11.4 Operating the generator
(Working safely with electrical
equipment)
This state-of-the-art synchronous
generator has been designed and built
with maximum safety in mind. It will help
you get the most out of your work or leisure
activities. However, like all electrical
equipment, it can represent a source of
danger (e.g. risk of electric shock) if the
operating instructions in this section are not
followed exactly. Please observe the
instructions and the notes on dangers
affixed to your generator.
Before starting the generator, all devices
must be unplugged and switched off. Only
plug the devices in (one after the other)
and switch them on after the engine driving
the generator has reached its nominal
operating speed.
Keep the glass cover over the circuit
breaker on the front panel closed at all
times. Tighten the knurled screws by hand
to maintain IP protection.
Do not open the generator or the
switchbox. The brushless synchronous
design does not require maintenance.
Do not modify the internal wiring.
Repairs to electrical components and to
electrical operating equipment (supply
cables, loads) may only be carried out by
suitably trained electricians.
The circuit breakers, control, alarm and
release devices and the insulation monitors
are specially designed for the generator
and its sockets. Only use original spare
parts if replacements are needed.
The generator meets the requirements of
the Protective isolation with equipotential
bonding conductor and insulation
monitoring with circuit breakers regulation
in DIN/VDE 0100 Part 728 §4.2.4.2.1 and
the German Gas Installation and Plumbing
Association (DVGW) regulation GW 308.
The system is an IT type, with neutral and
PE (equipotential bonding conductor).
The generator does not have to be
earthed (with a ground rod for example) to
ensure adequate safety protection.
However, if desired or required, defined
earthing of the generator can also be
provided.
Earthing of the neutral (N), or connecting
of the neutral to the equipotential bonding
conductor (PE), is prohibited on the
generator, the distribution system and all
other devices. The use of so-called
neutralised devices is not permitted, and
would lead to insulation monitoring being
enabled automatically.
The generator must not be used to inject
power into a construction site distribution
system.
To avoid unwanted interaction, do not
connect distribution systems with additional
insulation monitors to the generator with its
built-in equivalent.
During insulation and voltage tests
carried out on the generator by trained
electricians, disconnect the insulation
monitor.
Because the generator is not earthed,
fault current circuit breakers used in
distribution systems and equipment cannot
be relied upon to operate correctly when
such units are connected to the generator,
and, due to the Electrical isolation with
insulation monitoring and circuit breaking
protective measure, are not actually
required.
The insulation monitor and circuit breaker
should be checked daily when the
generator is in use, following the quick
reference instructions for Testing/insulation
monitoring/starting/connecting equipment
which are affixed to the generator.
Attention
Devices connected the generator which
cause the circuit breaker to release, and
the red indicator lamp for Insulation
fault to light up, must not be connected
to other generators (without insulation
monitoring), or to the public mains.
Have equipment with insulation faults
immediately replaced or repaired by the
manufacturer or a suitable electrical
specialist.
When working in restricted conductive
areas, i.e. as defined in DIN/VDE 0100 706
(e.g. in boilers), only one power tool or
mobile measuring instrument may
be connected to the generator, or for
each such load an additional isolating
transformer, or one isolating transformer
with several secondary windings, should
be used. Handheld lights may only ever
be used in restricted conductive areas
when operated off a SELV (safe extra low
voltage) isolating transformer.
Many portable power tools conform to
German protection class II (i.e. they are
double insulated, symbol ■■
■■
). These
devices should be used if possible. Use a
cable and plug to connect any protection
class I device (i.e. with metal housing parts
that are not double insulated) to be used to
the PE (equipotential bonding) conductor.
Only connect devices and distribution
systems which are in good condition to the
generator. The insulation, and plug and
socket combinations, must be in good
condition to ensure user safety. Do not use
any damp or dirty connectors.
The distribution systems (e.g. extension
cables, device leads) must be carefully
chosen, laid and maintained. Check the
electrical cables regularly, replacing rather
than repairing any that are faulty.
To cope with the greater mechanical
strains and stresses on the generator’s
distribution system, use rubber-sheathed
cables to the minimum standard of
H07RN-F or A07RN-F in accordance with
DIN/VDE 0282 Part 810, or equivalent
designs, as moveable (extension) cables.
Where the cables may be under severe
stress, lay them in mechanical protection
systems, or with strong covers, or
use NSSHöü cables in accordance with
VDE 0250.
The lengths and conductor cross sections
of the extension cables must match the
type of equipment and the duty.
It is essential to ensure supply cables do
not exceed the maximum lengths specified!
When using extension cables or moveable
distribution systems, the sum of the lengths
of all extension cables connected to a
generator must not exceed 250 metres
(for a copper conductor cross section of
2.5 mm
2
- for all sockets). The total length
of the extension cable, or the moveable
distribution system, connected to any
particular socket must not exceed 60 m
for a copper conductor cross section of
1.5 mm
2
, or 100 metres for one of 2.5 mm
2
.
Note
For defined releasing of the circuit breaker,
a loop resistance of 1.5
Ω
per socket must
not be exceeded.
The circuit breaker must not be used for
routine switching on of the 3-phase
generator. If several devices, particularly
those with different power consumption
levels, are connected to the AC sockets,
different voltage drops can arise,
depending on the turn-on time of the
neutral.
Avoid overloading the generator. In
particular, to ensure user safety and
optimum performance, it is essential to
observe the following rules:
1. Only devices whose voltage and
frequency data on the load identification
plate conform to those on the generator
identification plate may be connected.
2. Only devices whose power consumption
does not exceed the output specified on
the generator identification plate may be
used. The total power consumption of all
of the loads connected to the generator
must not exceed its output.
