4. Connect the ground cable, power cables, and signal cable. Signal cable The number of cables in the figure is for reference only. If the mains input and bypass input share a power source, you do not need to connect bypass input cables.
Verifying the Installation 1. Check that there is no foreign matter at the top and bottom of the cabinet, copper bars, switches, and the rear of units. 2. After verifying the installation, reinstall all the covers. 3. (Remove the paper protective film from the sealing putty.)
