Setting into operation

Read the operator's manual before
setting up the HM6050-2!
To put the HM6050-2 into operation it
has to be connected to an AC power
outlet (with protective ground) accor-
ding to VDE-0100. Due to the relative
high leakage current (ca. 800 mA) the
equipment cannot be operated in com-
bination with a leakage current circuit
breaker. Thus, "protective ground" is
equivalent to"earth". Any interruption
of the protective ground conductor
inside or outside the instrument is
prohibited.
Only qualified personnel are allowed to set up
the LISN into operation. The HM6050-2 has been
designed in conformity to regulations VDE 9876
and CISPR Publ. 16. The leakage current of the
instrument exceeds the allowed value of 0.5 mA
as defined in IEC 348 and VDE 411 for normally
operating measurement instruments. Thus, the
safety requirements have to be accomplished by
additional provisions according to IEC364-4-41
(CENELEC HD 384.4.41 and VDE 0100 Part410).
Due to the circuitry of the HM6050-2 a maximum
leakage currentof 800 mA can occur. It is not pos-
sible to operate the HM6050-2 at a mains outlet
with a leakage current circuit breaker.
Attention! Danger of death!
The LISN has to be grounded accor-
ding to the regulations (Cenelec
HD384/DIN VDE0100) separately;
otherwise conductive parts of the-
housing, which may be touched by the
user, lie on a dangerous high voltage
level.

1 Artificial Hand
This feature simulates the influence of the
human hand. When performing EMC mea-
surements for devices, which are held in hand
during use (for example: electrical drilling
machines, hairdryer etc.) the Artificial Hand
simulates the influence of the human hand on
the EMC behavior of the equipment.
If the DUT has a plastic housing, a conductive
film should be used to cover the housing
at the location, where it is held in hand. A
test lead is used to connect the film to ba-
nana jack 1. DUTs with a metal housing are
connected directly to banana jack 1, if they
don't have a protective ground connection
according to Class 1.
2 Ground jack
eff
This jack is used for testing DUTs, which
don't have a protective ground line in their AC
power cable, but do have a separate ground
connection. The DUT's ground connector has
to be linked to banana jack 2 via a test lead.
This lead should be placed in parallel to the
two-line AC power cable.
3 Mains power outlet for the DUT
The DUT will be connected to the HM6050-
2's Mains power outlet with its AC power
cable. The maximum supply current of the
DUT must not exceed a continuous current
of 16 A at an ambient temperature of 23°C. At
higher ambient temperatures a fan has to be
used for cooling. In any case a sufficient free
air circulation has to be kept for the HM6050-
2.
4 LeD L1
If the mains plug connected in correctly in
phase, LED L1 is lit. If it does not, the mains
plug has to be turned by 180°. There is no risk
related to the phase status, but the corre-
spondence to the indication for L1 (line) and
N (neutral) might be incorrect. In case an
asymmetric mains plug is used, lines L1 and
N have to be changed inside the plug of the
power cable.
