining up the screw holes with the holes you drilled.
6. Place a level along the central bar to ensure the mounting unit is even.
7. Use a screwdriver to insert the provided screws through the mounting unit into the wall, as shown in step 1.
8. Line up the multi-unit charger’s bottom keyholes with the hooks on the mounting unit.
9. Slide the charger toward you to lock it in place.
10. Use a screwdriver to insert the provided screws through the tabs on the back of the charger into the bracket.
    
11. Plug the 24V AC/DC adapter into the 24V DC input port on the back of the multi-unit charger, then attached the supplied AC power cord to the 24V AC/DC adapter.
    
12. Plug the AC power cord in to an AC outlet with a voltage within the AC input range of the adaptor.
13. If your setup allows, place the charging block on the shelf at the back of the mounting unit (behind the multi-unit charger) to prevent tension on the charging cables.
