Section 1

Safety

1.1 — Introduction

Read this manual thoroughly

.

If any portion is not understood, contact the nearest Authorized Generac Service

Dealer for clarification. The manufacturer also requires having an Authorized Service Dealer oversee the installation of any standby generator set. Trained/qualified service technicians familiar with the control systems and available options have full access to drawings, publications, and other information required for a successful installation.

1.2 — Safety Rules

Throughout this publication, and on tags and decals affixed to the generator, DANGER, WARNING, CAUTION, and

NOTE boxes are used to alert personnel to special instructions about a particular operation that may be hazardous if performed incorrectly or carelessly. Observe them carefully. They indicate:

Indicates a hazardous situation or action that, if not avoided, will result in death or serious injury.

Indicates a hazardous situation or action that, if not avoided, could result in death or serious injury.

Indicates a hazardous situation or action that, if not avoided, could result in minor or moderate injury.

NOTE: Notes provide additional information important to a procedure or component.

These safety warnings cannot eliminate the hazards they indicate. Observing safety precautions and strict compliance with the special instructions while performing the action or service are essential to preventing accidents.

Four commonly used safety symbols accompany DANGER, WARNING, and CAUTION boxes and the type of information each indicates:

Safety

The manufacturer cannot anticipate every possible circumstance that might involve a hazard. The warnings in this manual, and on tags and decals affixed to the unit, are not all-inclusive. If using a procedure, work method, or operating technique the manufacturer does not specifically recommend, ensure that it is safe for others. Also make sure the procedure, work method, or operating technique used does not render the generator unsafe.

Despite the safe design of this generator, operating this equipment imprudently, neglecting its maintenance, or being careless can cause possible injury or death. Permit only responsible and capable persons to install, operate, and maintain this equipment.

Parts of the generator are rotating and/or hot during operation. Exercise care near running generators.

If this generator is used to power electrical load circuits normally powered by a utility power source, install a transfer switch. The transfer switch must effectively isolate the electrical system from the utility distribution system when the generator is operating. Failure to isolate an electrical system by such means will result in damage to the generator and also may result in injury or death to utility power workers due to backfeed of electrical energy.

+

Generators produce potentially lethal voltages. Ensure all steps are taken to make the generator safe before operation or service.

1.3 — General Hazards

For safety reasons, the manufacturer recommends that this equipment be installed, serviced, and repaired by an

Authorized Service Dealer or other competent, qualified electrician or installation technician who is familiar with all applicable codes, standards, and regulations.

Ensure that the generator is installed, operated, and serviced in accordance with the manufacturer’s instructions and recommendations. Following installation, do nothing that might render the unit unsafe or in noncompliance.

The engine exhaust fumes contain carbon monoxide, which can be DEADLY. If breathed in sufficient concentrations, carbon monoxide can cause unconsciousness or even death. For this reason, adequate ventilation must be provided. Exhaust gases must be piped safely away from any building or enclosure that houses the generator to an area where people, animals, etc. will not be harmed.

Keep hands, feet, clothing, etc. away from drive belts, fans, and other moving or hot parts. Never remove any drive belt or fan guard while the unit is operating. Ensure that all guards, covers, and protective devices removed during maintenance or service are reinstalled.

Adequate, unobstructed flow of cooling and ventilating air is critical to prevent buildup of explosive gases and to ensure correct generator operation. Do not alter the installation or permit even partial blockage of ventilation provisions, as this can affect safe operation of the generator.

Keep the area around the generator clean and uncluttered. Remove any materials that could become hazardous.

When working on this equipment, remain alert at all times. Never work on the equipment when physically or mentally fatigued.

Inspect the generator regularly, and promptly repair or replace any worn or damaged components using only factory approved parts and procedures.

Before performing any maintenance on the generator, always disconnect the battery cables to prevent accidental startup. Disconnect the cable from the battery post indicated by a NEGATIVE, NEG, or (–) first, then remove the

POSITIVE, POS, or (+) cable. When reconnecting the cables, connect the POSITIVE cable first, the NEGATIVE cable last.

Never use the generator or any of its parts as a step. Stepping on the unit can stress and break parts, and may result in exhaust, fuel, oil or coolant leaks.

Installation Guidelines for Stationary Diesel Generators

Safety

1.4 — Electrical Hazards

All generators produce dangerous electrical voltages and can cause fatal electrical shock. Utility power delivers extremely high and dangerous voltages to the transfer switch as well as the generator when it is in operation.

Avoid contact with bare wires, terminals and other connections. Ensure all covers, guards, and barriers are in place, and that they are properly secured and/or locked before operation. If work must be done around an operating unit, stand on an insulated, dry surface to reduce potential shock hazard.

Do not handle any kind of electrical device while standing in water, while barefoot, or while hands or feet are wet.

DANGEROUS ELECTRICAL SHOCK MAY RESULT.

If it is necessary to stand on metal or concrete while installing, operating, servicing, or repairing this equipment, lay down a dry wooden platform and cover with insulated mats before beginning.

Verify that the generator is properly grounded.

Wire gauge sizes of electrical wiring, cables, and cord sets must be adequate to handle the maximum electrical current (ampacity) to which it will be subjected.

Before installing or servicing equipment, verify that all power voltage supplies are positively turned off at their sources. Failure to do so can result in hazardous and possibly fatal electrical shock.

Connecting this unit to an electrical system normally supplied by an electric utility is by means of a transfer switch so as to isolate the generator electric system from the electric utility distribution system when the generator is operating. Failure to isolate the two electric system power sources from each other by such means will result in damage to the generator and may also result in injury or death to utility power workers due to backfeed of electrical energy.

Generators installed with an automatic transfer switch will crank and start automatically when NORMAL (UTIL-

ITY) source voltage is removed or is below an acceptable preset level. To prevent automatic startup and possible injury, disable the automatic start circuit (battery cables, etc.) before working on or around the unit. Place a “DO

NOT OPERATE” tag on the generator control panel and on the transfer switch.

In case of accident caused by electric shock, immediately shut down the source of electrical power. If this is not possible, attempt to free the victim from the live conductor. AVOID DIRECT CONTACT WITH THE VICTIM. Use a nonconducting implement, such as a dry rope or board, to free the victim from the live conductor. If the victim is unconscious, apply first aid and get immediate medical help.

Do not wear jewelry when working on this equipment. Jewelry can conduct electricity resulting in electric shock, or may get caught in moving parts resulting in injury.

1.5 — Fire Hazards

Keep a fire extinguisher near the generator at all times. Keep the extinguisher properly charged and be familiar with its use. Direct any questions to the local fire department.

NOTE: DO NOT use any carbon tetra-chloride type fire extinguishers. These fire extinguishers emit toxic fumes and the liquid can damage wiring insulation.

1.6 — Explosion Hazards

Properly ventilate the room or building housing the generator to prevent buildup of explosive gas.

Do not smoke around the generator. Immediately wipe up any fuel or oil spills. Ensure that no combustible materials are left in the generator compartment, or on or near the generator, as FIRE or EXPLOSION may result.

Keep the area surrounding the generator clean and free of debris.

All types of fuels are potentially FLAMMABLE and/or EXPLOSIVE and must be handled with care. Inspect the fuel system frequently and correct any leaks immediately. Be sure fuel supply lines are properly installed, purged, and leak tested before placing the generator set into service.

Diesel Fuel Systems

5.1 — General Information

Since diesel fuels are less volatile than gasoline or gaseous fuels, they are sometimes considered safer. Due to this perception, careless installation practices can occur, which may lead to serious problems with generator set performance and reliability.

Periodically inspect and test the system to ensure all components remain in good working order.

5.2 — Diesel Fuel Base Tank

Units provided are typically mounted on their own base/fuel tank. See Figure 5-1. These are plumbed at the factory.

The base tank is the main fuel tank and incorporates the following items:

Fill Line – some are equipped with overflow containment.

Vent Line – some applications require extending the vent line outside of an enclosure or to outside air along with adequate spill containment.

Fuel supply line to engine pump with in-line check valve.

Fuel return line from engine, sometimes supplied with a check valve.

Fuel level indication (electrical, mechanical or both).

Double wall construction with rupture basin and level indicator switch.

Emergency vent on main tank and rupture basin.

Remove six screws with flat washers to release stub up cover.

6.3 — Wiring Installation Safety

Review the safety rules at the beginning of this manual for specific dangers, cautions, and hazards associated with the installation of industrial products.

When installing the generator set and connecting wiring, keep the generator and system de-energized and disabled. It is common electrical safety practice to verify that wires are de-energized using appropriate safety gear and a meter before handling. Disable the generator by placing the AUTO/OFF/MANUAL switch in the OFF position, de-energize the battery charger, and disconnect the negative cable from the negative battery terminal. Also, make sure the 120/240,

120/208 auxiliary power circuit to the unit is de-energized.

6.4 — General Wiring Requirements

Consider the following general wiring requirements:

Load Wiring - Properly size and select wiring.

Control Wiring - Typically low DC voltage wiring (12-

24Vdc) that includes the 2-wire start and signal wiring.

Use multi-strand wire appropriately sized for the length of run. Do not exceed #12 AWG when connecting to the customer connection terminals.

Accessory Power Wiring - Provides power for optional user accessories (battery warmer and block heater). Size and select wiring using the appropriate tables in the NEC and per the connection requirements in the individual control panel wiring diagram.

A = Rear Panel

B = Stub Up Cover

Install rear panel. For best results, first engage right side of panel and then rotate left side inward toward enclosure. Alternately work left and right sides in until slots are aligned with screw holes on both sides. Install six screws with nylon washers and tighten until snug.

6.9 — Transfer Switch Location

The location of the transfer switch is important. Consider the following:

1.

Locate the transfer switch as close to the emergency load as practical to avoid interruptions of the emergency power system due to natural disasters or equipment failures.

2.

3.

Locate the transfer switch in a clean, dry, well ventilated location, away from excessive heat. When the ambient air is above 104° F (40° C), fuses and circuit breakers must be derated. Allow adequate working space around the transfer switch. Refer to the latest NEC, state and local AHJ requirements for details.

Install a circuit breaker (or fuses) in the line between the generator and the transfer switch. Generator sets are available with properly sized circuit breaker built into the generator control. The circuit breaker can be separately mounted. In the case of very large circuit breakers, a separate floor mounted circuit breaker is easier to wire up than a wall mounted breaker.

4.

5.

6.

Install power and control wires as per NEC requirements with flexible sections at the generator set. The flexible sections prevent vibration from damaging the conduit. All power conduits from the generator set must contain all three phases.

Conduit, wire, circuit protective device sizes, insulation etc. must conform to applicable local and national codes and regulations.

Be certain to seal around conduits that penetrate the walls of the generator set room to reduce the amount of noise that is transmitted to the surrounding areas of the building and maintain site fire code rating.

22 Installation Guidelines for Stationary Diesel Generators

Electrical System

6.10 — Battery

6.10.1— General Cautions

*

Stationary emergency generators installed with automatic transfer switches will crank and start automatically when NORMAL (UTILITY) source voltage is removed or is below an acceptable preset level. To prevent automatic startup and possible injury to personnel, do not connect battery cables until NOR-

MAL 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. 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.

+

+

*

*

When working on the battery, always remove watches, rings, or other metal objects, and only use tools that have insulated handles. Do not lay tools or metal parts on top of the battery.

Discharge static electricity from the body before touching the battery by first touching a grounded metal surface.

Wear full eye protection, protective clothing, and gloves when handling a 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. Where electrolyte contacts the skin, wash it off immediately with water. If contact is with eyes, flush thoroughly and immediately with water and seek medical attention.

NOTE: Immediately wash down spilled electrolyte with an acid neutralizing agent. Use a solution of 1 pound

(500 grams) bicarbonate of soda to 1 gallon (4 liters) of water. Add the bicarbonate of soda solution until evidence of reaction (foaming) has ceased. Flush the resulting liquid with water.

6.10.2— Battery Size

The ability to start the engine depends upon battery capacity, ambient temperatures and coolant and oil temperatures.

The engine/generator set Data Sheet lists minimum recommended battery capacity at various ambient temperatures.

The recommended battery capacities are listed under cold cranking amps (CCA) at 0 °F ( − 18 °C). Battery capacities decrease as ambient temperatures decrease, so it is important to specify batteries with the appropriate CCA rating at a temperature no higher than the minimum ambient temperature for the application.

6.10.3— Battery Replacement

For battery replacement, consult the unit specification sheet for battery size. Battery cables are factory connected at the generator connection points. Fill the battery with the proper electrolyte fluid if necessary and have the battery fully charged before installing.

6.11 — Operational Checks

NOTE:

The following procedures require special tools and skills. Contact a Generac Dealer or an authorized service provider to perform these tasks.

6.11.1— Self Test

Upon power up, the controller goes through a system self test which checks for the presence of utility voltage on the

DC circuits. This is done to prevent damage if the installer mistakenly connects AC utility power sense wires into the

DC terminal block. If utility voltage is detected, the controller displays a warning message and locks out the generator, thereby preventing damage to the controller. Remove power to the controller to clear this warning.

Utility voltage must be turned on and present at the N1 and N2 terminals inside the generator control panel for this test to be performed and pass.

Before starting, complete the following:

1.

2.

3.

4.

Verify that the generator is OFF. A red LED above OFF on the control panel keypad illuminates to confirm that the system is in the OFF mode.

Verify that the Main Circuit Breaker switch on the generator control panel is in the OFF (Open) position.

Turn off all circuit breakers/electrical loads that will be powered by the generator.

Check the engine crankcase oil level, coolant level, and fuel level, if necessary.

Installation Guidelines for Stationary Diesel Generators 25

Electrical System

During initial start up only, the generator may exceed the normal number of start attempts and experience an “over crank” fault. This is due to accumulated air in the fuel system during installation. Reset the control board and restart up to two more times, if necessary. If unit fails to start, contact the local dealer for assistance.

6.11.2— Check Manual Transfer Switch Operation

Refer to the “Manual Transfer Operation” section of the owner’s manual for procedures.

NOTE: Also use the appropriate transfer switch owner’s manual for manual and automatic system test.

+

Do not attempt manual transfer switch operation until all power voltage supplies to the transfer switch have been positively turned off. Failure to turn off all power voltage supplies will result in extremely hazardous and possibly fatal electrical shock.

6.11.3— Electrical Checks

3.

4.

Turn OFF all circuit breakers/electrical loads that will be powered by the generator.

Turn on the utility power supply to the transfer switch using the means provided (such as a utility main line circuit breaker).

+

The transfer switch is now electrically “hot.” Contact with “hot” parts will result in extremely hazardous and possibly fatal electrical shock.

5.

6.

7.

8.

9.

Use an accurate AC voltmeter to check utility power source voltage across transfer switch terminals N1, N2, and

N3 (if three phase). Normal line-to-line voltage should be equivalent to rated unit voltage.

10.

11.

12.

13.

Connect an accurate AC voltmeter and a frequency meter across transfer switch terminal lugs E1, E2, and E3 (if three phase).

Successively connect the AC voltmeter test leads across terminal lugs E1, E2, and E3 (if three phase) and neutral; then across E2 and neutral. Voltage reading in each case should match utility voltage reading. If system is three phase, verify that generator phase rotation matches utility phase rotation.

Move the Main Circuit Breaker switch on the generator control panel down to the OFF (Open) position.

Press OFF on the control panel keypad to shut the engine down.

+

Do not proceed unless certain that generator AC voltage and frequency are correct and within the stated limits.
