This is a spec roll from OM-2175A (500061A) for release of STD and
DLX configurations.
Note: the 60 kVA is similar to the 90 kVA with the following differences:
•Air cleaner and related air intake components
•AC Ammeter (different ranges)
•ID Resistor (different Power Module Panel assembly)

Safety Warnings and Cautions
WARNING
ELECTRIC SHOCK can KILL. Do not touch live electrical parts.
ELECTRIC ARC FLASH can injure eyes, burn skin, cause equipment damage, and
ignite combustible material. DO NOT use power cables to break load and prevent tools
from causing short circuits.
IMPROPER PHASE CONNECTION, PARALLELING, OR USE can damage this and
attached equipment.
IMPORTANT
Protect all operating personnel. Read, understand, and follow all instructions in the
Operating/Instruction Manual before installing, operating, or servicing the equipment.
Keep the manual available for future use by all operators.
WARNING
CALIFORNIA PROPOSITION 65 - DIESEL ENGINES. Diesel engine exhaust and
some of its constituents are known to the State of California to cause cancer, birth
defects and other reproductive harm.
1) General
Equipment that supplies electrical power can cause serious injury or death, damage to other equipment or
property. The operator must strictly observe all safety rules and take precautionary actions. Safe practices
have been developed from past experience in the use of power source equipment. While certain practices
below apply only to electrically powered equipment, other practices apply to engine-driven equipment, and
some practices to both.
2) Shock Prevention
Bare conductors, terminals in the output circuit, or ungrounded, electrically live equipment can fatally shock a
person. Have a certified electrician verify that the equipment is adequately grounded and learn what
terminals and parts are electrically HOT. Avoid hot spots on machine. Use proper safety clothing,
procedures, and test equipment.
The electrical resistance of the body is decreased when wet, permitting dangerous currents to flow through it.
When inspecting or servicing the equipment, do not work in damp areas. Stand on a dry rubber mat or dry
wood, and use insulating gloves when dampness or sweat cannot be avoided. Keep clothing dry, and never
work alone.
a) Installation and Grounding of Electrically Powered Equipment
This equipment must be installed and maintained in accordance with the National Electrical Code,
ANSI/NFPA 70, or other applicable codes. A power disconnect switch or circuit breaker must be
located at the equipment. Check the nameplate for voltage, frequency, and phase requirements. If
only 3-phase power is available, connect any single-phase rated equipment to only two wires of the 3-
phase line. DO NOT CONNECT the equipment grounding conductor (lead) to the third live wire of
the 3-phase line, as this makes the equipment frame electrically HOT,which can cause a fatal shock.

Safety Warnings
Page 2
Always connect the grounding lead, if supplied in a power line cable, to the grounded switch box or
building ground. If not provided, use a separate grounding lead. Ensure that the current (amperage)
capacity of the grounding lead will be adequate for the worst fault current situation. Refer to the
National Electrical Code ANSI/NFPA 70 for details. Do not remove plug ground prongs and use
correctly mating receptacles.
b) Output Cables and Terminals
Inspect cables frequently for damage to the insulation and the connectors. Replace or repair cracked
or worn cables immediately. Do not overload cables. Do not touch output terminal while equipment
is energized.
3) Service and Maintenance
This equipment must be maintained in good electrical condition to avoid hazards stemming from
disrepair. Report any equipment defect or safety hazard to the supervisor and discontinue use of the
equipment until its safety has been assured. Repairs should be made by qualified personnel only.
Before inspecting or servicing this equipment, take the following precautions:
a) Shut off all power at the disconnecting switch, or line breaker, or by disconnecting battery, before
inspecting or servicing the equipment.
b) Lock switch OPEN (or remove line fuses) so that power cannot be turned on accidentally.
c) Disconnect power to equipment if it is out of service.
d) If troubleshooting must be done with the unit energized, have another person present who is trained
in turning off the equipment and providing or calling for first aid.
4) Fire And Explosion Prevention
Fire and explosion are caused by electrical short circuits, combustible material near engine exhaust pipes,
misuse of batteries and fuel, or unsafe operating or fueling conditions.
a) Electrical Short Circuits and Overloads
Overloaded or shorted equipment can become hot enough to cause fires by self-destruction or by
causing nearby combustibles to ignite. For electrically powered equipment, provide primary input
protection to remove short circuited or heavily overloaded equipment from the line.
b) Batteries
Batteries may explode and/or give off flammable hydrogen gas. Acid and arcing from a ruptured
battery can cause fires and additional failures. When servicing, do not smoke, cause sparking, or use
open flame near the battery.
c) Engine Fuel
Use only approved fuel container or fueling system. Fires and explosions can occur if the fuel tank is
not grounded prior to or during fuel transfer. Shut unit DOWN before opening fuel tank cap. DO NOT
completely fill tank, because heat from the equipment may cause fuel expansion overflow. Remove
all spilled fuel IMMEDIATELY, including any that penetrates the unit. After clean-up, open equipment
doors and blow fumes away with compressed air.

Safety Warnings

5) Toxic Fume Prevention
Carbon monoxide - Engine exhaust fumes can kill and cause health problems. Pipe or vent the exhaust
fumes to a suitable exhaust duct or outdoors. Never locate engine exhausts near intake ducts of air
conditioners.
6) Bodily Injury Prevention
Serious injury can result from contact with fans or hot spots inside some equipment. Shut DOWN such
equipment for inspection and routine maintenance. When equipment is in operation, use extreme care in
doing necessary troubleshooting and adjustment. Do not remove guards while equipment is operating.
7) Medical and First Aid Treatment
First aid facilities and a qualified first aid person should be available for each shift for immediate treatment
of all injury victims. Electric shock victims should be checked by a physician and taken to a hospital
immediately if any abnormal signs are observed.
EMERGENCY
FIRST AID
Call physician immediately. Seek additional assistance. Use First Aid techniques
recommended by American Red Cross until medical help arrives.
IF BREATHING IS DIFFICULT, give oxygen, if available, and have victim lie down.
FOR ELECTRICAL SHOCK, turn off power. Remove victim; if not breathing, begin
artificial respiration, preferably mouth-to-mouth. If no detectable pulse, begin external
heart massage. CALL EMERGENCY RESCUE SQUAD IMMEDIATELY.
8) Equipment Precautionary Labels
Inspect all precautionary labels on the equipment monthly. Order and replace all labels that cannot be
easily read.
