6.2.2 Power Supply

For trouble-free operation use a separate power supply for the LLB.
● LLB: 9...30 VDC, 0.5 A
● LLB (H): 24...30 VDC, 2.5 A

6.2.3 Cable connection

A ferrite core must be fitted to the connecting cable. Use a ferrite core with an impedance of 150 Ω up
to 260 Ω at 25 MHz and 640 Ω up to 730 Ω at 100 MHz. For example you can use KCF-65 from KE
Kitagawa.

6.2.4 Shield and Ground

The LLB measuring system contains two electrically isolated grounds, the general ground (GND) and
the analog ground (AGND). GND and AGND are connected to the housing by a RC element. Please
see Figure 14.
