TRANSFER SWITCH
The Automatic Transfer Switch supplied with the Home
Generator System is enclosed in a NEMA Type 1 enclosure
suitable for indoor use only. Guidelines for mounting the
Automatic Transfer Switch include:
• Install the switch on a firm, sturdy supporting structure.
• To prevent switch contact distortion, level the switch if
necessary.This can be done by placing washers between
the switch enclosure and the mounting surface.
• NEVER install the switch where water or any corrosive
substance might drip onto the enclosure.
• Protect the switch at all times against excessive moisture,
dust, dirt, lint, construction grit and corrosive vapors.
The typical Automatic Power Transfer Switch is depicted in
Figure 12. It is best if it is mounted inside near the main
distribution panel, as shown. Discuss layout
suggestions/changes with the owner before beginning the
system installation process.

Generator AC Connection System
A single-phase, three-wire AC connection system is used in
the Home Generator System.The stator assembly consists
of a pair of stationary windings with two leads brought out
of each winding.The two windings are connected together
in series, resulting in a fixed 240 Volt AC, 60Hz output.
Stator output leads 11 and 44 are the two "hot" leads; the
junction of leads 22 and 33 forms the neutral lead, as
shown schematically and as wiring diagram in Figure 13. A
complete schematic and wiring diagram can be found in the
owner's manual.
