QUIETSOURCE™ 40kW Liquid-cooled Generators

Setting switch two to OFF allows the control PCB to perform the ATS control functions.

Control system interconnections consist of N1 and N2, and leads 23 and 194. Control system intercon- nection leads must be run in a conduit that is sepa- rate 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

SIZE

 

 

460 feet (140m)

No. 18 AWG.

 

 

461 to 730 feet (223m)

No. 16 AWG.

 

 

731 to 1,160 feet (354m)

No. 14 AWG.

No. 12 AWG.

 

 

 

 

 

‹2.9.2 GTS-TYPE ENGINEERED TRANSFER SWITCH

If the generator is to be installed with an engineered transfer switch, such as a 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.)

2.10BATTERY 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 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.

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.

‹2.10.1 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 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.

For recommended batteries, see Section 4.6.4. All batteries must be at 100 percent state-of-charge before they are installed on the generator.
