Connections
A detailed connection diagram can be found on the following pages.
Before connecting the power supply check the information on the instrument label!
Warning
Input, output, and control cables must be installed separate from each other
and especially apart from power lines!
For inputs and outputs use screened cables, and connect the screens on one side only.
The measurements are interference-sensitive. Use only our special cables with a very high insulation
for short distances, and for longer distances an impedance converter.
For the connection of temperature sensors use a low-resistance cable with a large diameter.
When using the relays, mind that with inductive loads, interference must be suppressed. If that is not
possible, the relay must be protected at the terminal block by a resistance-capacity filter or, in case of
direct current, by a free-wheeling diode.
