Safety rules
*
An electric plant is delivered in a condition corresponding to safety requirements. Do not remove any protection devices. Do not remove any enclosure of electrical equipment. Do not apply unorigi-
nal completing products.
* Waste gases are toxic! Do not use the electric plant in a closed unventilated building.
* Warning! Even if a withdrawing hose for the waste gases of the engine is used, they can get in the building. Therefore, when using in closed buildings, in addition to good ventilation, it is necessary
to follow working normative documents. The withdrawing hose should not be produced from inflammable materials and directed to such materials. Fire danger!
* Be careful working with fuel. Fire and explosion dangers. Do not add fuel to the working plant. Do not pour out fuel on the ground. Use funnel in order to put fuel in.
* Never place the electric plant near inflammable materials. Fire danger!
* Do not touch hot details. Danger of burn!
* Necessarily follow the requirements presented in item 4 «Electric connections and safety measures». Wrong connection represents a danger to life.
* Use protective headphones when staying near the electric plant for a long time.

Design and action principle of the electric plant
1.1 Generator
type
The generator corresponds to the requirements of the VDE 0530 standard. It represents an electric motor with a rotating magnetic system, is short-circuit protective, has self-excitation, is contactless and brus-
hless, and has the block of excitation by alternating current, which consists of electrically strong breakdown-protective film capacitors. The generator has an F class insulation, IP54 protection degree, and
dust- and spray-protection design. The copper windings of the stator have impregnation for moisture and tropic protection. The N VDE 0875 noise level and satisfaction to DIN VDE 0879-1 requirements
are guaranteed.
1.2 Silent Economic
As a rule, the plant should not deliver power continuously. On the contrary, electric power is often necessary urgently by inquiry similarly to the circuits of power-supplying enterprises. By using the Geko-
Silent Economic mode, the rotation frequency of the engine decreases, and it increases sharply after the receipt of an inquiry for the supply of electric power. Thus, the consumption of fuel, emission of
waste gases, noise level, and wear of the engine are essentially reduced. A special electronic processor controls the operating mode of the plant by a measuring system and sensors and operates the engi-
ne. Thus, even when starting the cold engine, the control system is immediately turned on and does not require additional actions. When load is connected, the control system instantly brings the engine to
the rated rotation frequency and total power, which allows the connection of a consumer with high start current.
1.3 General configuration of the plant
The basic components of the electric plant are the engine, generator, distribution box, and bearing frame made of tubes. The generator is connected to the engine by a cone coupling and an additional
threaded pin. The complete „engine-generator“ set is mounted on shock absorbers. Power is taken through three and single-phase ac sockets.
1.4 Voltage
regulation
Regulation of the voltage of the electric plant is strictly set by its design. Voltage is varied within the admissible limits by changing the rotation frequency of the engine. The latter is supplied with an automatic
device, which supports constant rotation frequency (within ±5% limits).
The idle run voltage of the generator is equal to 250 V as a maximum. At the maximum load, it should not fall below 207 V. Warning! Consumers sensitive to the increased and decreased voltage can be
damaged when connecting to the electric plant.
1.5 Standard
complete
set
The electric plant of the standard modification is equipped with a manual starting device (or an electric starter under an order) and CEE sockets or sockets with protective contacts. The complete „engine-
generator“ set is mounted on rubber shock absorbers. All plants have distribution boxes, which contain electric components, sockets, etc.
