Follow-up Procedure

To enhance the corrosion resistance of a ground terminal, apply silica gel or paint around the
terminal after connecting the PE cable.

5.5 Installing Router Cables

The SmartACBox is not factory-installed with a router, so you need to purchase and install a
router by yourself.

This document introduces how to install cables for an SC-RRX230 or SC-RRX280 router
produced by SUN DENSI in Japan.
