14 ac power cable
The power cable is used to attach the HM6050-
2 to the mains outlet. (See: "Setting into ope-
ration").
15 Ground block
The ground block is made of aluminum and
fastened to the backside of the housing by
two screws (below the mains cable outlet).
Terminal "PE" may not be used as reference
ground because it is connected to the PE line
of the mains cable via a filter. If tests are per-
formed outside an EMC chamber only a short
ground cable may be used. Inside a chamber
the ground cable has to be connected between
the ground block and the chamber's shielding
material (VDE 0877, Part1).
16 RS-232 interface
A bi-directional interface is available for re-
mote controlling. A D-Sub connector (9-pin,
female) is located at the back panel of the
LISN; the communication with a computer ac-
cording to the EIA-232 standard is supported.
