2.10 BATTERY INSTALLATION
DANGER
Standby generators installed with automatic
! transfer switches will crank and start automati- cally when NORMAL (UTILITY) source voltage is removed or is below an acceptable preset level. To prevent such automatic
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 min- imum capacity, or Group 27F, 12V negative ground 600 CCA/90 AH minimum capacity. All batteries must be at 100 percent
When using
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, serv- iced, 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) equip- ment.
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
2.11.2 TRANSFER SWITCH
If this generator is used to supply power to any elec- trical system normally powered by an electric utility, the National Electrical Code requires that a transfer switch be installed. The transfer switch prevents elec- trical backfeed between two different electrical sys- tems (for additional information, see the applicable transfer switch manual for this unit). The transfer switch, as well as the generator and other standby components, must be properly located and mounted in strict compliance with applicable codes, standards and regulations.
2.11.3 FUEL SYSTEM
Make sure the fuel supply system to the generator (a) delivers the correct fuel at the correct pressure and
(b)is properly purged and leak tested according to code. No fuel leakage is permitted. See “Specifications” (Section 1.10) for more information.
