6.3 Insulation Resistance RINS in compliance with
EN 60204 / IEC 60204
Measurement Function 5
The UUT/machinery must be disconnected from the
mains during the insulation test, and it must be ensured that all loads of the machinery under test are
switched on. Failure to respect these references can
lead to instrument damage.
The UUT/the machinery under test may not be
touched during the measurement, danger of electrical shock!
Insulation measurement causes charging of capacitive UUTs. Upon termination of measurement, the
UNITEST MACHINEmaster automatically discharges UUT. When interrupting the measurement,
a dangerous voltage may remain at UUT. If a dangerous voltage has been detected by means of
measurement function 3 (V/f), the UUT has to be discharged by using a high-ohm resistance (not via
short-circuit!).
How to carry out the measurement ?
The measurement may only be carried out by using COMMANDER 2.
STEP 1

General Information for Performing Appliance
Tests in Compliance with DIN VDE 0701/0702
The accident prevention prescriptions regarding electrical systems and equipment of the "Berufsgenossenschaft" [German employer’s liability insurance association] defines the time frame for testing electrical
instruments:
• Prior to first initial use as well as after modification,
maintenance and prior to re-operation as well as in defined TIME INTERVALS.
• For portable appliances this TIME INTERVAL generally amounts to 6 months (3 months for building sites).
Depending on the intensity of use, the time interval
should be kept flexible, provided that the instrument safety is always ensured. The maintenance interval for building sites can be extended to maximum 12 months, for indoor use to maximum 24 months.
The DIN VDE regulation of the DIN VDE 0701 and DIN VDE
0701/0702 range defines test sequence and limit values.
7.1
Explanation of Technical Terms
Leakage Current:
The leakage current is defined as the current flowing from
a UUT via the insulation. This can be either via the casing, or via touchable and conductible parts, or via the PE,
or via additional earth connections (e.g. antenna connection, water connection) of a UUT.
Touching Current:
A current measurement of touchable and conductible
parts of a UUT towards earth, limit value in compliance
with DIN VDE 0701/0702 is 0.5 mA. The measurement
can be carried out either directly or in compliance with
the differential current procedure.
The contact current measurement is carried out for instruments of protection class II equipped with touchable
and conductible parts, or for instruments of protection
class I equipped with touchable and conductible parts not
being connected to the PE. The measurement must be
carried out for both mains plug positions, in case the
mains plug is reversable.
Differential Current:
According to DIN VDE 0701/0702, this is a measurement
procedure to determine the protective conductor or the
contact current. This is determined by a cumulative current measurement including all active conductors (L1L2-L3-N) of a UUT. With this procedure, the total UUT
leakage current can be measured. The measurement
must be applied if the UUT is equipped with an additional earth connection or cannot be installed instead from
earth. This measurement procedure is used for the
UNITEST MACHINEmaster.
Substitute Leakage Current:
According to DIN VDE 0701 it is an alternative measurement procedure to determine the protective conductor or
contact current. In accordance with DIN VDE 0702, this
measurement is considered as a substitute for insulation
measurement. It can be applied if instruments equipped
with heating elements of protection class I do not meet
the insulation values requested. This measurement procedure determines the leakage current being deviated via
the protective conductor or a touchable part without including the mains voltage.
Insulation Measurement:
A measurement of the insulation resistance between active parts (L1-L2-L3-N) and the protective earth conductor (PE) within a system, an instrument or a machinery.
Here, a test voltage of 500 V DC is used in compliance
with DIN VDE 0701/0702.
The limit values differ; please refer to the practical references.
Testing the Presence of Voltage:
Also called leakage current in operation and is determined
by a current measurement for touchable and conductible
UUT parts towards earth in compliance with DIN VDE
0701 Part 240. The limit value according to DIN VDE 0701
Part 240 amounts to 0.25 mA. This measurement is similar to the contact current measurement.
Protection Class I:
Instruments of protection class I are instruments with
basic insulation between active (live) parts and the casing. For structural reasons, the metal casing or metal casing parts must be connected to the protective earth conductor. Instruments belonging to protection class I are
equipped with a shockproof connection mains plug.
Protection Class II:
Instruments of protection class II are equipped with a
continuously reinforced or additional insulation between
the active (live) parts and the casing. However, such instruments may contain touchable, metallic parts. Instruments belonging to protection class II are equipped with
a mains plug without shockproof connection facility.
MACHINEmaster 9050
19
Protection Class III:
Instruments of protection class III are exclusively destined for connecting to SELV [safety extra low voltage]
current circuits, or to circuits being only supplied by an
internal current source with PELV (protective low voltage).
Protective Earth Conductor Current:
This is a part of the UUT leakage current being returned
within the protective earth conductor (PE). The limit value
according to DIN VDE 0701/0702 amounts to 3.5 mA. The
protective earth conductor current is determined either
by a direct current measurement within the UUT protective conductor or by the differential current procedure.
The direct measurement can be applied if the UUT is not
equipped with additional earth connection or can be installed as stand-alone. The measurement has to be carried out for both mains plug positions, in case the mains
plug is reversable. According to DIN VDE 0701:2000-09,
the protective earth current measurement represents an
additional measurement for insulation capacity for instruments belonging to protection class I.
According to DIN VDE 0702, we are dealing with a substitute measurement for insulation measurement for instruments belonging to protection class I for which the
insulation measurement cannot or may not be carried
out.
Protective Earth Conductor Resistance:
This is the protective earth conductor (PE) resistance starting from the mains connection point (earthing contact of
mains plug) to all touchable, metallic UUT casing parts
which should be connected to the protective earth conductor. During the protective conductor measurement, the
connecting line has to be moved across the whole length
in sections. This measurement can only be carried out for
instruments belonging to protection class I.
Visual Inspection:
Emphasis has to be laid on the electrical safety of the instruments parts to ensure that they do not show any damage. The following features have to be considered in particular:
Casing, protective covers
Connection leads and plugs
Condition of insulations
Strain relief, protection against buckling, and conductor
installation
Signs of overload or inappropriate use
Inadmissible interventions or modifications
User accessible fuse holders or fuse inserts
Cooling openings and air filters, Protective covers, Overpressure valves, Fixtures , Contamination or corrosion
presenting security impediments
Labelling for safety reasons

7.1.3
Carrying out Tests in compliance with
DIN VDE 0702 Part 1 (edition 1995-11)
5.) Measurement of the protective conductor current (for
appliances of protection class I)
DIN VDE 0702 defines test procedures and limit values
for repeat tests. The repeat test is defined as a test carried out in determined time intervals with the objective to
prove electrical safety for electrical instruments.
It must be ensured that the protection is effective against
direct or indirect contact. DIN VDE 0702 is valid for electrical instruments, which can be separated from the electrical system by a plug-in device.
The limit value is 3.5 mA

The limit value is 0.5 mA
1.) Visual inspection
2.) PE resistance measurement (for appliances of protection class I)
The limit value is 0.3$ for appliances with connection
leads up to 5m, increased by 0.1$ for every further
7.5m.
This is a substitute measurement to the insulation
measurement for appliances of protection class I.
6.) Measurement of the contact current (for instruments
belonging to protection class II)
This is a substitute measurement to the insulation
measurement for appliances of protection class II, or
for appliances class I with touchable, conductible
parts.
3.) Insulation resistance measurement
The limit value is
0.5M$ for appliances of protection class I
2M$ for appliances of protection class II
0,25M$ for appliances of protection class III
4.) Measurement of the substitute leakage current
The limit value is
7 mA for appliances of protection class I with heating
capacity & 6 k$
15 mA for instruments belonging to protection
class I with heating capacity >6 k$
For appliances of protection class I, equipped with
heating elements for which the insulation resistance
requested is not met, a substitute leakage current
measurement has to be performed.
