SAFETY INFORMATION
ENGINE SAFETY
WARNING
DO NOT place hands or fingers inside engine
compartment when engine is running.
NEVER operate the engine with heat shields or guards removed.
Keep fi ngers, hands hair and clothing away from all moving parts to prevent injury.
DO NOT remove the radiator cap while the engine is hot. High pressure boiling water will gush out of the radiator and severely scald any persons in the general area of the generator.
DO NOT remove the coolant drain plug while the engine is hot. Hot coolant will gush out of the coolant tank and severely scald any persons in the general area of the generator.
DO NOT remove the engine oil drain plug while the engine is hot. Hot oil will gush out of the oil tank and severely scald any persons in the general area of the generator.
CAUTION
NEVER touch the hot exhaust manifold,
muffl er or cylinder. Allow these parts to cool before servicing equipment.
NOTICE
NEVER run engine without an air fi lter or with a dirty air fi lter. Severe engine damage may occur. Service air fi lter frequently to prevent engine malfunction.
Wet stacking is a common problem with diesel engines which are operated for extended periods with light or no load applied. When a diesel engine operates without suffi cient load (less than 40% of the rated output), it will not operate at its optimum temperature. This will allow unburned fuel to accumulate in the exhaust system, which can foul the fuel injectors, engine valves and exhaust system, including turbochargers, and reduce the operating performance.
In order for a diesel engine to operate at peak effi ciency,
it must be able to provide fuel and air in the proper ratio and at a high enough engine temperature for the engine to completely burn all of the fuel.
Wet stacking does not usually cause any permanent
damage and can be alleviated if additional load is applied to relieve the condition. It can reduce the system performance and increase maintenance. Applying an increasing load over a period of time until the excess fuel is burned off and the system capacity is reached usually can repair the condition. This can take several hours to burn off the accumulated unburned fuel.
State Health Safety Codes and Public Resources Codes specify that in certain locations, spark arresters must be used on internal combustion engines that use hydrocarbon fuels. A spark arrester is a device designed to prevent accidental discharge of sparks or fl ames from the engine exhaust. Spark arresters are qualifi ed and rated by the United States Forest Service for this purpose. In order to comply with local laws regarding spark arresters, consult the engine distributor or the local Health and Safety Administrator.
NEVER tamper with the factory settings of the engine or engine governor. Damage to the engine or equipment can result if operating in speed ranges above the maximum allowable.
PAGE 8 — DCA400SSI GENERATOR • OPERATION AND PARTS MANUAL — REV. #2 (11/03/08)
SAFETY INFORMATION
FUEL SAFETY
DANGER
DO NOT start the engine near spilled fuel or combustible
fl uids. Diesel fuel is extremely fl ammable and its vapors can cause an explosion if ignited.
ALWAYS refuel in a well-ventilated area, away from sparks and open fl ames.
ALWAYS use extreme caution when working with fl ammable liquids.
DO NOT fi ll the fuel tank while the engine is running
or hot.
DO NOT overfi ll tank, since spilled fuel could ignite if it comes into contact with hot engine parts or sparks from the ignition system.
Store fuel in appropriate containers, in well-ventilated areas and away from sparks and fl ames.
NEVER use fuel as a cleaning agent.
DO NOT smoke around or near the
equipment. Fire or explosion could result from fuel vapors or if fuel is spilled on a hot engine.
TOWING SAFETY
CAUTION
Check with your local county or state safety towing regulations, in addition to meeting
Department of Transportation (DOT) Safety Towing Regulations, before towing
your generator.
Refer to MQ Power trailer manual for additional safety information.
In order to reduce the possibility of an accident while transporting the generator on public roads, ALWAYS make sure the trailer that supports the generator and the towing vehicle are mechanically sound and in good operating condition.
ALWAYS shutdown engine before transporting
Make sure the hitch and coupling of the towing vehicle are rated equal to, or greater than the trailer “gross vehicle weight rating.”
ALWAYS inspect the hitch and coupling for wear. NEVER tow a trailer with defective hitches, couplings, chains, etc.
Check the tire air pressure on both towing vehicle and trailer. Trailer tires should be infl ated to 50 psi cold. Also check the tire tread wear on both vehicles.
ALWAYS make sure the trailer is equipped with a safety chain.
ALWAYS properly attach trailer’s safety chains to towing
vehicle.
ALWAYS make sure the vehicle and trailer directional, backup, brake and trailer lights are connected and working properly.
DOT Requirements include the following:
• Connect and test electric brake operation.
• Secure portable power cables in cable tray with tie wraps.
The maximum speed for highway towing is 55 MPH unless posted otherwise. Recommended off-road towing is not to exceed 15 MPH or less depending on type of terrain.
Avoid sudden stops and starts. This can cause skidding, or jack-knifi ng. Smooth, gradual starts and stops will improve towing.
Avoid sharp turns to prevent rolling.
Trailer should be adjusted to a level position at all times when towing.
Raise and lock trailer wheel stand in up position when towing.
Place chock blocks underneath wheel to prevent rolling while parked.
Place support blocks underneath the trailer’s bumper to prevent tipping while parked.
Use the trailer’s swivel jack to adjust the trailer height to a level position while parked.

INSTALLATION
Typical Generator Grounding ApplicationFigure 2.
PAGE 14 — DCA400SSI GENERATOR • OPERATION AND PARTS MANUAL — REV. #2 (11/03/08)
INSTALLATION
OUTDOOR INSTALLATION
Install the generator in a area that is free of debris, bystanders, and overhead obstructions. Make sure the generator is on secure level ground so that it cannot slide or shift around. Also install the generator 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.
CAUTION
Pay close attention to ventilation when operating the generator inside tunnels and caves. The engine exhaust contains noxious elements. Engine exhaust must be routed to a ventilated area.
GENERATOR GROUNDING
To guard against electrical shock and possible damage to the equipment, it is important to provide a good EARTH ground.
Article 250 (Grounding) of the National Electrical Code (NEC) provides guide lines for proper grounding and specifi es 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:
Use one of the following wire types to connect the 1. generator to earth ground.
Copper - 10 AWG (5.3 mm2) or larger.a.
Aluminum - 8 AWG (8.4 mm2) or larger.b.
When grounding the generator (Figure 2) connect the 2. ground cable between the lock washer and the nut on the generator and tighten the nut fully. Connect the other end of the ground cable to earth ground.
INDOOR INSTALLATION
Exhaust gases from diesel 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.
MOUNTING
The generator must be mounted on a solid foundation (such as concrete) and set fi rmly on the foundation to isolate vibration of the generator when it is running. The generator must set at least 6 inches above the fl oor or grade level (in accordance to NFPA 110, Chapter 5-4.1). DO NOT remove the metal skids on the bottom of the generator. They are to resist damage to the bottom of the generator and to maintain alignment.
NEC article 250-52(c) specifi es that the earth ground rod 3. should be buried a minimum of 8 ft. into the ground.
NOTICE
When connecting the generator to any buildings electrical system ALWAYS consult with a licensed electrician.
DCA400SSI GENERATOR • OPERATION AND PARTS MANUAL — REV. #2 (11/03/08) — PAGE 15
GENERAL INFORMATION
GENERATOR
The MQ Power Model DCA400SSI is a 320 kW generator (Figure 3) that is designed as a high quality portable (requires a trailer for transport) power source for telecom sites, lighting facilities, power tools, submersible pumps and other industrial and construction machinery.

The “Engine Operating Panel” is provided with the following:
Tachometer Emergency Stop Switch Water Temperature Gauge Oil Pressure Gauge Charging Ammeter Gauge Fuel Level Gauge Pre-Heat Lamp Engine Speed Switch Battery Switch Engine Alarm Lamps (5)
GENERATOR CONTROL PANEL
The “Generator Control Panel” is provided with the following:
Frequency Meter (Hz) AC Ammeter (Amps) AC Voltmeter (Volts) Ammeter Change-Over Switch Voltmeter Change-Over Switch Voltage Regulator Panel Light/Panel Light Switch 3-Pole, 1,000 amp Main Circuit Breaker “Control Box” (located behind the Gen. Control Panel)
Automatic Voltage Regulator• Current Transformer• Over-Current Relay• Voltage Rectifi er• Starter Relay• Engine Controller (Computer Controlled)• Voltage Change-Over Board
OUTPUT TERMINAL PANEL
The “Output Terminal Panel” is provided with the following:
Three 120/240V output receptacles (CS-6369), 50A Three auxiliary circuit breakers, 50A Two 120V output receptacles (GFCI), 20A Two GFCI circuit breakers, 20A Eight output terminal lugs (3Ø power) Battery Charger (Optional) Water Heater (Optional)
OPEN DELTA EXCITATION SYSTEM
The DCA400SSI generator is equipped with the state of the art “Open-Delta” excitation system. The open delta system consist of an electrically independent winding wound among stationary windings of the AC output section.
There are four connections of the open delta A, B, C and D. During steady state loads, the power from the voltage regulator is supplied from the parallel connections of A to B, A to D, and C to D. These three phases of the voltage input to the voltage regulator are then rectifi ed and are the excitation current for the exciter section.
When a heavy load, such as a motor starting or a short circuit occurs, the automatic voltage regulator (AVR) switches the confi guration of the open delta to the series connection of B to C. This has the effect of adding the voltages of each phase to provide higher excitation to the exciter section and thus better voltage response during the application of heavy loads.
The connections of the AVR to the AC output windings are for sensing only. No power is required from these windings.
The open-delta design provides virtually unlimited excitation current, offering maximum motor starting capabilities. The excitation does not have a “fi xed ceiling” and responds according the demands of the required load.
ENGINE
The DCA400SSI is powered by a 6 cylinder, water cooled, direct injection, turbocharged air-to-air ISUZU 6WG1X Diesel Engine. This engine is designed to meet every performance requirement for the generator. Reference Table 2 for engine specifi cations.
In keeping with MQ Power’s policy of constantly improving its products, the specifi cations quoted herein are subject to change without prior notice.
ELECTRIC GOVERNOR SYSTEM
The electric governor system controls the RPMs of the engine. When the engine demand increases or decreases, the governor system regulates the frequency variation to ±.25%.
EXTENSION CABLES
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 generator and point of use (load) is held to a minimum. Use the cable selection chart (Table 6) as a guide for selecting proper extension cable size.

LOAD APPLICATION
SINGLE PHASE LOAD
Always be sure to check the nameplate on the generator and equipment to insure the wattage, amperage, frequency, and voltage requirements are satisfactorily supplied by the generator 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 infl uenced by the effi ciency, power factor and starting system of the equipment.
NOTICE
If wattage is not given on the equipment’s name plate, approximate wattage may be determined by multiplying nameplate voltage by the nameplate amperage.
WATTS = VOLTAGE x AMPERAGE
The power factor of this generator is 0.8. See Table 5 below when connecting loads.
Power Factor By LoadTable 5.
Type of Load Power Factor
Single-phase induction motors 0.4-0.75
THREE PHASE LOAD
When calculating the power requirements for 3-phase power use the following equation:
NOTICE
If 3Ø load (kVA) is not given on the equipment nameplate, approximate 3Ø load may be determined by multiplying voltage by amperage by 1.732.
NOTICE
Motors and motor-driven equipment draw much greater current for starting than during operation.
An inadequate size connecting cable which cannot carry the required load can cause a voltage drop which can burn out the appliance or tool and overheat the cable. See Table 6.
When connecting a resistance load such as an incandescent lamp or electric heater, a capacity of up to the generating set’s rated output (kW) can be used.
Electric heaters, incandescent lamps 1.0
Fluorescent lamps, mercury lamps 0.4-0.9
Electronic devices, communication equipment

GENERATOR OUTPUTS
GENERATOR OUTPUT VOLTAGES
A wide range of voltages are available to supply voltage for many different applications. Voltages are selected by applying jumpers (6) to the voltage change-over board (Figure 12). To obtain some of the voltages as listed in Table 7 (see below) will require a fi ne adjustment using the voltage regulator (VR) control knob located on the control panel.
Voltage Change-Over Board
The voltage change-over board (Figure 12) is located on the control box, behind the generator control panel. This board has been provided for ease of voltage selection.
