Generac 04675-3 Benutzerhandbuch

The following procedures 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, immediately

flush thoroughly 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 1 pound (500 grams) bicarbonate

of soda to 1 gallon (4 liters) or water. The bicar-

bonate 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 procedures are to be followed:

• DO NOT SMOKE when near the battery;

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

• Discharge static electricity from body before touch-

ing the battery by first touching a grounded metal

surface.

Be sure the AUTO/OFF/MANUAL switch is set to

the OFF position before connecting the battery

cables. If the switch is set to AUTO or MANUAL,

the generator can crank and start as soon as the

battery cables are connected.

Be sure the utility power supply is turned off, or

sparking may occur at the battery posts as the

cables are attached and cause an explosion.

2.1 BEFORE INITIAL START-UP

Before starting, complete the following:
1. Set the generator’s main circuit breaker to its

OFF (or open) position.

2. Set the generator's AUTO/OFF/MANUAL switch to

the OFF position.

3. Turn OFF the utility power supply to the transfer

switch using the means provided (such as the

utility main line circuit breaker).

4. Check the engine crankcase oil level and, if neces-

sary, fill to the dipstick FULL mark with the rec-

ommended oil. Do not fill above the FULL mark.

5. Check the fuel supply. Gaseous fuel lines must

have been properly purged and leak tested in

accordance with applicable fuel-gas codes. All

fuel shutoff valves in the fuel supply lines must

be open.

Never operate the engine with the oil level

below the “Add” mark on the dipstick. Doing

this could damage the engine.

2.2 CHECK TRANSFER SWITCH

OPERATION

Refer to Section 3.5 of the owner’s manual for manu-

al operation procedures.

DANGER

Do not attempt manual transfer switch opera-

tion 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.

2.3 ELECTRICAL CHECKS

Complete electrical checks as follows:
1. Turn on the utility power supply to the transfer

switch using the means provided (such as a utility

main line circuit breaker).

DANGER

The transfer switch is now electrically “hot.”

Contact with “hot” parts will result in extremely

hazardous and possibly fatal electrical shock.

Proceed with caution.

2. Use an accurate AC voltmeter to check utility

power source voltage across terminals N1 and

N2. Nominal line-to-line voltage should be 240

volts AC.

3. Check utility power source voltage across termi-

nals N1 and the transfer switch neutral lug; then

across terminal N2 and neutral. Nominal line-to-

neutral voltage should be 120 volts AC.

4. When certain that utility supply voltage is compat-

ible with transfer switch and load circuit ratings,

turn OFF the utility power supply to the transfer

switch.

5. Set the generator's main circuit breaker to its

OFF (or open) position. Initial tests will be con-

ducted at no-load condition.

6. On the generator panel, set the AUTO/OFF/

MANUAL switch to MANUAL. The engine should

crank and start.

7. Let the engine warm up for about five minutes to

allow internal temperatures to stabilize. Then, set

the generator’s main circuit breaker to its ON (or

closed) position.

DANGER

Proceed with caution! Generator power voltage

is now supplied to the transfer switch. Contact

with live transfer switch parts will result in dan-

gerous and possibly fatal electrical shock.
