1.1 Safety advice
WARNING!
Connecting terminals carry electrical potential from the
attached sensors/actuators.
Before coming into contact with the connections, ensure
the power is off. Check for any voltages at the connecting
terminals when the attached sensors have varying degrees
of electrical potential or when they have high electrical
potentials with earthing, for example, when measuring elec-
trical current for a mains voltage phase.
Electrical potential differences between different channels
cannot be determined from the measurement data.

Installing modules, memory card or battery
Electronic components are sensitive to ESD ( E lectro- S tatic D ischarge). Therefore,
discharge any electrostatic energy before opening the device, for example to install
an I/O module or to replace the integrated memory card. We recommend wearing
an anti-static wrist band (static discharge wrist band) and to carry out the work on
a conductive surface.
