Power Load Planning & Management

WARNING

NEVER exceed the rated wattage capacity of your generator.

OVERLOADING may cause SERIOUS DAMAGE to the generator and attached electrical devices, and may result in fire.

Your generator MUST BE SIZED PROPERLY to provide both the running and starting (surge) wattage of the devices you will be powering. Before using your generator, determine the running and starting wattage requirements of all the electrical devices you will be powering simultaneously.

The sum of the running and starting wattages of the devices being powered must not exceed the continuous output rating of your generator. (The continuous output rating of your generator is listed in the “Specifications” section of this manual.) Note that:

•

Devices without electric motors such as light bulbs, radios, and televisions have the same running and starting wattage.

•

Devices with electric motors such as refrigerators, compressors, and hand tools typically require a starting wattage that is 3 to 5 times greater than the running wattage.

The running and starting wattage requirements are often listed on a device’s nameplate. If wattage is not given on the device’s nameplate, the wattage may be calculated by multiplying the nameplate voltage by nameplate amperage, Watts = Volts X Amps.

Example conversion to watts:

120 Volts X 5 Amps = 600 Watts

If only the running voltage is given on the nameplate for a device with an electric motor, the starting wattage can be approximated to be three to five times the running wattage.

Estimates for the running wattage requirements for common devices are listed in Table 4 below.

Guidance for starting wattages is provided in the table’s footnotes.

(b) For extremely hard to start loads such as air conditioners and air compressors, consult the equipment dealer to determine maximum wattage

To calculate the running and starting wattage requirements for the devices you will be powering, follow these steps:

1.

Make a list of all electrical devices you will be powering at the same time with the generator.

2.

List the greater of the running or starting wattage next to each device as obtained from the devices’ nameplate or

Table 4 . If only the running wattage for a device with an electric motor is known, the starting wattage can be estimated to be at least 3 times the running wattage.

3.

Add the wattages for all devices on your list. This total must be lower than the continuous output rating of your generator.

Example:

In this example, the generator must have a continuous output of at least 6275 W in order to power all of the devices simultaneously.

STAGGERING LOADS

You can increase the number of devices your generator can power by staggering the load on the generator. For example, you could alternately power your refrigerator and air conditioner for limited periods of time -- powering only one of the devices at a time and never powering both at the same time.

2. Planning the Power Load

Plan your power load so that you do not exceed the generator’s rated capacity.

See the “Power Load Planning & Management” section of this manual to review how to plan and manage power loads for the generator.

3. Set-up either as a BUILDING BACK-UP or PORTABLE Power Source

This generator is designed to provide up to 7200W of continuous electrical power. It can supply electricity in two ways:

1.

As a back-up, standby power source for a building. For this application, you must arrange for a licensed electrician to connect the generator to your building’s electrical system via the installation of an UL-approved transfer switch. The transfer switch must be installed in accordance with building electrical code and guidelines supplied by your power company.

2.

As a portable power source

. You can plug appliances or tools directly into the generator’s electrical outlets.

Specific requirements for each are given below.

Note: Regardless of whether you use your generator as a back-up power source connected to a building or as a portable power source, you must not overload the generator. Overloading may cause serious damage to the generator and attached electrical devices.

Using as a

Back-up Power

Source for a

Building

Contact a licensed electrician to install an UL-approved transfer switch if you want to use your generator as a back-up power source for a building.

What does a transfer switch do? It: a) Safely connects the generator to your building’s electrical system by isolating your generator from your utility company’s power lines,

AND b) Connects your generator to a critical subset of your building’s circuits that are needed for emergency power needs.

If your generator will be connected to your building’s electrical system, it

MUST ALWAYS be isolated from the utility power grid with a UL-approved transfer switch installed by a licensed electrician in compliance with all applicable building and electrical codes, and in accordance with guidelines supplied by your power company.

DANGER:

A transfer switch must be installed in order to isolate your generator from the utility power grid. If your generator is NOT properly isolated from the utility system, serious hazards will arise:



When your generator is running, its output will back feed into the utility power line and transformer that are normally used to provide you with power. The transformer will step up the current to the normal line voltage. An unsuspecting utility line worker working on what he thinks is a deactivated line could be electrocuted.

13


Using as a

Portable Power

Source



If your generator is connected (running or not) when utility power is restored, your generator will be destroyed. It could also explode or cause fire.

In addition to isolating your generator from the utility system, the transfer switch connects your generator to a limited set of circuits in your building that have been chosen as critical to operate during a power outage.

This generator can power up to 7200 watts, which may not power your entire home or farm outbuilding -- you must work with the installing electrician to determine which devices/appliances you wish to power during an outage.

The electrician can help you determine which circuits and devices can be powered simultaneously without overloading the generator.

(See the previous section of this manual entitled “Power Load Planning &

Management” for more information on load application and selection.)

When using the generator as a portable power source, you can plug electric devices and appliances directly into the generator’s electrical outlets.

There are two different kinds of electrical outlets on the generator:

1.

One 120/240 Volt, 30 Amp locking receptacle (NEMA L14-30R locking receptacle compatible with L14-30P mating plug).

2.

One 120 Volt, 20 Amp duplex straight-blade receptacle (NEMA 5-

20R duplex receptacle compatible with NEMA 5-20P or 5-15P mating plugs).

NEMA

5-20R

NEMA

L14-30R

Duplex

(See more technical detail about these receptacles and their associated circuit breakers in the “Machine Component Identification” section of this manual.)



Make sure you plug each electrical device/appliance into the correct generator outlet based on the device’s plug configuration and voltage/amperage rating. Never exceed the amperage rating of an outlet.

14




Extension cords may be used to power devices that are located at a distance from the generator. However, use only UL-listed, outdoor-rated, grounded extension cords of the proper size. Additionally, if using the generator in damp or highly electrical conductive areas or on construction jobsites, always use ground fault circuit interrupter (GFCI)-equipped extension cords to prevent electrical shock. Use Table 5 below to choose an adequately sized extension cord according to the amperage of the device being used and the length of the cord.

4. Select a Suitable Site

Before using the generator, you must select a suitable OUTDOOR location for installation and operation of your generator.

•

If you will be mounting the generator to a concrete slab, you must choose the location of the slab according to all the criteria listed below.

•

If the generator will be mounted to a trailer, you should follow all the criteria listed below to select a suitable location each time you use the generator.

WARNING:

You must choose a suitable site for operating your generator to avoid equipment damage and/or injury and possible death from carbon monoxide poisoning, electric shock, or fire.

Choose a site that meets all of the criteria specified.

Site/Location Criteria:

Dry, level surface The generator should be positioned on a dry, firm, level surface.

Ensure that the generator will sit during operation. Apply the tractor’s parking brake, and if trailer-mounted block the trailer’s wheels to prevent sliding and shifting.

Outdoors only – dangerous carbon monoxide exhaust

WARNING: Carbon monoxide poisoning hazard

The exhaust from your tractor contains carbon monoxide (CO), a poisonous gas that can kill. You cannot smell it, see it, or taste it.

Follow the directions below for choosing a location to operate your generator in order to avoid carbon monoxide poisoning.

The location you choose to operate the generator must be OUTDOORS and away from all air intakes :

•

Never run the generator or tractor inside any closed or semi-enclosed spaces (even if outdoors), including homes, garages, basements, sheds, or boxes. These spaces can trap poisonous gases, even if you run a fan or open windows.

•

Place the tractor so that the exhaust fumes will not be directed towards people or building air intakes.

•

Ensure that working, battery-operated or battery back-up carbon monoxide alarms are used in any dwelling/structure that is in close proximity to the running generator.

Adequate cooling ventilation

The generator needs adequate, unobstructed flow of air to allow for proper cooling of generator head.

•

Situate so there is adequate clearance around generator to allow for cooling airflow so that heat does not build up. Never block vent slots.

The closest object should be at 7 feet away from vents.

16


•

Do not run the generator in close proximity to other heat-generating equipment, such as another generator. The combined heat that is generated may raise air temperature in the immediate area and there will not be adequate cooling ventilation.

•

Do not allow debris to accumulate and block airflow.

•

Do not operate with a tarp, blanket, or cover surrounding the generator.

Hot tractor exhaust clearance

The exhaust gas from your tractor is extremely hot and can cause combustible materials to catch on fire.

•

Position tractor at a safe distance from all nearby combustible materials and buildings/structures. Refer to your tractor manual to determine the safe clearance distance required for hot tractor exhaust in particular.

• Keep a fire extinguisher rated “ABC” nearby. Keep it properly charged and be familiar with its use.

No wet conditions Choose a location where the generator will NOT be exposed to rain, snow, or direct sunlight.

Exposure to water can cause electric shock.

You may operate the generator under an outdoor, canopy-like structure of heat-resistant material that is open on all sides. Make sure that all parts of canopy are:

• at least 7’ from generator

• at an adequate safe clearance from hot tractor exhaust.

Allow for adequate clearance above generator so that heat from generator does not build up.

Away from dust/dirt

Hearing protection

Do not use the generator in extremely dusty or dirty conditions.

Excessive dust and dirt can cause premature failure of the machine.

Generators can produce noise levels of up to 95 dB in close proximity, which can be dangerous to human hearing with prolonged exposure.

(This is in addition to the noise produced by the tractor.)

Hearing protection may be required for persons working within 15-20 feet of the running generator for an extended period of time.

17


5. Mounting the generator

This generator must be securely mounted on a reinforced concrete slab or a PTO generator trailer before it is connected to your tractor’s PTO.* This will prevent the generator from flipping due to the rotational torque of the PTO.

The slab or trailer you use must be of adequate size and strength to withstand up to

101.7 pound-foot of operating torque without flipping or structural failure.

WARNING: Failure to properly mount and secure the generator may cause the unit to flip violently during use, which could cause severe injury to the operator or bystanders, or damage to surrounding objects.

Failure to properly mount the generator is not only unsafe, but will void the manufacturer’s warranty.

* Instructions for connecting generator to tractor PTO is provided later in this manual in the Operation section, “Step 3. Connecting to the Tractor”.

Mounting to a trailer

Mount to a trailer if you plan to use the generator as a portable source of power.

WARNING:

Never mount to a trailer that is not wide enough or strong enough to handle the operating torque. An inadequate trailer may flip or fail due to generator’s operating torque, potentially causing injury or death.

1. Use only a wide base trailer that is specifically designed for mounting a

PTO generator.

•

A PTO generator trailer is designed to be of adequate size and strength to withstand the generator’s operating torque without flipping or structural failure. o The trailer wheelbase must be wide enough to prevent flipping. o The trailer base must be constructed of thick enough steel to prevent metal fatigue from the constant vibration of the generator.

•

A trailer specifically designed for use with PTO generators rated up to

60,000 Watts is available from NorthStar -- Item #165959.

2. Mount the generator on the trailer so it is: o Balanced forward of the trailer axle to prevent the trailer from tipping backward. o Centered side-to-side between the trailer’s wheels to minimize the possibility the trailer will flip due to operating torque.

If using the NorthStar PTO trailer (Item #165959), specific mounting bolt patterns are illustrated in the trailer’s Owner’s Manual for various

NorthStar PTO generator models.

3. Bolt the generator to the trailer base using four, 5/8” grade 5 bolts. See the next section: “Mounting to a concrete slab”, Figure 6.

18

Mounting to a concrete slab


If you will be using the generator in a permanent location, you may mount the generator to a reinforced concrete slab.

1. Choose a location for the slab that is as close to the load as possible (to minimize voltage drop) and which also meets all the criteria specified in the previous section, “

4. Select a Suitable Location

”.

2. The slab must: o Be of adequate size and weight to properly anchor the generator and resist flipping under operating torque. Typically the slab will need to be at least 2 feet x 2 feet x 4 inches thick. o Be reinforced with rebar in a direction perpendicular to the PTO shaft.

Rebar will strengthen the concrete to resist cracking and breaking as a result of operating torque and vibration. o Provide adequate elevation to ensure that the PTO driveline angle between the generator and tractor will not exceed 15 degrees. Note:

The smaller the angle, the longer the driveline will last.

For technical guidance on the design and construction of reinforced concrete slabs, refer to the American Concrete Institute (ACI) web site at www.concrete.org. The ACI has published several Technical Committee documents concerning the design and construction of concrete slabs.

WARNING:

Never attempt to mount generator to a slab that is not large enough or strong enough to withstand the operating torque. Slab failure could result in the generator flipping violently and possibly causing injury or death to those nearby.

3. Mount the plates to the concrete slab using four, grade 5, size 5/8” bolts.

6. Grounding the generator

Always ensure the generator is properly grounded to prevent electrical shock.

You must always ground the generator by the following method when using the generator as a portable electrical source:

1)

Drive a ¾” or 1” copper pipe or rod into the ground close to the generator. The pipe/rod must penetrate moist earth – the depth required will be dictated by local soil conditions.

Consult with an electrician.

2) Connect an approved ground clamp to the pipe.

3) Run an 8 gauge wire from the clamp to the generator grounding screw located on the rear of the generator head.

4) Do not connect the generator grounding post to a water pipe or a ground used by a radio system.

3. Connecting to the Tractor

Follow the instructions in this section to connect the generator to the tractor’s PTO via a driveline shaft (purchased separately).

Acquire PTO driveline shaft

Acquire a synchronized 1-3/8”, 6 spline PTO driveline rated at 24 HP minimum.

A suitable PTO driveline, available from Northern Tool ( Item #165936 ), includes the following advanced safety features:

•

A telescoping shaft o to provide flexible accommodation of mounting distance between tractor and generator o to allow for dynamic compression and stretching while turning or driving a trailer-mounted generator over uneven ground.

•

Protrusion-free end yokes with slide collars that lock into place.

•

An internal cable stop to prevent separation of driveline halves.

•

A non-rotating tubular shaft guard with anchoring chain, plus shield cones that cover the rotating yokes with a 2” overlap

•

Grease zerks to allow for proper lubrication of driveline joints.

It is strongly recommended that any driveline utilized have these safety features.

Attach PTO driveline shaft

Connect the PTO driveline shaft to the tractor and generator:

1.

Align the tractor and generator to minimize the driveline angle in both the horizontal and vertical planes; it should be as near to a direct line in all directions as possible. The angle should never exceed 15° in any direction.

Note: Proper alignment will increase the life of the power takeoff shaft, reduce wear on the bearings of the PTO and generator, and reduce vibration.

2.

Ensure that the tractor PTO is disengaged and the tractor is turned OFF.

3.

Connect one end of the PTO driveline shaft to the generator’s input shaft.

4.

Connect the other end to the tractor PTO stub.

WARNING :

Make sure PTO driveline shaft is securely locked at both ends. Unlocked

PTO shafts can whip or become dangerously airborne.

Secure driveline guard

& check shields

1.

A driveline GUARD must ALWAYS be used with the driveline shaft.

Secure the driveline guard according to manufacturer’s instructions.

2.

Make sure the tractor and generator shields are in place at both ends of the driveline shaft: o On the tractor where the driveline connects to the PTO stub o On the generator where the driveline connects to the input shaft.

WARNING :

Never operate the generator without proper PTO guarding, including a freely rotating shaft guard as well as tractor and generator shields at both ends. Clothing or hair can become rapidly entangled in unguarded rotating PTO shaft or connections, resulting in serious injury or death.

4. Starting the Generator

To start the generator:

1.

Start the tractor with the PTO control in the “disengaged” position.

2.

While seated on the tractor and the engine at idle, engage the PTO.

3.

Slowly increase the throttle until the needle in the generator voltmeter is at or above the black line in the green area.

5. Connecting Loads

You will want to be careful when connecting loads so as not to overload the generator, especially if you are powering devices with motors that require a higher starting power load.

Instructions are provided below for connecting loads when you are using the generator: o As a portable power source o Connected to a building as a back-up power source

WARNING :

Do not overload generator. Make sure that combined starting and running loads do not exceed rated capacity of generator. Overloading the generator can cause damage to the generator and attached electrical devices, and may result in fire.

Using as a

Portable Power

Source

Connect electrical loads one at a time according to the following instructions:

1.

Allow engine to reach operating speed by allowing it to warm up for approximately 5 minutes before connecting electrical devices.

2.

After engine is warmed up, begin connecting the loads one at a time.

WARNING : Stay clear of the rotating PTO driveline!

Start with those that require the highest wattage first. The recommended sequence is as follows: a.

Connect items with motors such as refrigerators, freezers, air conditioners, or small hand tools, one at a time. Let each motor stabilize before connecting the next device. b.

Connect any lights you are planning on powering. c.

Connect voltage sensitive equipment such as electronics via surge protectors. Plug devices such as TV’s, computers, and microwaves into a UL listed voltage surge protector, then plug the surge protector into the generator.

3.

After connecting each load, return to the driver’s seat. Readjust the throttle until the needle on the generator’s voltmeter is close to the black line in the green area. o If the needle will not rise to the green area no matter what the engine speed, the generator is either overloaded or there is a problem. o Shut off the tractor and refer to the Troubleshooting guide at the end of this manual for assistance with possible problems.

Also check your tractor’s PTO rating to make sure it is capable of producing a minimum of 24 HP at 540 RPM. This is not necessarily equivalent to the HP rating for the tractor itself.

Building


WARNING :

The generator must be run at the correct speed in order to produce the proper electrical voltage and frequency. Failure to do so could result in damage to equipment powered by the generator and possible injury to the individual.

Note: All engines have a tendency to slow down when a load is applied.

When electrical loads are connected to the generator, the engine is more heavily loaded and as a result the speed drops slightly.

This slight decrease in speed, together with the voltage drop within the generator itself, results in a slightly lower voltage when the generator is loaded to its full capacity than when it is running with no load. Additionally, there may be small brief surges and drops in voltage as motors connected to the generator cycle on or off.

The slight variation in voltage, as long as the needle remains in the green area, has no appreciable effect in the operation of motors, lights, and most appliances.

Each transfer switch installation will be unique. Proper instructions for how to safely bring the generator online with the building’s electrical system should be provided by the installing electrician, who should also provide personal instruction to the owner/operator.

Failure to follow the proper procedure as provided by the electrician could expose persons to the hazards noted above.

Note: After you have brought the generator online with the transfer switch, you will need to adjust the tractor’s throttle speed to maintain correct output voltage under load. Adjust the throttle until the needle on the generator’s voltmeter is close to the black line in the green area. (See more detail about maintaining proper voltage in the instructions given above for using the generator as a portable power source.)
