Section 2 — Installation

Liquid-cooled 15, 20 and 25 kW Generators

Transfer Switch terminals N1 and N2 (also called Utility 1 and Utility 2) are the input utility AC power connections to the Transfer Switch. Transfer Switch terminals T1 and T2 (also called Load 1 and Load 2) are the transfer switch AC output power terminals that go to the load circuit distribution panel. Transfer Switch terminals E1 and E2 are the AC power termi- nals that come from the generator's main alternator.

When in GTS mode, the control board will respond as follows based on the generator AUTO/OFF/MANU- AL switch position.

OFF — The generator will not start and run in this position

MANUAL — The generator control board will start and run the generator whenever the switch is in the manual position.

AUTO — The generator control board will monitor the 2-Wire start circuit (terminals 178 and 183 in the generator control panel). When a 2-Wire start signal is issued by the W type engineered transfer switch, via a relay contact closure that connects wire 178 to wire 183, the generator control board will immedi- ately start and run the generator. When the 2-Wire start signal is removed the control board will imme- diately stop the generator.

2.11BATTERY 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 possible 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 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 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.

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 cir- cuit current. When working on the battery, always remove watches, rings or other metal objects, and only use tools that have insulated handles.

‹2.11.1 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 med- ical 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 fol- lowing procedure 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.
