SECTION 4: INSTALLATION AND WIRING
4.1 General
Eaton ATSs are factory wired and tested. Installation requires sol-
idly mounting the enclosed unit and connecting the power cables
and the auxiliary sensing circuits. Physical mounting procedures
and power cable connections are covered in this section.
Once a transfer switch is properly installed and wired, it should be
mechanically and electrically checked for proper installation and
operation. The procedures for these initial mechanical and electri-
cal checks are outlined in Section 5 of this manual.
4.2 Mounting Location
Choose a location that offers a flat, rigid mounting surface capa-
ble of supporting the weight of the enclosed ATS equipment (see
Figure 6). Protect the transfer switch at all times against exces-
sive moisture, dust, dirt, lint, and corrosive vapors.
