Wanco Two-Bearing Belt-Drive Generators
1 Introduction
1.1 Read before using
This is an industrial-type electric generator. This equipment is
potentially hazardous and could cause physical injury or even death
if improperly used. Before attempting to operate this generator:
■Check to ensure no damage has occurred in transit
■Read this manual thoroughly
■Follow all instructions carefully
■Before using an engine to power the generator, read the engine
manufacturer’s instructions
By following these instructions, you will enjoy safe and trouble-free
operation of your generator.
Installing and wiring a home standby generator is not a do-it-
yourself project. Consult a qualified licensed electrician or
contractor.
WARNING
Improper use of equipment could cause
serious injury or death.
Prior to using this equipment, carefully read,
understand, and observe all instructions.

1.2 Principle of operation
1.2.1 AB- and AR-Series
On AB- and AR-Series generators, the generator stator and the main
phase output winding have an auxiliary phase winding that is
connected to a capacitor.
The resultant current flow creates an alternating armature reaction
that can be considered the combination of two rotating fields. One
field is in the direction of the generator rotation at the same speed;
the other is in the opposite direction, and induces in the rotor field
winding an electromagnetic field that is double the rated
frequency.
By connecting a diode in series with the rotor field winding, the
current is rectified and the necessary excitation is obtained.
The voltage regulation at load is ensured by the field build-up
generated by the armature reactance and the rotating field
windings.
1.2.2 EC-Series
All EC-Series generators are 12-wire brushless generators with an
exciter generator that induces a voltage in the main generator. An
automatic voltage regulator is connected to the main generator
and controls the output voltage of the generator.
EC-Series generators are 3-phase wound generators that are
reconnected for single-phase applications. They can operate at 60
hertz and 1800 RPM or 50 hertz and 1500 RPM with reconnections.
All EC-Series generators can operate in bidirectional rotation
(clockwise or counterclockwise). They can function as prime power
with 24-hour continuous operation.

2 Safety
2.1 Operating safety
DANGER
Explosion hazard.
■NEVER operate generator in an explosive
atmosphere or near combustible materials.
■Keep generator, engine, fuel, and other
combustibles away from sparks, open flame,
and burning objects.
■Before using an engine to power the generator,
read engine manufacturer’s instructions.
6 Owner’s Manual
Wanco Two-Bearing Belt-Drive Generators
■Before using this equipment, carefully read, understand, and
observe all instructions in this manual.
■If using an engine to power the generator, read the engine
manufacturer’s instructions.
■Before using this equipment for the first time, inspect it for loose or
missing parts and damage that may have occurred in shipment.
■This equipment should not be operated by persons under 18 years
of age.
■ALWAYS wear appropriate protective clothing, shoes, and other
protective devices, as required by the job.
■When working on or around this equipment, do not wear neckties,
loose-fitting shirts or jackets, or sleeves that may become caught in
moving parts.
■ALWAYS wear appropriate respiratory, hearing, and eye protection.
■NEVER operate this equipment when not feeling well due to fatigue,
illness, or medication.
WARNING
Shock hazard.
■Use extreme caution when working on or with
electrical components.
■Avoid contact with live terminals and
receptacles.
■The generator must be properly grounded
according to all applicable electrical codes.
■Do not operate generator in rain, snow, or wet
conditions.
■Use only 3-prong grounded receptacles and
extension cords.
■On construction sites, use a GFCI (ground fault
circuit interrupter) to protect 120-volt
receptacles.
■Installation as a standby generator must
comply with all applicable electrical codes, and
requires a suitable power-transfer device to
isolate generator from power utility.
