Figure 1-1 shows a typical single-line diagram. Figure 1-2 shows a typical transfer switch.
1.2 Overcurrent Protection Model KEP service entrance rated transfer switches have integral overcurrent protection supplied on the utility source as standard. Optional integral overcurrent protection may also be selected on the generator source. An upstream overcurrent protection device is required on the generator source if the integral overcurrent protection option is not specified on the generator side of the ATS.

Section 2 Installation 2.1 Introduction 2.2.2 Lifting WARNING Kohlerr transfer switches are shipped factory-wired, factory-tested, and ready for installation. Have the equipment installed only by trained and qualified personnel, and verify that the installation complies with applicable codes and standards. Switch installation includes the following steps: Unbalanced weight. Improper lifting can cause severe injury or death and equipment damage. D Unpack and inspect the transfer switch upon receipt.
2.2.3 Storage 2.2.4 Store the transfer switch in its protective packing until final installation. Protect the transfer switch at all times from moisture, construction grit, and metal chips. Avoid storage in low-temperature and high-humidity areas where moisture could condense on the unit. See Figure 2-2 for acceptable storage temperatures.
2.3 Multi-Tap Voltage Capability The transfer switch voltage is factory-set. Check the nameplate and confirm that the transfer switch has been configured for the correct system voltage prior to installation. Note: Verify that the transfer switch voltage matches the system voltage. The transfer switch has multi-tap voltage capability at the voltage transformers. See Figure 2-3 for a typical transformer assembly. Figure 2-4 shows typical connections.
2.4 Set Overcurrent Protection For models with integral overcurrent protection, the overcurrent protection must be set prior to operation. The equipment is shipped from the factory with a long-time current setting of 100% (of the equipment rating) and maximum short-time/ instantaneous current and time delay settings. Note: Do not energize this equipment until device settings have been verified to ensure proper system protection and coordination.
2.6 Seismic Certification Automatic transfer switches with seismic certification must be installed according to the instructions in this section. Also refer to ADV-7456, the Certificate of Compliance provided with the ATS, and the installation (ADV) drawings for the transfer switch. Abbreviations: ACI: American Concrete Institute IBC: International Building Coder SDS: Design spectral response acceleration at short period, as determined in Section 1615.1.

2.8 Controller Connections The controller is mounted in a plastic housing on the inside of the transfer switch enclosure door. DANGER Figure 2-8 shows the locations of the connectors on the controller. It is not necessary to open the cover to access the Ethernet, Modbusr, and input/output connectors. Opening the cover. If necessary, open the plastic housing by pushing up on the latch on the bottom of the cover and swinging the cover up and out. The cover is hinged at the top.
2.8.1 Controller Input and Output Connections 2.8.2 The controller provides connections for two programmable inputs and two programmable outputs. See Figure 2-8 for the connector location and Figure 2-9 for the I/O connection specifications. Each input has a signal and a return connection. The outputs are C form contacts with ratings of 500 mA @ 120 VAC. See Figure 2-10 for connections. Use #12--24 AWG wire and tighten the connections to 0.5 Nm (4.4 in. lbs.).

4.3 Accessory Modules (Option Boards) 4.3.1 Accessory Module Mounting Mount the accessory modules on the module mounting plate. Starting at the end of the module mounting assembly nearest the cable connection, install any I/O modules first, then install the alarm board, if used. The external battery module, if used, must be the last module. See Figure 4-9. The alarm board has a fixed Modbus address = 5. DANGER Hazardous voltage. Will cause severe injury or death.
4.3.2 Input/Output (I/O) Modules 1 2 Two types of input/output modules are available. The standard I/O Module has two inputs and six outputs. The high-power I/O module has two inputs and three outputs. See Figure 4-10 through Figure 4-13 for I/O module illustrations and specifications. 3 1 2 3 4 1. 2. 3. 4. Input LEDs 1 and 2 Input connector (see Figure 4-14) Output connector Output LEDs 3--5 for outputs 1, 2, and 3 Figure 4-12 4 1. 2. 3. 4.
Use 14-24 AWG cable to connect to inputs and outputs. See Figure 4-14. 4.3.3 LEDs on the module circuit board light to indicate that each input or output is active. The external battery supply module kit allows connection to the generator set engine start battery(ies) or other batteries to provide 12 VDC power to the ATS controller. The EBSM is also referred to as the battery option board (BOB). Note: Each I/O module must have a unique address.
The EBSM/BOB produces 2 amps at 12 VDC with 9--36 VDC input. The EBSM/BOB input is reverse-polarity protected. The EBSM/BOB outputs a low battery voltage signal when the external battery voltage falls below 11 VDC for a 12-volt system or 22 VDC for a 24-volt system. A module mounting kit is required for installation of the external battery supply module. See Section 4.3.1.
Alarm Board DIP Switches Alarm Operation, Chicago Alarm Mode There are four DIP switches on the alarm module board. Some of the switches are not used. See Figure 4-19. To enable the preferred source selection, set DIP switch 1 to ON. If the supervised transfer switch is installed on the ATS, set DIP switch 2 to ON. Chicago Alarm mode requires the horn to sound and a lamp or LED to light when the switch is in the emergency (non-preferred) position.
4.4 Heater DANGER 1 Hazardous voltage. Will cause severe injury or death. Disconnect all power sources before opening the enclosure. Servicing the transfer switch. Hazardous voltage can cause severe injury or death. Deenergize all power sources before servicing. Turn off the main circuit breakers of all transfer switch power sources and disable all generator sets as follows: (1) Press the generator set off/reset button to shut down the generator set. (2) Disconnect power to all battery chargers.

7.2 Changing the Service Disconnect Position In some applications, it may be necessary to change the service disconnect position on the transfer switch. Example 1: If you update the controller firmware or replace the controller on a unit that is equipped with an original transformer assembly, GM69797-KA1 or GM69797-KA2, you will need to change the service disconnect position setting on the controller back to Emergency.
7.2.1 Procedure to Change the Service Disconnect Position Setting on the Controller 1 1. Use a USB cable to connect your laptop PC to the MPAC controller. See Figure 7-3. 2. Start SiteTecht and wait for it to connect to the MPAC controller. 3. Click on Set Mpac Password and enter the distributor password. Obtain the password from the Kohler Power Systems Generator Service Department. 4. Find the Service Disconnect Position setting in the ATS Connection Configuration group. See Figure 7-4. GM85888 1.
7.2.2 Procedure to Disconnect the Engine Start Bypass Circuit Transfer switches using the new transformer assemblies include an engine start bypass circuit that prevents the ATS from sending an engine start signal to the generator when it is placed in the Service Disconnect position. If it is necessary to configure the ATS to operate in the Service Disconnect to Emergency position, this bypass circuit must be disconnected from the controller’s input connection.
6. Use cable ties to secure the leads out of the way. 7. Reconnect power to the control circuit. Follow the instructions in Section 6.5. 8. Use Kohlerr SiteTecht software to change the service disconnect position setting to Emergency. See the procedure in Section 7.2.1. 7.2.

Procedure for ICCB Models 1. At the generator (emergency) circuit breaker inside the transfer switch, find lead G-22, which is connected to terminal 22 on the circuit breaker auxiliary contact terminal block. See Figure 7-8. Disconnect lead G-22 and reconnect it to terminal 24. 2. At the utility (normal) circuit breaker, disconnect leads G-21 and U-21 from the circuit breaker auxiliary contact terminal block. Crimp leads G-21 and U-21 together. DETAIL A 1 1 TO P3 2 1.
7.2.4 Final Steps 1. On the enclosure door, change the service disconnect switch decal to show that the ATS now uses the Service Disconnect to Emergency position. Use a permanent marker or apply a new label over the existing decal that says: Service Disconnect transfers to EMERGENCY source and starts the generator set. 2. Return the generator set to service and place in AUTO. 3. Test the system operation.
