GROUNDING THE GENERATOR

y In terms of protection against dangerous contact vol-
tage on non-live parts, the generator meets the requi-
rements of the currently valid European Directive HD
HD 60364-4-4 for protection by electrical isolation. The
requirements of this directive are entered into national
electro-technical norms of the given country (in the
Czech Republic this is norm ČSN 33 2000-4-41 including
valid annexes, if they exist).
y Norm EN ISO 8528-13, which specifies safety require-
ments for generators, requires that the user's manual of
the generator includes the information that the genera-
tor does not need to be grounded in the case where the
generator meets the aforementioned requirements for
protection by electrical isolation.
y The grounding terminal with which the generator is
equipped is used for unifying the protection between
the circuits of the generator and the connected electri-
cal device in the case where the connected electrical
device has Class I. protection or the electrical device is
grounded, where it is then also necessary to ground the
generator for the requirements of directive HD 60364-
4- 4 (in the Czech Republic it is norm ČSN 33 2000- 4- 41)
to be met. Grounding must be performed using norm
compliant grounding devices and must be carried out
by a person with the required professional qualifications
based on the conditions where the generator is located
and operated.
USING AN EXTENSION CORD
FOR CONNECTING ELECTRICAL
DEVICES TO THE GENERATOR
 The load capacity of the cables depends on the
resistance of the conductor. The longer the cable used,
the greater must be the cross-section of the conductor
(wire/s). Due to electrical power losses, the greater the
length of a cable, generally the lower is the operating
performance at its end.
 According to norm EN ISO 8528- 13, when using
extension cords or mobile distribution networks, the
resistance value must not exceed 1.5 Ω. The total
length of cables with a conductor cross-section of
2
1.5 mm (for a nominal current in the range > 10 A
to ≤ 16 A) must not exceed 60 m. With a conductor
cross-section of 2.5 mm
range > 16 A to ≤ 25 A) the length of the cable must
not exceed 100 m (with the exception of cases, where
the generator meets the requirements of protecti-
on by electrical isolation in accordance with annex
B (B.5.2.1.1.) of norm EN ISO 8528- 13.
According to the Czech norm ČSN 340350, the nominal
length of a flexible extension cable with a wire cross-
2
-section of 1.0 mm Cu at a nominal current of 10 A (2.3
kW) must not be longer than 10 m, an extension cable

(for a nominal current in the
with a core cross-section of 1.5 mm
current of 16 A (3.68 kW) must then be no longer than
50 m. According to this norm, the total length of a fle-
xible power cable including extension cords should
not exceed 50 m (if, for example, this is an extension
cord with a cross-section of 2.5 mm
 For reasons of cooling, the extension cord must not be
wound up or wound on to a spool, but must be fully
unwound along its entire length in order to be cooled
by the temperature of the ambient environment.
OPERATION AT HIGH
ABOVE SEA LEVEL ALTITUDES
y At a higher above sea level altitude (above 1,500
m a.s.l.) the fuel:air ratio changes in the carburettor
towards flooding with fuel (insufficient amount of
air). This results in a loss of performance, increased
fuel consumption, carbonisation of the engine,
exhaust pipe, spark plug and more difficult starting.
Operation at high above sea level altitudes also
negatively affects exhaust fume emissions.
y In the event that you wish to operate the generator at
an altitude greater than 1,500 metres above sea level for
an extended period of time, have the carburettor read-
justed at an authorised service centre for the HERON®
brand.
Do not adjust the carburettor yourself!
•
ATTENTION
y Even with the recommended readjustment of the
generator's carburettor, the performance nevertheless
declines by about 3.5 % per every 305 m of above sea
level altitude. Without performing the above-described
readjustments, the loss in performance is even greater.
y When the generator is operated at an above sea level
altitude that is lower than for which the carburettor
is set, the carburettor has a lower fuel mixture, which
again results in a loss in performance. Therefore, it is
necessary to readjust the carburettor.
IX. Care and maintenance
1. Before commencing maintenance tasks, turn off
the engine and position it generator on a rigid
horizontal surface.
2. Allow the generator to cool down before perfor-
ming maintenance (servicing) tasks.
•
ATTENTION
y Only original spare parts of the manufacturer may
be used for repairs of the generator.
 Regular inspections, maintenance, checks, audits and
adjustments in regular intervals are an essential pre-
requisite for ensuring safety and for achieving high
performance of the generator. Table 5 provides the
plan of tasks that must be performed in regular inter-
