EXTERNAL OR INTERNAL OPERATING ENERGY SOURCE. THIS DISCONNECTING
MEANS SHALL DISCONNECT ALL CURRENT CARRYING CONDUCTORS.
WARNING: DO NOT TOP LOAD
WARNING: IN ORDER TO PREVENT RISK OF ELECTRIC SHOCK OR FIRE
HAZARD DUE TO OVERHEATING, ENSURE THAT THE UNIT’S VENTILATION
OPENINGS ARE NOT OBSTRUCTED.
2.1.3 Grounding
This product is a Safety Class 1 instrument. To minimize shock hazard, the instrument
chassis must be connected to an electrical ground. The instrument must be connected to
the AC power supply mains through a three conductor power cable, with the ground wire
firmly connected to an electrical ground (safety ground) at the power outlet.
For instruments designed to be hard-wired to the supply mains, the protective earth
terminal must be connected to the safety electrical ground before another connection is
made. Any interruption of the protective ground conductor or disconnection of the
protective earth terminal will cause a potential shock hazard that might cause personal
injury.
WARNING: DUE TO THE HIGH LEAKAGE CURRENT, REMEMBER TO
CONNECT ALSO THE CHASSIS EARTH TERMINAL (SEE §1.7) TO A GOOD EARTH
WITH A LOW IMPEDANCE CABLE PATH, IN ORDER TO IMPROVE SAFETY; SUCH
TERMINAL IS IN ITS TURN INTERNALLY CONNECTED TO PROTECTION EARTH.
2.1.4 Input
ratings
Do not use AC supply, which exceeds the input voltage and frequency rating of this
instrument. For input voltage and frequency rating of the module see § 1.4. For safety
reasons, the mains supply voltage fluctuations should not exceed above voltage range.
