2 Introduction 2.1 Owner Manual This manual covers models produced under the Cummins® Power Generation (CPG) brand names. This manual provides information necessary for operation, installation, and service of RA Series transfer switches. This manual also includes parts information. This is an open transition transfer switch which does not include an integral automatic transfer switch (ATS) control. With an open transition switch, there is never a time when both sources are supplying power to the load.
PAGE 14
2. Introduction 2.2 3-2016 Transfer Switch Application Transfer switches are an essential part of a building's standby or emergency power system. The utility line (normal power), is backed up by a generator set (emergency power). The transfer switch switches the electrical load from one source to the other. The load is connected to the common of the ATS (Figure 5). Under normal conditions, the load is supplied with power from the utility (as illustrated).
PAGE 15
3-2016 2. Introduction 4. Transfers the load to the generator set 5. Senses the return of utility power 6. Sends utility available signal to generator set 7. Receives retransfer command from generator set control 8. Retransfers the load to the utility The transfer switch design is intended to signal when the utility voltage is not present and when it returns. The utility sense relay coil will energize or stay energized at voltages other than nominal.
PAGE 16
2. Introduction 3-2016 The nameplates for the RA Series transfer switches are located inside the cabinet in the following locations: • RA 100A/200A transfer switches: On the upper right side (see Figure 7 and Figure 9).

3-2016 2. Introduction • Engines-Gasoline or Engines-Diesel, • Recreational Vehicles-Equipment, or • Parts and Service If it is necessary to contact a distributor regarding the transfer switch, always give the complete Model and Serial number. This information is necessary to properly identify your unit among the many types manufactured. WARNING Removing the front door will expose the operator to hazardous voltage. Ensure that both sources are de-energized and locked out prior to removing the door.

3-2016 2. Introduction FIGURE 13. 2.6 RA 400A SERVICE ENTRANCE MODEL Installation Overview These installation recommendations apply to typical installations. Whenever possible, these recommendations also cover factory designed options or modifications. However, because of the many variables in any installation, it is not possible to provide specific recommendations for every situation. If there are any questions not answered by this manual, contact your nearest Cummins/Onan distributor for assistance.
PAGE 24
2. Introduction 2.6.1 3-2016 Application and Installation Installations must be carefully planned and correctly installed for proper operation. This involves two essential elements: application and installation. Application refers to the design of the complete standby power system that usually includes power distribution equipment, transfer switches, ventilation equipment, mounting pads, cooling systems, exhaust systems, and fuel systems.
PAGE 25
3 Installation 3.1 Installation - Mounting 3.1.1 Introduction Proper storage, installation, operation, and maintenance helps to increase the life of the transfer switch. Installation is to be done only by licensed certified electricians. WARNING AC power within the cabinet presents a shock hazard that can cause severe personal injury or death. Incorrect installation, service, or parts replacement can result in severe personal injury, death, and/or equipment damage.
PAGE 26
3. Installation 3-2016 Choose a vibration-free mounting surface that supports the weight of the switch. Avoid locations that are near flammable liquids or gases, or are hot, moist, or dusty. WARNING An electrical arc occurs during transfer that can ignite a flammable atmosphere, resulting in severe personal injury or death. The switch must not be located near batteries, fuel tanks, solvents, or other sources of flammable liquids or gases, or in areas sharing ventilation with such sources. 3.1.
