DCX2000 Portable Generator Safety Notes
The manufacturer cannot anticipate every circumstance that may involve a hazard, therefore, these warnings are not
comprehensive.
WARNING! FUMES HAZARD
Engine exhaust contains carbon monoxide gas, which can be deadly in closed or poorly
ventilated areas.
WARNING! ELECTRICAL HAZARD
• Generator must be properly grounded.
• Do not make or break any connections while generator is running.
• Do not place or operate the generator in standing water, or expose it to a forced spray of
water.
• Ensure cables do not cross hot surfaces or sharp edges. Inspect cables before and after
each use.
WARNING! FIRE HAZARD
• Never operate the generator near combustible materials.
• Never refuel the generator in the vicinity of open ames of heat sources. Do not smoke near
the generator.
• Do not refuel the generator while engine is running. Allow generator to cool before refueling.
• Fuel spillage cleanup is the responsibility of the operator and should comply with local codes
and regulations.
• For re safety, the generator must be properly connected, maintained, and in compliance
with applicable codes and regulations.
• Drain oil and empty the fuel tank before transporting. Fuel can leak from the ller cap if the
generator is tilted.
CAUTION!
• Prior to each use, inspect the generator for leaks and damage. Immediately repair or replace any
damaged parts.
• The generator must be operated on level ground, not to exceed 15° slant.
• Use only vendor-authorized repair parts.

1.0 Introduction
The Alphagen DCX2000 portable DC generator supplies DC voltage to a power supply battery bus when
commercial AC power is not available. The generator is designed to be temporarily connected to the DC bus
of a standard Alpha 36V uninterruptable power supply (UPS). Upon loss of commercial AC power, the existing
batteries immediately supply the power supply inverters. After some interval of battery discharge, an operator
deploys the portable generator at the site to supply power to the DC bus.

2.0 Operation
2.1 Oil Level
WARNING! ELECTRICAL HAZARD
Power OFF the generator engine and place on a level surface before servicing.
CAUTION!
• Using non-detergent oil or 2-stroke engine oil will shorten service life and void the warranty. Use only
high-detergent, premium quality, 4-stroke engine oil, certied to meet U.S. automobile manufacturer’s
requirements for API Service Classication SG/SF/SJ/SL/SM/SN. Use synthetic SAE 10W-40
viscosity oil unless operating at ambient temperatures below 32°F (0°C). For temperatures below
32°F, use synthetic SAE 0W-40 viscosity oil.
• Change the oil in a new engine within 4-6 hours of operation to clean any contamination or
manufacturing debris.
• Running the engine with low oil can cause serious damage.
• The Low Oil Alarm System will automatically stop the engine before the oil level falls below a safe
limit. To avoid an unexpected shutdown, inspect the oil level regularly.
Dipstick
Tools Required:
#2 Philips Head Screwdriver
Oil Drain Pipe
Procedure:
1. Remove the maintenance cover.
2. Using the slots in the oil drain pipe, remove the dipstick, wipe with a clean rag and reinsert, screw
down until tight.
3. Remove the dipstick to check the oil level.
4. If the oil level is below the lower level of the dipstick, rell to the top of the upper level marking. Do not
overll.
5. Reinsert the dipstick and screw down until tight.

2.0 Operation, continued
2.2 Fuel Level
WARNING! FIRE & FUMES HAZARD
Gasoline is extremely ammable and can be explosive. Refuel in a well-ventilated area
with the engine OFF. Keep all smoking materials, sparks, and other sources of combustion
away from the generator during refueling.
The area must be free of spilled fuel before starting the engine. Avoid repeated or
prolonged contact with skin or exposure to vapor. KEEP OUT OF REACH OF CHILDREN.
Only use regular unleaded gasoline with the DCX2000 Generator. The fuel tank has a capacity of 1.7
gallons (6.5 Liters).
Procedure:
1. If the fuel level is low, rell to the top of the fuel strainer.
2. After refueling, tighten the fuel cap securely.
CAUTION!
Do not use an alternate fuel blend that contains more than 10% ethanol. Do not use gasoline
containing methanol. An octane rating of 87 or higher is recommended. Fuel system damage or engine
performance problems resulting from the use of fuels that contain an improper alcohol blend are not
covered under warranty.
