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.

3. Install the autotransformer on the

mounting bracket. 4. Tighten the screws.

The specifications of the pipes should comply with those of the cable glands. For example, for a 3/4 in.

waterproof block, a 3/4 in. pipe is recommended. The pipe appearance shown in the following figure is

for reference only. The actual pipes prevail.

•When connecting the cable, ensure that the exposed core wire is totally inserted into the cable hole

and connected securely. Failing to do so maycause the autotransformer malfunction and damage.

•In the following figure, 1.0 mm x 5.5 mm (0.04 in. x 0.22 in.) indicates the thickness and width of

the screwdriver blade.

4Installing the PE Cable and Cover

•Before closing the cover, check that the cables are correctly and securely connected. Then

take proper measures to ensure that the pipe conduits and fittings are reliably secured. Seal

cable holes to ensure that the cover and sealing washer are intact and free from any foreign

objects. Clean the foreign objects in the maintenance compartment if there is any.

•If the screws on the enclosure door are lost, obtain the spare screws from the fitting bag.
