GROUNDING THE GENERATOR
y
In terms of protection against dangerous contact voltage
on non-live parts, the generator meets the requirements 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 electrical
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 APPLIANCES
TO THE GENERATOR
y
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.
y
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 con-
ductor cross-section of 1.5 mm
2
(for a nominal current in the
range > 10 A to ≤ 16 A) must not exceed 60 m. With a con-
ductor cross-section of 2.5 mm
2
(for a nominal current in the
range > 16 A to ≤ 25 A) the length of the cable must not exce-
ed 100 m (with the exception of cases, where the generator
meets the requirements of protection 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 len-
gth of a flexible extension cable with a wire cross-section of
1.0 mm
2
Cu at a nominal current of 10 A (2.3 kW) must not
be longer than 10 m, an extension cable with a core cross-
-section of 1.5 mm
2
Cu at a nominal current of 16 A (3.68 kW)
must then be no longer than 50 m. According to this norm,
the total length of a flexible power cable including extensi-
on cords should not exceed 50 m (if, for example, this is an
extension cord with a cross-section of 2.5 mm
2
Cu).
y
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.
DRAWING DIRECT CURRENT
(DC 12 V, 8.3 A)
y
The 12 V/8.3 A DC power socket (see description of the
control panel) is intended for recharging 12 V lead car
batteries with a capacity of at least 70 Ah with the use of
12 V charging cables with crocodile clips.
1. Turn off the motor vehicle, turn off all turned on
electrical devices inside the vehicle and take the
key out of the vehicle's ignition and turn off the
generator if it is running.
2. Insert the charging cables into the 12 V DC socket
on the generator.
•
ATTENTION
y
Only connect the 12 V DC charging output of the
generator to the car battery when the generator is
not running.
3. Before connecting the charging cables to the car
battery terminals, first identify which battery ter-
minal is grounded, i.e. connected to the chassis
(frame) of the vehicle.
On most modern vehicles the grounded negative
electrode of the car battery is marked with the sym-
bol "–". In this case, first connect the alligator clip
with the red charging cable to the non-grounded
positive pole of the battery ("+") and then connect
the alligator clip of the black charging cable ("–") to
the chassis (frame) of the vehicle. Do not connect
the alligator clip to the carburettor, fuel line or
sheet metal parts of the chassis, always use massive
solid metal parts of the frame or the engine block.
y
In the event that the positive electrode of the car
battery is grounded, then first connect the black
charging cable with the alligator clip ("–") to the
negative electrode of the car battery and then con-
nect the alligator clip with the red charging cable
("+") to the chassis (frame) of the vehicle, whilst adhe-
ring to all the measures described above.
y
Take care that the charging cables are correctly
connected to the terminals of the car battery.
Connect the clamp of the red cable to the positi-
ve terminal and the clamp of the black cable to
the negative terminal of the car battery.
4. Start the engine of the generator.
y
When charging batteries, follow the instructions of
the battery's manufacturer.
y
Do not start the engine of the motor vehicle during
the recharging process.
y
In the event that these instructions are not followed,
the generator and car battery may be damaged
