3.1.3 Inputs and outputs on both versions
Caution!
Risk of electric shock.
External control circuits connected to the instrument must have Class II
insulation.
Note:
All capacitors must be of VDE standard class (class x2) and capable of withstanding a voltage of at least
230 V AC. The maximum power dissipation capacity of the resistor must equal at least 2 W.
Note:
The company of burster präzisionsmesstechnik gmbH & co kg does not accept liability under any
circumstances for personal injury or property damage resulting from unauthorized access, improper use
or inappropriate operation or use given the technical properties of the unit, or from use that contravenes
the instructions given in the present operating manual.
Follow these instructions when connecting the unit:
¾
Arrange the input leads separately from the leads for the power supply, and from the outputs and
main power lines.
¾
Use twisted/screened cable with its shield grounded at least at one end.
¾
For output lines that are switched under load (contactor, solenoid valves, motors, fans etc.),
connect an RC element (resistor and capacitor in series) in parallel with the load.
This will suppress interference emissions.
¾
For an inductive load, connect a type 1N4007 diode in parallel with the load.
