reactive current at the IN input.
For low frequencies below 1 kHz, the input impedance is in the < 100 mΩ range. For high frequencies
above 10 kHz, the termination impedance is equivalent to the termination impedance of 50 Ω connected
to the PD output of CPL1. Special versions of CPL1 for NEMA and CISPR measurements feature an
input impedance of 150 Ω or 300 Ω respectively.

The GND wing nut is connected to the ground with a short connection.
► Do not ground the MPD 800 acquisition unit or its accessories in this case.
DANGER
Death or severe injury caused by high voltage or current
A failure inside CPL1 may result in residual charges at the coupling capacitor or test
object, 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 CPL1 into a system.
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
CPL1 is not intended to be used for measurements which are connected directly to
mains circuits (IEC61010-2-030).
► Make sure to connect CPL1 to the test setup using appropriate rated accessories
because CPL1 is not able to handle power frequency fault currents.
