Note: For FC, FCTB controller connections refer to their installation manuals 255294, 255326.
DANGER
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.
The power and control circuitry of a typical Model 2 installation is shown in figure 3-4. The schematic
diagram of the Model RC2W Motor Starter is also shown in the figure.
The RC2W Motor Starter is provided with various size knockout holes. Some of the knockouts can
accommodate 1/2" conduit fittings, others can accept 3/ 4" conduit fittings, and still others can accommodate 1"
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.
Figure 3-4. RC2W Electrical Connection
To connect the motor starter and siren to the power source and control circuitry, proceed as follows (see
figure 3-4):
1. Install conduit between the RC2W and the electrical leads on the side of the siren motor.
2. Install conduit between the RC2W and the disconnect switch.
