1.2 Operating Safety

Familiarity and proper training are required for the safe operation of electrical equipment! Equipment operated
improperly or by untrained personnel can be dangerous! Read the operating instructions and familiarize yourself with
the location and proper use of all instruments and controls. Inexperienced operators should receive instruction from
someone familiar with the equipment before being allowed to operate the generator.

WARNING

NEVER operate generator when open containers

of fuel, paint, or other flammable liquids are near.

NEVER operate generator, or tools attached to the
generator, with wet hands.

NEVER use worn electrical cords. Severe electri­cal shock and equipment damage may result.

NEVER place flammable material or liquids near
generator.

NEVER operate generator indoors unless exhaust
fumes can be adequately ventilated.

the tools and equipment attached to the generator
must not exceed the load rating of the generator.

NEVER allow untrained personnel to operate or
service the generator. The generator set should
be set up by a trained electrician.

NEVER operate generator in standing water.

ALWAYS wear hearing protection when running

the unit with the doors open.

ALWAYS follow starting and stopping instructions
described in this manual. Know how to operate and
stop generator before starting it.

ALWAYS make a walk-around inspection of the
generator set before starting it. Open side doors
and visually inspect engine compartment for obvi­ous damage or the presence of foreign objects
which might affect operation.

ALWAYS keep generator at least three feet (one
meter) away from structures, buildings and other
equipment during use.

to backfeed into utility lines. This may result in electrocution of utility workers, fire or explosion. Connections to
a building’s electrical system must be made by a qualified electrician and comply with all applicable laws and
electrical codes.

ALWAYS position and operate generator on a firm,
level surface.

ALWAYS remove all tools and other loose items
from generator before starting it.

1A-3

1A OPERATION G50/G70/G85

1.3 Service Safety

Poorly maintained equipment can become a safety hazard! In order for the equipment to operate safely and properly
over a long period of time, periodic maintenance and occasional repairs are necessary. When servicing this
equipment always follow the instructions listed below.

WARNING

NEVER perform even routine service (oil/filter changes, cleaning, etc.)

unless all electrical components are shut down.

Before servicing this machine, make sure the engine start switch is turned to off “O”, the circuit breakers
are open (off), the emergency stop switch is closed (pushed in), and the negative terminal on battery is
disconnected. Attach a “DO NOT START” sign to the control panel. This will notify everyone that the unit is being
serviced and will reduce the chance of someone inadvertently trying to start the unit. If the unit is connected to
a remote start or transfer switch, make sure the remote switch is also off and tagged.

WARNING

Ground Connection

The generator must be connected to a good earthen ground for proper operating safety!

A central “equipment ground” is provided at the customer connection lugs. This point is connected directly to the
generator set base. All other system grounds are connected to this central point. Ground the generator in
accordance with the standards defined in national, state and local regulations.

WARNING

DO NOT attempt to open the radiator cap while the

unit is running or before the engine has cooled
down. Severe burns may result!

DO NOT allow water to accumulate around the base
of the generator set. If water is present, move the
generator and allow it to dry before servicing.

DO NOT service generator if clothing or skin is wet.

DO NOT allow untrained personnel to service this

equipment. Only trained electrical tech-nicians should
be allowed to service the electrical components of
this equipment.

DO NOT modify the equipment without ex-press
written approval from WACKER Corporation.

When cleaning the unit, DO NOT pressure wash
the control panel, generator end, or any other
electrical components. Never allow water to accu­mulate around the base of the generator set. If
water is present, DO NOT service!

ALWAYS replace all guards and safety devices
immediately after servicing.

ALWAYS let engine cool before transporting or ser­vicing.

ALWAYS remain aware of moving parts and keep
hands, feet and loose clothing away from moving parts
on generator and engine.

ALWAYS replace all guards, fasten doors and make
sure all safety devices operate properly after making

labels. Labels provide important operating
instructions and warn of dangers and hazards.

Check and tighten all external fasteners at regular
intervals.

Make sure slings, chains, hooks, ramps, jacks, and
other types of lifting devices are attached securely
and have enough weight-bearing capacity to lift or
hold the equipment safely. ALWAYS remain aware
of the position of other people around you when
lifting the generator.

1A-4

G50/G70/G85 OPERATION 1A

1.4 Operator Safety while using Internal Combustion Engines

to each other to reduce the possibility of an accident.

WARNING

ALWAYS check that the hitch and coupling on the

vehicle are rated equal to, or greater than, the trailer's
“gross vehicle weight rating” (GVWR).

ALWAYS connect breakaway cable safety hook to
the bumper or rear of the vehicle. DO NOT attach to
hitch.

ALWAYS inspect the hitch and coupling for wear or
damage. DO NOT tow trailer using defective parts!

ALWAYS make sure the coupling is securely fas­tened to the vehicle.

ALWAYS check tires on trailer for tread wear, infla­tion, and condition. Replace worn tires.

ALWAYS connect the safety chains.

If you believe your trailer has a defect which could cause a crash or could cause injury or death, you should
immediately inform the National Highway Traffic Safety Administration (NHTSA) in addition to notifying WACKER
Corporation.

If NHTSA receives similar complaints, it may open an investigation; and if it finds that a safety defect exists in
a group of vehicles, it may order a recall and remedy campaign. However, NHTSA cannot become involved in
individual problems between you, your dealer, or WACKER Corporation.

To contact NHTSA, you may either call the Auto Safety Hotline toll-free at 1-800-424-9393 (or 366-0129 in

LCD Read-out

The large LCD read-out on the metering panel simulta­neously displays both engine and generator information
while the unit is running.

During operation the top line displays vital generator
information: voltage, frequency in Hertz and amperage.
Information is displayed for all three phases on a rotating
basis, with the values for phase 1 being displayed first,
followed by phase 2 and then phase 3. In single phase
120/240 position, phase 1 reads L1-N, phase 2 reads
L1-L3, and phase 3 reads L3-N.

The bottom line of the panel monitors vital engine infor­mation and continuously displays: oil pressure, engine
coolant temperature, battery voltage and fuel level.

The engine running time can be displayed by using the
Engine Hours switch. Holding the switch up will allow the
panel to scroll through the engine fault set points, the
engine sender condition, and the time until the next
engine service is due (“Time to Service”). The Engine
Hours switch can also be used to lock in the voltage,
amperage and frequency readings for any one phase. To
lock in readings for one phase, push the Engine Hours
switch down.

the engine’s running hours, the periodic maintenance

timer, and the Engine Fault set points to be displayed.
Engine hours are accumulated only while the engine is
actually running.

Note:

When held down, this switch can be used to lock

in a specific display for a single phase.

1.14 Voltage Selector Switch

The voltage selector switch is located in a separate
enclosure on the generator on the opposite side of the
machine.

The selector switch is a three-position switch which
mechanically changes the connections between the gen­erator output leads and the terminal lugs on the genera­tor. This allows three different volt ranges to be selected.

120/240 VAC 1Ø
120/208 VAC 3Ø
277/480 VAC 3Ø

Voltage ranges are selected by rotating the handle on the
switch to the desired voltage. The switch is equipped with
a locking mechanism. This allows the voltage setting to
be locked in place to prevent unauthorized personnel
from changing the voltage selection. To lock switch in
position, push lock up and attach a padlock through the
openings in the locking strip.

CAUTION: NEVER CHANGE THE VOLTAGE SELEC-

TOR SWITCH WITH THE ENGINE RUNNING. This can
cause arcing and can severely damage the switch and
the generator windings.

1.15 Emergency Stop Switch

The emergency stop switch is the red button located to
the left of the control panel and can be accessed with the
panel doors closed.

Close the emergency stop switch by pushing the red
button in. Closing the emergency stop switch opens the
main circuit breaker and the fuel solenoid and results in
the engine shutting down and the red LEDs (g) and (j)
lighting up. The switch will remain closed until the button
is rotated and it pops out.

CAUTION: PRESS THE EMERGENCY STOP BUT-

TON ONLY IN THE CASE OF AN ACTUAL EMER­GENCY WHERE THE GENERATOR MUST BE
STOPPED IMMEDIATELY! In all other instances, open
the main line circuit breaker and then turn the engine start
switch to off “O”.

DANGER

DANGER OF ELECTROCUTION! High voltage is

present inside this panel when the generator is
operating!

1A-18

1.16 Main Line Circuit Breaker

The main line circuit breaker (c) is located on the control
panel.

In the off “O” position, this breaker interrupts power from
the selector switch to the terminal lugs at the bottom of the
generator panel.

CAUTION: Before shutting down the generator or per-

forming any service to the generator unit, make sure the
main circuit breaker is in the off “O” position.

the receptacles are powered even with the main breaker
in the off “O” position. To turn off power to receptacles,
open the individual circuit breakers provided for each.

1.18 Voltage Adjustment Rheostat

Directly below the engine start switch is the voltage
adjustment rheostat (f). Use the rheostat to adjust the AC
voltage output. Turn adjusting screw clockwise to in­crease voltage, counter-clockwise to decrease voltage.
The voltage can be monitored at the LCD panel.

DANGER

DANGER OF ELECTROCUTION! High voltage is

present inside this panel when the generator is
operating!

1.17 Engine Start Switch

The engine start switch (e) is a three-position switch:
“REMOTE START”, off “O”, and “RUN/START”. The
“REMOTE START” position is the normal setting used
when using the generator as a back-up power supply
connected to a remote switch. In the REMOTE START
position the generator is in stand-by mode and will not
start until the remote switch closes. In the “RUN/START”
position the switch immediately initiates the engine start
cycle, pre-heats the engine, then activates the starter
motor to crank the engine.

When set in the “REMOTE START” or “RUN/START”
position this switch applies battery power to the engine
control module to turn on the LCD panel, and also
energizes the engine’s electrical system. In the off “O”
position power to the engine’s electrical system, includ­ing the fuel solenoid, is disconnected.

1.19 Warning Light

The amber warning light (d) on the metering panel will
turn on prior to an engine fault condition occurring. This
acts as a pre-alarm to call attention to a potential fault
condition. At the same time the warning light goes on, the
LCD panel will begin blinking to indicate which engine
function is approaching its fault value.

Engine Pre-alarm Set Points:

• Fuel Level = 25%

• High Temperature = 234° F

• Low Temperature = 70° F

• Low Oil Pressure = 20 psi

• Time to Service = 0 hours

• Sender Failure = engine coolant and oil pressure
senders.

Note:

Time to Service and Sender Failure faults will not

shut down the generator.

1.20 Connection Lugs

The customer connection lugs (a) are located on left at
the bottom of the panel behind a hinged door. The lugs
provide connection points for attachment of outside
loads.

A large label like the one shown in section 1.25

Connections

It shows the correct terminal connections for selected
voltages.

Connections to the lugs should be made by running the
power cables up through the slots (j) in the bottom of the
panel and into the lug. Use a 3/8" Allen wrench to tighten
cable connections in place.

1.21 Ground Connection

A ground connection (b) is located next to the terminal
lugs. The unit must have this ground lug connected to a
good earthen ground for proper operating safety in com­pliance with NEC and local standards.
