Control system interconnection leads must be run in a conduit that is separate from the AC power lead. Recommended wire gauge sizes for this wiring depends on the length of the wire, as recommended below: MAXIMUM WIRE LENGTH RECOMMENDED WIRE SIZE 460 feet (140m) No. 18 AWG. 461 to 730 feet (223m) No. 16 AWG. 731 to 1,160 feet (354m) No. 14 AWG. 1,161 to 1,850 feet (565m) No. 12 AWG. • 2.9.2 GTS-TYPE ATS If the generator is to be installed with an automatic transfer switch, such as an engineered Generac GTS- type switch, it is necessary to connect the two-wire start control system. Connect the two-wire start signal from the automatic transfer switch to the automatic start connection, which is located in the middle, on the bottom, inside the control panel. Match wires 178 and 183 in the transfer switch to 178 and 183 on the terminal strip in the control panel. The conductors for the two-wire start circuit must be in their own conduit. (See Section 3.1 for further explanation.) 10 Generac® Power Systems, Inc. Section 2 — Installation Guardian Liquid-cooled 27 kW and 30 kW Generators 2.10 BATTERY INSTALLATION DANGER ! ! ! Standby generators installed with automatic transfer switches will crank and start automatically when NORMAL (UTILITY) source voltage is removed or is below an acceptable preset level. To prevent such automatic start-up and possible injury to personnel, do not connect battery cables until certain that normal source voltage at the transfer switch is correct and the system is ready to be placed into operation. Storage batteries give off explosive hydrogen gas. This gas can form an explosive mixture around the battery for several hours after charging. The slightest spark can ignite the gas and cause an explosion. Such an explosion can shatter the battery and cause blindness or other injury. Any area that houses a storage battery must be properly ventilated. Do not allow smoking, open flame, sparks or any spark producing tools or equipment near the battery. Battery electrolyte fluid is an extremely caustic sulfuric acid solution that can cause severe burns. Do not permit fluid to contact eyes, skin, clothing, painted surfaces, etc. Wear protective goggles, protective clothing and gloves when handling a battery. If fluid is spilled, flush the affected area immediately with clear water. Spilled electrolyte is to be washed down with an acid neutralizing agent. A common practice is to use a solution of one pound (500 grams) bicarbonate of soda to one gallon (4 liters) of 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. ! Do not dispose of the battery in a fire. The battery is capable of exploding. Do not open or mutilate the battery. Released electrolyte can be toxic and harmful to the skin and eyes. The battery represents a risk of high short circuit current. When working on the battery, always remove watches, rings or other metal objects, and only use tools that have insulated handles. When replacing batteries, use the same number and type of battery. The recommended batteries are Group 26, 12V negative ground 525 CCA/75 AH minimum capacity, or Group 27F, 12V negative ground 600 CCA/90 AH minimum capacity. All batteries must be at 100 percent state-of-charge before they are installed on the generator. When using maintenance-free batteries, it is not necessary to check the specific gravity or electrolyte level. Have these procedures performed at the intervals specified in Section 4, “Maintenance.” A negative ground system is used. Battery connections are shown on the wiring diagrams. Make sure all batteries are correctly connected and terminals are tight. Observe battery polarity when connecting batteries to the generator set. NOTE: Damage will result if the battery connections are made in reverse. 2.11 PREPARATION BEFORE START-UP The instructions in this section assume that the standby generator has been properly installed, serviced, tested, adjusted and otherwise prepared for use by a competent, qualified installation contractor. Be sure to read the “Safety Rules” on Pages 2 and 3, as well as all other safety information in this manual, before attempting to operate this (and related) equipment. • 2.11.1 PRIOR TO INITIAL START-UP ! Prior to initially starting the generator, it must be properly prepared for use. Any attempt to crank or start the engine before it has been properly serviced with the recommended types and quantities of engine fluids (oil, coolant, fuel, etc.) may result in an engine failure. Before starting the generator for the first time, the installer must complete the following procedures. For follow-up maintenance information and/or service intervals, please refer to Section 4, “Maintenance.” • 2.11.2 TRANSFER SWITCH If this generator is used to supply power to any electrical system normally powered by an electric utility, the National Electrical Code requ...
