Electrical Connections - Eliwell DR4000 series Handbuch

Important! Make sure the machine is switched off before working on the electrical
connections.
The instrument is equipped with screw-type or plug-in terminal boards for connection of wires
having a maximum cross section of 2.5 mm
feeding connections): refer to the label on the instrument for details of the terminal ratings. Do
not exceed the maximum permitted current; for higher loads, use a contactor with sufficient
power capacity.
Make sure that the power supply is of the correct voltage for the device. Probes have no
connection polarity and can be extended using a normal two-core cable (note that extension
of the probe leads influences the instrument's electromagnetic compatibility EMC: take great
care with the wiring). Probe cables, power supply cables and the TTL serial cable should be
routed separately from the mains power cables.
