1 Introduction
The SPG 5-1000 has been developed for fault locating in low
voltage networks. Its functions are:
DC-Testing,
Breakdown recognition,
Measuring leakage resistance
Prelocating ICEplus,
Pinpoint locating with step voltage or sound field method,
Burning.
No need to use a TDR. ICEplus makes excellent prelocation
possible - even with branched networks. Operation is done
solely with the rotary encoder. For safety reasons the high
voltage setting must be activated with a separate hardware
button.

3 Safety
3.1 General Notes
Safety precautions
This manual contains basic instructions for the
commissioning and operation of the device / system. For this
reason, it is important to ensure that the manual is always
available to the authorised and trained operator. He needs to
read the manual thoroughly. The manufacturer is not liable
for damage to material or humans due to non-observance of
the instructions and safety advices provided by this manual.
Locally applying regulations have to be observed!
Intended application
The operating safety is only guaranteed if the delivered
system is used as intended (see page 1). Incorrect use may
result in danger to the operator, to the system and the
connected equipment.
The thresholds listed in the technical data may not be
exceeded under any circumstances.
Operating staff
The system may only be installed and operated by an
authorised electrician. DIN VDE 0104 (EN 50191), DIN VDE
0105 (EN 50110) and the German accident prevention
regulations (UVV) define an electrician as someone whose
knowledge, experience and familiarity with the applicable
regulations enables him to recognise potential hazards.
Anyone else must be kept away!

Labelling of safety instructions
The following signal words and symbols are used in this
manual and on the product itself:
WARNING
Indicates a potential hazard which may result in
death or serious injury if not avoided.
CAUTION
Indicates a potential hazard which may result in
moderate or minor injury if not avoided.
NOTICE
Indicates a potential hazard which may result in
material damage if not avoided.
Serves to highlight warnings and safety
instructions.
As a warning label on the produc
t it is used to
draw attention to potential hazards which have
to be avoided by reading the manual.
Serves to highlight warnings and safety
instructions that explicitly indicate the risk of an
electric shock.
Using cardiac pacemaker
Physical processes during operation of high voltage may
endanger persons wearing a cardiac pacemaker when near
these high voltage facilities.

WARNING!
Gefahren beim Umgang mit Hochspannung
Working on high voltage systems and equipment – especially
in non-stationary operation – requires particular care and
safety-conscious action on the part of test personnel. VDE
regulations 0104 on setting up and operating electrical test
systems, as well as EN 50191 and national standards and
regulations must be strictly adhered to.
•The SPG 5-1000 generates a dangerous voltage of
up to 5 kV during measurement operation. This is
supplied to the test object via a high-voltage cable.
•The test system may not be operated without
supervision.
•Never fail to use safety equipment or put it out of
operation.
•Operation requires minimum two people whereas the
second person must be able to activate the
emergency switch in case of danger.

3.2 Safety devices
3.2.1 FΩ/ FU-EP protective device
WARNING!
The FΩ / FU-EP protective device is used to monitor the
resistance between the connection points, but not the
connection to earth itself. As described in section 4.3.4, a
good connection to all of the earthing points shown in the
image is an important prerequisite for safe operation. A
potential existing earth connection via the mains power
supply or a single earthing connection via the earth spike is
not sufficient for reliable protective earthing!
Creating a good protective earth connection [ a ] ensures that
the housing and the reference point of the high-voltage output
are on earth potential. The system earth connection [ b ] directs
the normal current that occurs in the test/load circuit.
Illustr. 1 : FΩ/ FU-EP protective device
To ensure that the two connections provide good metallic
contact, the system earth/protective earth loop [ o ] is
monitored by the FΩ protective device (FΩ monitoring).

The resistance between the system and protective earth must
not exceed 6 Ω, otherwise the device will not switch to the
'operational readiness' state. The 'Safety circuit' menu
appears on the display with the message 'FOHM loop
resistance - error'. In some cases, a connection must be
established between the protective earth [ a ] and the system
earth [ b ] to meet this requirement (see chapter 4.3.4).
The connection to the earth spike [ c ] is used as a reference
point for potential monitoring (FU-EP monitoring) and protects
the operator and other individuals from step voltage
potentials. If a dangerous contact voltage (33 V AC / -40 V DC)
or a resistance greater than 150 kΩ is measuredduring
potential monitoring, 'HV stand-by' is either deactivated or
cannot be activated in the first place. The 'Safety circuit' menu
appears on the display with the 'FU-EP' error.c

11
3.2.2 Reverse voltage detection
The SPG 5-1000 is equipped with a reverse voltage
detection, which triggers as soon as the HV connecting cable
is connected to a live (low voltage) cable.
The reverse voltage detection is active only when the device
is in the "stand-by" operating state (green push-button [4] is
illuminated). From operating state "HV-stand-by" (red push-
button [5] is illuminated) on, the reverse voltage detection is
no longer active.
If the reverse voltage detection recognizes an AC voltage
between 40 and 230 VRMS (50 / 60 Hz) at the HV output, the
horn of the SPG 5-1000 sounds. In this case the cable under
test needs to be disconnected from the grid as fast as
possible! Meanwhile, the SPG 5 1000 must not be put in the
“HV stand-by” operating state to prevent damage or
destruction!
3.2.3 Key Switch
For product liability reasons measuring devices emitting
hazardous voltages must be safeguarded against accidental
activation by unauthorised users. For this purpose, the SPG
5-1000 has a key switch which the person in charge has to
keep safe (see page 14, Illustr. 2).

12
3.3 VDE 0104 (EN 50191) clauses
3.3.1 Mobile (non-stationary) test unit
VDE 0104 (EN 50191) standard states that the set-up of the
instrument, including the beginning of the cable to be
measured, represents a non-stationary test installation and is
classed as a test site without protection against touching. The
same also applies to the end(s) of the cable to be tested.
3.3.2 Danger Area
Test sites without necessary contact protection are classed
as ‘danger areas with various zones of danger levels’ and
have to be cordoned off, secured and marked accordingly.
3.3.3 Emergency OFF button
Test sites in general have to be equipped with an emergency
OFF button. The SPG 5-1000 has a red emergency OFF
button on the face plate (see page 14, Illustr. 2). An optional
external emergency OFF button, called ‘external safety
device’, is available. It can be connected to the jack [6] on the
connector panel at the back (see page 15, Illustr. 3 ) When
using the SPG 5-1000 without the external emergency OFF
button, the standard dummy plug has to be placed in jack [6]
so that the device can be switched on.

4 Operating
4.1 Setting up the Instrument
The guidelines for implementation of occupational safety
when operating a test system / test van often differ between
one network operator and another and it is not uncommon for
national regulations (like, i.e. the German BGI 5191) to be
used as well.
Inform yourself of the guidelines applicable in the area of
operation beforehand, and comply with the specified rules for
work organization and for implementing the test system / test
van.
Caution!
DO NOT TRANSPORT OR OPERATE THE SPG 5-1000
WHEN LYING DOWN
because this will lead to safety hazards and damage to the
instrument.
