(2) Ground jack
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 (3)
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 (4) 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 correspondence 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.
(6) L1/N selector switch
Provided that the HM605-2 is correctly connected to the mains power
outlet (point (4)) LED (5) is lit after power-on. The EMC signal immediately
will be available at output jack "Test Receiver" (11). By pushing button
(6) the signal source toggles to line N, which is indicated by a LED (7) lit.
