SAFETY INFORMA TION

This engine generator set has been designed and manufactured to allow safe, reliable performance. Poor maintenance, improper or careless use can result in potential deadly hazards; from electrical shock, exhaust gas asphyxiation, or fire. Please read all safety instructions carefully before installation or use. Keep these instructions handy for future reference. Take special note and follow all warnings on the unit labels and in the manuals.

b. Keep fuel containers out of reach of children. c. Do not smoke or use open flame near the

generator set or fuel tank.

d. Keep a fire extinguisher nearby and know its

proper use. Fire extinguishers rated ABC by NFPA are appropriate.

e. Store fuel only in an approved container, and only

in a well-ventilated area.

f. Follow local codes for closeness to combustible

material.

ANSI SAFETY DEFINITIONS

************************************************************

DANGER:

DANGER indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. This signal word is to be limited to the most extreme situations.

*********************************************************** ************************************************************

WARNING:

WARNING indicates a potentially hazardous situation

which, if not avoided, could result in death or serious injury.

***********************************************************

CAUTION:

CAUTION indicates a potentially hazardous situation

which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices.

************************************************************

NOTE:

CAUTION is also used on the unit labels and in this

manual to indicate a situation that could result in serious damage or destruction of the equipment and possible personal injury.

1. ELECTRIC SHOCK - The output voltage present in this equipment can cause a fatal electric shock. This equipment must be operated by a responsible person.

3. DEADL Y EXHAUST GAS - Exhaust fumes from any gasoline engine contain carbon monoxide, an invisible, odorless and deadly gas that must be mixed with fresh air.

a. Operate only in well ventilated areas. b. Never operate indoors. c. Never operate the unit in such a way as to allow

exhaust gases to seep back into closed rooms (i.e. through windows, walls or floors).

4. NOISE HAZARD - Excessive noise is not only tiring, but continual exposure can lead to loss of hearing.

a. Use hearing protection equipment when working

around this equipment for long periods of time.

b. Keep your neighbors in mind when permanently

installing this equipment.

5. CLEANLINESS - Keep the generator and surrounding area clean.

a. Remove all grease, ice, snow or materials that

create slippery conditions around the unit.

b. Remove any rags or other material that could

create potential fire hazards.

c. Carefully clean up any gas or oil spills before

starting the unit.

d. Never allow leaves or other flammable material

to build up around the engine intake or exhaust area.

6. SERVICING EQUIPMENT - All service, including the installation or replacement of service parts, should be performed only by a qualified technician.

a. Do not allow anyone to operate the generator

without proper instruction. b. Guard against electric shock. c. Avoid contact with live terminals or receptacles. d. Use extreme care if operating this unit in rain or

snow. e. Use only three-prong grounded receptacles and

extension cords. f. Be sure the unit is properly grounded to an

external ground rod driven into the earth.

2. FIRE HAZARD - Natural gas and L.P. present a hazard of possible explosion and/or fire.

a. Do not refuel when the engine is running or hot.

Allow the engine to cool at least two minutes before refueling.

PAGE 1

a. Use only factory approved repair parts. b. Do not work on this equipment when fatigued. c. Never remove the protective guards, cover, or

receptacle panels while the engine is running.

d. Use extreme caution when working on electrical

components. High output voltages from this equipment can cause serious injury or death.

e. Always avoid hot mufflers, exhaust manifolds,

an d engine parts. They all can cause severe burns instantly.

f. Installing a generator set is not a “do-it-yourself”

project. Consult a qualified, licensed electrician or contractor. The installation must comply with all national, state, and local codes.

TESTING POLICY:

UNPACKING INSTRUCTIONS

Before any Automatic Transfer Switch (A.T.S.) is shipped from the factory, it is fully checked for performance.

Rated capability of the Automatic Transfer Switch is based on engineering tests of typical units, and is subject to, and limited by, the temperature, and other conditions specified by the manufacturer.

DESCRIPTION

These wall mounted Automatic Transfer Switch (A.T.S.) are designed for inside installation. The A.T.S. consists of a line side contactor and a generator side contactor. The contactors are both electrically and mechanically interlocked.

An automatic taper battery trickle charger (40 MA max.) and a seven day electronic exerciser clock are installed in the A.T.S. as standard equipment. The battery trickle charger is not designed to recharge a low battery, but is designed to keep a fully charged battery in peak operating condition. The exerciser clock is electronically programmable, which allows you to set multiply exercise periods during the week. These exercise periods can be from 1 second long to hours long depending on how long you want it operate.

The A.T.S. also contains the power failure sensing circuitry necessary to send a start/stop signal to the engine generator set. These switches are designed to close to ground (Battery Negative) upon failure of normal power. If the engine control you are using needs a positive signal or some other type of signal to initiate the start sequence you will have to install a pilot relay in the start circuit. (Consult the factory for details.)

During normal operation the A.T.S. will supply normal line power to the loads connected to the load terminals in the switch. Upon an interruption of normal electrical service the A.T.S. will close the start/stop relay sending a start signal to the engine-generator set. Once the enginegenerator is producing electricity, the Automatic Transfer Switch will transfer the connected loads to the enginegenerator set. Upon restoration of normal electrical service the A.T.S. will sense the return of the normal commercial power and retransfer the connected loads back to the normal power source. At the same time the start/stop relay will open removing the start signal being sent to the engine control, allowing the engine-generator set to shut down.

** NOTICE **

When unpacking the Automatic Transfer Switch, be sure to inspect it carefully for freight loss or damage. If loss or damage is noted at the time of delivery, require that the person making the delivery make note of the loss or damage on the freight bill, or affix his signature under the consignor’s memo of the loss or damage. Contact the carrier for claim procedures.

When loss or damage is noted after delivery, segregate the damaged material, and contact the carrier for claim procedures. Be sure to retain the packaging material for carrier inspection.

“Concealed Damage” is understood to mean damage to the contents of a package which is not evident at the time of delivery by the carrier, but which is discovered later. The carrier or carriers are responsible for merchandise lost or damaged in transit. The title to goods rests with the consignee when generators are shipped F.O.B. factory, and only the consignee can legally file a claim.

UNPACKING:

1. Carefully remove the carton.

2. After inspecting the Automatic Transfer Switch for external physical damage. Carefully inspect the contactors, contactor interlocks and the contactor mountings, to insure no damage has occurred to the contractors during shipment and handling.

3. Check inside the carton for the owner’s manual, wiring diagram and parts list.

INSTALLATION

General Information

************* ***** WARNING **** *************

Before proceeding with the installation, be sure the operation selector switch is in the STOP position.

Before beginning the installation process recheck the rating of the transfer switch to be certain it can handle the intended load and is compatible with the entrance voltage, phase and current ratings. Plans for installation should be prepared with proper attention to mechanical and electrical engineering detail to assure a satisfactory installation. The information in this manual is offered only as a guide to finalizing your installation plans.
