5 Connection to Circuits
Fehler! AutoText-Eintrag nicht definiert.
Danger! Risk of electrocution!
By connecting the unit to circuits, the terminals and certain
parts inside the device are live.
In order to ensure safe operation, first connect the device to the
power supply.
If possible, open the circuit before establishing a connection to
the analyzer.
Prior to connecting the circuits, ensure that the maximum
measuring voltage and max. voltage to earth (1000V CATII and
600V CATIII respectively) are not exceeded.
Do not use leads and accessories that do not fulfil the relevant
safety standards, as this could lead to serious injury or death
from electric shock!
5.1 Connecting sequence
When connecting a circuit to the power analyzer, for safety
reasons, proceed in the sequence outlined below:
1. Connect the power analyzer to the mains socket.
The analyzer is now connected to the protective earth wire.
2. Switch on the power analyzer.
3. Connect the measuring circuit as shown in the connection
diagram.
Ensure that the phase is connected to HI so that the energy
flow is from HI to LO; to ensure that the measured values are
indicated correctly.
4. Connect the circuit to the power supply.
5.2 Overview
The power analyzer offers the following options for connection:
Measurement direct with shunt with
transducer
1-phase
measurement

3-phase
measurement in 4-
wire system
page 19 page 20 -
Note
When connecting a 4-channel device for electrical efficiency
analysis, the 3-phase power cables for this measurement should be
connected to the measuring channels 1 to 3, so that the efficiency
can be calculated and displayed directly on the device.
