9 Avoid connecting the generator in parallel with any other generator.

1 Correct 2 Incorrect

Connection

WARNING Before the generator can be connected to a build- ings electrical system, a licensed electrician must install an isolation (transfer) switch in the build- ings main fuse box. The switch is the connection point for generator power and allows selection of generator or main line power to the building. This will prevent the generator from charging the main power line (backfeeding) when the main power supply has failed or has been turned off for line repair. Backfeeding can electrocute or injure line maintenance personnel. Also, generator and build- ing electrical system damage can occur when nor- mal operating power returns if unit is used without an isolation switch.

Extension cord notes Extension cords should be protected by a tough flexi- ble rubber sheath (IEC 245) or the equivalent to with- stand mechanical stresses.

Overload indicator light (red) The overload indicator light (red) comes on when an overload of a connected electrical device is detected, the inverter control unit overheats, or the AC output voltage rises. The electronic breaker will then activate, stopping power generation in order to protect the gen- erator and any connected electric devices. The AC pilot light (green) will go off and the overload indicator light (red) will stay on, but the engine will not stop running.

1 Overload indicator light (red)

When the overload indicator light (red) comes on and power generation stops, proceed as follows: 1. Turn off any connected electric devices and stop

the engine.

2. Reduce the total wattage of connected electric devices within the rated output.

3. Check for blockages in the cooling air inlet and around the control unit. If any blockages are found, remove them.

2 Cooling air inlet

4. After checking, restart the engine.

TIP 9 The generator AC output automatically resets

when the engine is stopped and then restarted. 9 The overload indicator light (red) may come on for

a few seconds at first when using electric devices that require a large starting current, such as a compressor or a submersible pump. However, this is not a malfunction.

9 For EF3000iSEB, the overload indicator light (red) may flash when using electric devices that require a large starting current. However, this is not a malfunction. (The flashing indicator is a result of the generator temporarily discharging more than its rated wattage.)

While the overload indicator light (red) is flashing, electric devices that require a large starting cur- rent cannot be started.

Battery charging

NOTICE

9 Do not connect a VRLA (Valve Regulated Lead Acid) battery. To charge a VRLA battery, a spe- cial (constant voltage) battery charger is required.

9 Do not use AC and DC power at the same time or the generator may be damaged.

TIP 9 The generator DC rated voltage is 12 V. 9 Start the engine first, and then connect the gener-

ator to the battery for charging. 9 Before starting to charge the battery, make sure

that the DC protector is pressed to I (RESET).

1. Start the engine.

2. Press in the DC protector.

1 I (RESET) 2 3 (OFF)

NOTICE

9 Be sure the economy control switch is turned off while charging the battery.

9 Be sure to connect the red battery charger lead to the positive (+) battery terminal, and connect the black lead to the negative () bat- tery terminal. Do not reverse these positions.

9 Connect the battery charger leads to the bat- tery terminals securely so that they are not disconnected due to engine vibration or other disturbances.

9 Charge the battery in the correct procedure by following instructions in the owners manual for the battery.

9 The DC protector turns off automatically if cur- rent above the rated flows during battery charging.

To restart charging the battery, turn the DC protector on by pressing its button to I (RESET). If the DC protector turns off again, stop charging the battery immediately and consult a Yamaha dealer.

TIP 9 Follow instructions in the owners manual for the

battery to determine the end of battery charging. 9 Measure the specific gravity of electrolyte to

determine if the battery is fully charged. At full charge, the electrolyte specific gravity is between 1.26 and 1.28.

9 It is advisable to check the specific gravity of the electrolyte at least once every hour to prevent overcharging the battery.

7CH-28199-18.indd 26 2015/04/01 13:54:34

WARNING 9 Electrolyte is poisonous and dangerous since

it contains sulfuric acid, which causes severe burns. Avoid any contact with skin, eyes or clothing and always shield your eyes when working near batteries. In case of contact, administer the following FIRST AID.

9 EXTERNAL: Flush with plenty of water. 9 INTERNAL: Drink large quantities of water or

milk and immediately call a physician. 9 EYES: Flush with water for 15 minutes and

seek prompt medical attention. 9 Batteries produce explosive hydrogen gas.

Therefore, keep sparks, flames, cigarettes, etc., away from the battery and provide sufficient ventilation when charging it in an enclosed space.

9 KEEP THIS AND ALL BATTERIES OUT OF THE REACH OF CHILDREN.

Operating range of DC power supply (Exclusively for charging 12 V battery) This power source is designed to charge batteries up to 40 Ah that are half-discharged. Do not charge bat- teries of a higher capacity than 40 Ah. 12 V battery The time required for recharging a battery varies depending on the discharge level of the battery. When the specific gravity of the battery reaches 1.26 to 1.28, charging is complete. When charging, check the bat- terys specific gravity once an hour. The average time for charging a half-discharged 40 Ah battery is approximately 5 hours. Be sure to check the battery fluid level before charging.

NOTICE

9 Do not connect any load to the battery or use the engine starter motor while charging. This causes high current to flow through the gener- ator which will burn out the coil.

9 Do not connect a VRLA (Valve Regulated Lead Acid) battery. To charge a VRLA battery, a spe- cial (constant-voltage) battery charger is required.
