NOTE:
For the FC and FCTB controller connections see their installation manuals:
255294 and 255326.
Electrocution or severe personal injury can occur when making electrical
connections, drilling holes, or lifting equipment. Therefore, installation should
be performed by experienced electricians in accordance with national and
local electrical codes and ordinances, including any state or local noise control
ordinances
The power and control circuitry of a typical Model 2 installation is shown in Figures 5
and 6. The schematic diagram of the Model RC2W Motor Starter is also shown in the
figures.
The RC2W Motor Starter is provided with various size knockout holes. Some of the
knockouts can accommodate 1/2-inch conduit fittings, others can accept 3/4-inch conduit
fittings, and still others can accommodate 1-inch conduit fittings. These various sized
knockout holes are provided because electrical wiring requirements are frequently
unpredictable. The diameter of the conduit required for the installation depends on the
AWG size of the wiring used, the type of insulation on the wiring, and local electrical
codes. Therefore, be sure that the size of the conduit selected meets the requirements of
the installation.
