Generac 005031-2 Battery Installation, Pos2 OFF — ATS Application, ‹2.10.1 VENTED BATTERIES

Section 2 — Installation

•The control board WILL monitor all engine condi- tions and shut down on all the faults listed in this document.

Pos2 OFF — ATS Application

•The control board will perform all of the automatic features listed in this document.

•The two-wire start connections, wires 178-183, should NOT be connected.

NOTE:

If the generator is installed in conjunction with an engineered GTS type engineered transfer switch, refer to the applicable transfer switch manual for exact operating parameters and timing sequenc- es.

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 start-up and pos- sible injury to personnel, do not connect battery cables until certain that normal source voltage at the transfer switch is correct; the generator main line circuit breaker is switched to OFF; the AUTO/OFF/MANUAL switch on the control con- sole is switched to OFF; the 15A and 5A fuses have been removed from the control console; utility fed supply to battery charger (terminals N1 and N2) is removed; and the system is ready to be placed into operation. Ensure that the 5A and 15A fuses in the control panel are removed when connecting or disconnecting battery cables.

Storage batteries give off explosive hydrogen gas. This gas can form an explosive mixture around the battery for several hours after charg- ing. The slightest spark can ignite the gas and cause an explosion. Such an explosion can shat- ter the battery and cause blindness or other injury. Any area that houses a storage battery must be properly ventilated. Do not allow smok- ing, open flame, sparks or any spark producing tools or equipment near the battery.

Battery electrolyte fluid is an extremely corro- sive 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.

Liquid-cooled 25 kW Generators

Do not dispose of the battery in a fire. The bat- tery 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.

‹2.10.1 VENTED BATTERIES

The electrolyte is a dilute sulfuric acid that is harmful to the skin and eyes. It is electrically conductive and corrosive. The following proce- dures 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 thor- oughly 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 one pound (500 grams) bicarbon- ate 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.

Lead acid batteries present a risk of fire because they generate hydrogen gas. The following pro- cedure are to be followed:

•DO NOT SMOKE when near batteries,

•DO NOT cause flame or spark in battery area, and

•Discharge static electricity from body before touch- ing batteries by first touching a grounded metal surface.

Servicing of batteries is to be performed or super- vised by personnel knowledgeable of batteries and the required precautions. Keep unauthorized person- nel away from batteries.

The recommended battery is Group 26, 12VDC, 550 CCA/75 AH minimum. All batteries must be at 100 percent state-of-charge before they are installed on the generator.
