in safe and perfect condition. To maintain this condition
the operator has to respect the safety measures contained
in this instruction manual.
In order to avoid electrical shock: The safety meas-
ures have to be respected when working with volt-
ages exceeding 75 V (60 V) DC or 50 V (25 V)rms
AC. According to DIN VDE these voltages represent
the threshold contact voltages . Please note: The val-
ues indicated in brackets are valid for limited ranges
such as in hospitals or on farms.
