MPD 800 measurement system
The
IN
input is connected to the bottom end connection of the coupling capacitor or test object.
► Do not exceed 7 A
RMS
reactive current at the
IN
input.
► Do not connect the
IN
input to a voltage source.
For low frequencies below 1 kHz, the input impedance is in the < 100 mΩ range. For high frequencies
above 1 kHz, the termination impedance is equivalent to the termination impedance of 50 Ω connected
to the
PD
output of
CPL2
. Special versions of
CPL2
for NEMA and CISPR measurements transform a
50 Ω impedance connected to the
PD
output to 150 Ω or 300 Ω respectively.
The
RTN/OUT
connector of
CPL2
may be connected to the current input of an additional third party
measuring device. The voltage at this point must not exceed 140V
RMS
respective to the
GND
connector.
The external measuring device must be able to handle the current fed into the
CPL2
IN
input.
DANGER
Death or severe injury caused by high voltage or current
A failure or an open
RTN/OUT
connector of
CPL2
may result in residual charges at the
asset, even with high-voltage side grounded.
► Always observe the five safety rules (see 1.2.2 "Safety rules" on page 6) before
connecting or integrating
CPL2
into a system.
► Short circuit the
RTN/OUT
connector to the
GND
connector if not used.
CAUTION
Minor or moderate injury caused by voltage or current possible
If the ratings are violated, damage or loss of precision of the equipment might be the
consequence.
► Observe the maximum current and power ratings of the measurement input.
► Never connect a voltage source directly to the
IN
input.
WARNING
Death or severe injury caused by high voltage or current possible
CPL2
is not intended to be used for measurements which are connected directly to
mains circuits (IEC61010-2-030).
► Make sure to connect
CPL2
to the test setup using appropriate rated accessories
because
CPL2
is not able to handle power frequency fault currents.
