5. Voltage measurement
5.1 Overview material for voltage measurement
Fig. 5.1: Overview material for voltage measurement
From left to right: secured measuring voltage cables, crocodile clips, safety crocodile clips,
magnetic test probes
Connect the measuring voltage cable to the corresponding socket L1…3/N/PE at the
side of the case.
To connect the secured side of the measuring voltage cable you have the following op-
tions:
 
Crocodile clips (PE always, for other cables optional)
 
Safety crocodile clips for use with push-wire terminals
 
Magnetic test probes to enable the screws to make contact with the circuit
breaker
Risk of fatal injury from electric shock!
First
connect the laboratory plugs to the case .
Only after this step the measuring voltage cables may be connected to the
system.
Risk of fatal injury from electric shock!
Incorrect wiring of the measuring voltage cables may cause a short-circuit
of the installation, arcs and high short-circuit currents.
Never use measuring cables without integrated fuse for voltage
coupling!
The side of the measuring voltage cable with the fuse (longer plug)
must be connected to the installation .
