6.1 Safety
WARNING!
Risk of injury due to electric shock.
• For the electrical power supply, use only PELV circuits in accordance with IEC
60204-1/EN 60204-1 (Protective Extra-Low Voltage, PELV).
• Observe the general requirements of IEC 60204-1/EN60204-1 for PELV cir-
cuits.
• Only use voltage sources that ensure a reliable electric separation from the
mains network in accordance with IEC 60204-1/EN 60204-1.
NOTICE!
Malfunction due to electromagnetic interference.
Incorrect measuring results and incorrectly stated positions.
• Use permitted lines without extensions.
• Lay permitted lines with sufficient clearance from lines with high noise level.
• Connect the earth terminal with low impedance to the earth potential.
