WARNINGWARNING

WARNING

WARNINGWARNING

Before connecting this generators to any building’s electrical system, a licensed electrician must install an isolation (transfer) switch.

Serious injury or death may result without this transfer switch.

GA-6H/GA-6HA FAMILIARIZATION Generator

The Multiquip GA-6H and GA-6HA generators have been designed as a portable dual purpose power source for 60 Hz (single phase) lighting facilities, power tools, submersible pumps and other industrial and construction machinery.

These generators are mounted on rubber vibration isolators that have a steel base backplate which is attached to the protective steel pipe carrying frame. The protective carrying frame is made of steel tubing and fully wraps around the generators to protect against damage. See Figures 3A through 3E for the basic controls and indicators for the GA6H/GA-6HA generators.

These portable generators are supplied with a electrical

control box

control box is also placed on rubber isolators.

Control Box

The control box is provided with the following:

■

120/240V twist-lock output receptacle (single phase).

. To reduce vibration caused by the engine, the

The GA-6H/GA-6HA-series generators use a magnet attached to a flywheel to produce AC voltage from a lamp coil beneath the flywheel. As the magnetic passes the coil it produces approximately 19-22 AC volts.

This voltage (19-22 VAC) is then sent to the control box that contains three rectifying diodes:

Excitation (diode 1)

Battery (diode 2)

Slow Down (diode 3)

The AC voltage will pass through the excitation diode that converts the voltage to DC power.

This DC power is then sent to the excitation windings housed within the main windings commonly called the "stator".

This voltage is then transferred into the rotor through induction. The rotor contains two diodes within it which rectify the DC voltage and send it out through the main windings, as AC voltage.

Alternator

The alternator, a brushless revolving-field type, is permanently aligned to the engine through rigid coupling.

Engine

These generators are powered by a 11 HP, air-cooled, 4stroke

HONDA gasoline engine. Reference Table 2, for

engine specifications.

GA-6H/GA-6HA — LOAD APPLICATION

Single Phase Load — 60 Hz

Always be sure to check the nameplate on the generators and equipment to insure the wattage, amperage and frequency requirements are satisfactorily supplied by the generators for operating the equipment.

Generally, the wattage listed on the nameplate of the equipment is its rated output. Equipment may require 130— 150% more wattage than the rating on the nameplate, as the wattage is influenced by the efficiency, power factor and starting system of the equipment.

To determine the running wattage for your load, multiply the running wattage as indicated by steps 1, 2, and 3 below:

1. INCANDESCENT LOADS Lights, heaters and similar appliances. Total the running wattage and multiply by 1. Example: 29 light bulbs @ 100W each = 2.9 KW use a 3 KW generator.

2. SMALL MOTORS Drills and other small power tools. Total the running wattage and multiply by 2. Example:

NOTE

If wattage is not given on the equipment's name plate, approximate wattage may be

determined by multiplying nameplate voltage by the nameplate amperage.

3. LARGE MOTORS Submersible pumps, table saws etc.

WATTS = VOLTAGE x AMPERAGE The power factor of this generators is 1.0 See Table 3 below

when connecting loads.

Total the running wattage and multiply by 3. Example: A conveyor belt runs at 8 KW use a 24 KW generator.

1. Lifting Bail Eye – Attach a rope or chain to this lifting eye when lifting of the generators is required. Never stand underneath the generators while it is being lifted. Place lifting eye in down position when not in use.

2. AC-Voltmeter – This voltmeter indicates (with a mark) the rated 60 Hz (single-phase) output voltage. In addition the voltmeter can also be used as a diagnostic tool. If the voltmeter indicator (needle) is below the rated voltage, engine problems may exist (low/high RPM's). To prevent damage to the generators or power tools turn the generators OFF and consult your authorized Multiquip service dealer.

3. Idle Control Switch – The generators are provided with an automatic idle control device for noise suppression and reduced fuel consumption. The automatic idle control automatically engages under a no-load condition. With the automatic idle control switched “ON”, the engine revolutions will automatically drop to about 2600 rpm (low-speed operation) within 3 seconds after the load stops. When the operation is resumed, the engine speed is automatically increased to about 3600 rpm (high-speed operation) as soon as the load is connected.

bystanders

generators is on secure level ground so that it cannot slide or shift around. Also install the generators in a manner so that the exhaust will not be discharged in the direction of nearby homes.

The installation site must be relatively free from moisture and dust. All electrical equipment should be protected from excessive moisture. Failure to do will result in deterioration of the insulation and will result in short circuits and grounding.

Foreign materials such as dust, sand, lint and abrasive materials have a tendency to cause excessive wear to engine and alternator parts.

Pay close attention to ventilation when operating the generators inside tunnels and caves. The engine exhaust contains noxious elements.

Mounting

The generators should always be mounted on a flat level surface to isolate vibration of the generators when it is running. DO NOT place the generators on slopes, the possibility exists that the generators could slide.

Indoor Installation

Exhaust gases from gasoline engines are extremely poisonous. Whenever an engine is installed indoors the exhaust fumes must be vented to the outside. The engine should be installed at least two feet from any outside wall. Using an exhaust pipe which is too long or too small can cause excessive back pressure which will cause the engine to heat excessively and possibly burn the valves.

Eliminate the danger of deadly carbon monoxide gas. Remember that exhaust fumes from any gasoline engine are very poisonous if discharged in a closed room, but harmless if allowed to mix with the outside air. If the generators is installed indoors, you must make provisions for venting the engine exhaust to the outside of the building.

Generators Grounding

To guard against electrical shock and possible damage to the equipment, it is important to provide a good EARTH ground. Always use the ground terminal on the generators to ground the generator. Ground the generators from its ground

connector so that the resistance to ground is 500 ohms or less.

Article 250 (Grounding) of the National Electrical Code (NEC) provides guide lines for proper grounding and specifies that the cable ground shall be connected to the grounding system of the building as close to the point of cable entry as practical.

NEC articles 250-64(b) and 250-66 set the following grounding requirements:

1. Use one of the following wire types to connect the generators to earth ground.

a. Copper - 10 AWG (5.3 mm2) or larger. b. Aluminum - 8 AWG (8.4 mm2) or larger.

CAUTIONCAUTION

CAUTION

CAUTIONCAUTION

An electric shock is apt to happen when vibrators are used. Pay close attention to handling when operating vibrators and always use rubber boots and gloves to insulate the body from a short circuit.

GA-6H/GA-6HA A.C. GENERATORS — OPERATION & PARTS MANUAL — REV. #0 (06/02/05) — PAGE 21

2. When grounding the generators (Figure 3) connect the ground cable between the lock washer and the nut on the generators and tighten the nut fully. Connect the other end of the ground cable to earth ground.

3. NEC article 250-52(c) specifies that the earth ground rod should be buried a minimum of 8 ft. into the ground.

GA-6H/GA-6HA — INSTALLATION

Connecting the Ground

The nut and ground terminal on the generators should always be used to connect the generators to a suitable ground. The ground cable should be #8 size wire minimum.

At the generator, connect the terminal of the ground cable between the lock washer and the nut (Figure 5) and tighten the nut fully. Connect the other end of the ground cable to a suitable earth ground (ground rod).

General Inspection Prior to Operation

Ground Power Tools

When using power tools or electrical equipment requireing AC power from the generator, make sure connecting (power tool) cable (Figure 6) has a ground as shown in Figure.

Extension Cable

When electric power is to be provided to various tools or loads at some distance from the generator, extension cords are normally used. Cables should be sized to allow for distance in length and amperage so that the voltage drop between the generators and point of use (load) is held to a minimum. Use the cable selection chart (Table 4) as a guide for selecting proper cable size.
