If you want to adapt this kind of transfer switch for single-phase loads, proceed as follows: 1. Discard the three-phase power monitor (PM) found inside the enclosure. You will not use it with a single-phase system. 2. Locate the eight-pin octal relay socket in the lower left corner of the transfer switch enclosure. 3. Move Wire N1A from Terminal 8 to Terminal 1 by cutting the lug off of N1A , stripping wire 5/16" from end, and inserting the wire under screw of Terminal 1. NOTE: Moving N1A from Terminal 8 to Terminal 1 takes the three-phase voltage monitor out of the sensing circuit. Now, the control circuit board in the control module assembly (CMA) senses utility voltage. 4. Now, connect the control wires as follows: • Connect Utility Supply to lugs N1 and N2. • Connect the Customer Load lugs T1 and T2. • Connect the Standby Supply to lugs E1 and E2. 1.15 CONTROL BOARD CONFIGURATION The control board for the 6 kW, 8 kW and 10 kw has four dip switches (see Figure 1.12), which may be set up differently during installation. 1. Dip switch 1: When in the ON position, the board requires 20 Vac from the step down transformer to the control board to determine if utility is present. This switch is factory preset and should not need to be changed. This switch should be set in the OFF position. 2. Dip switch 2: When in the ON position, it will disable the automatic starting of these units. This should be set when utility is not present at the installation location. This is the only switch that may need to be set to the ON position for these models. 3. Dip switch 3: It will allow for 50 Hertz operation and is not applicable to these models. This switch is factory preset and should not need to be changed. This switch should be set in the OFF position. 4. Dip switch 4: It has no function at this time. Figure 1.12 – Control Board Configuration 1.16 GROUNDING THE GENERATOR Generally, connecting a No. 12 AWG stranded copper wire to the grounding lug (Figure 1.13) and to an earthdriven copper or brass grounding rod (electrode) will adequately ground the generator. However, local codes may vary widely. Consult with a local electrician for grounding requirements in your area. Figure 1.13 – Grounding the Generator Section 1 — Installation Guardian Air-cooled Generators Section 1 — Installation Guardian Air-cooled Generators 1.17 THE BATTERY Servicing of the battery is to be performed or supervised by personnel knowledgeable of batteries and the required precautions. Keep unauthorized personnel away from batteries. When replacing the battery, use the following type of battery: Group 26/26R 12-volt battery with a rating of 350 cold-cranking amps at -17.8. C (0. F) minimum. When using a maintenance-free battery, it is not necessary to check the specific gravity or electrolyte level. Have these procedures performed at the intervals specified in the Owner’s Manual “Service Schedule.” A negative ground system is used. Battery connections are shown on the wiring diagrams. Make sure the battery is correctly connected and terminals are tight. Observe battery polarity when connecting the battery to the generator set. NOTE: Damage will result if the battery connections are made in reverse. Your generator is equipped with a battery trickle charger that is active when your unit is set up for automatic operation. The trickle charger is designed to help extend the life of your battery by maintaining the battery when the unit is not running. Do not dispose of the battery in a fire. The battery is capable of exploding. A battery presents a risk of electrical shock and high short circuit current. The following precautions are to be observed when working on batteries: • Remove watches, rings or other metal objects; • Use tools with insulated handles; • Wear rubber gloves and boots; • Do not lay tools or metal parts on top of the battery; and • Disconnect charging source prior to connecting or disconnecting battery terminals. Do not open or mutilate the battery. Released electrolyte has been known to be harmful to the skin and eyes, and to be toxic. The electrolyte is a dilute sulfuric acid that is harmful to the skin and eyes. It is electrically conductive and corrosive. The following procedures are to be observed: • Wear full eye protection and protective clothing; • Where electrolyte contacts the skin, wash it off immediately with water; • Where electrolyte contacts the eyes, flush thoroughly and immediately with water and seek medical attention; and • Spilled electrolyte is to be washed down with an acid neutralizing agent. A common practice is to use a solution of 1 pound (500 grams) bicarbonate of soda to 1 gallon (4 liters) or water. The bicarbonate of soda solution is to be added until the evidence of reaction (foaming) has ceased. The resulting liquid is to be flushed with water and the area dried. Lead-acid batteries present a risk of fire because they generate hydrogen gas. The following procedures are to be followed: • DO NOT SMOKE w...
