2. Install the mounting bracket (using the frame post as an example).
•Prepare the tightening screws according to the load-bearing structure. This document introduces
how to install the autotransformer on a wall as an example. The installation method on a support
is the same as the installation method on a frame post. Prepare M6 stainless bolt assemblies
(including flat washers, spring washers, and M6 bolts) with appropriate lengths as well as
matched flat washers and nuts based on the support specifications.
•Secure the mounting bracket using either of the following hole combining methods: 1. line
combination (1, 2, and 4); 2. staggered combination (1, 3, and 5).
•The autotransformer weighs about 13 kg.
