ATTENTION!—This symbol alerts you to important operating considerations
or a potential operating condition that could damage equipment. If you see
this marked on equipment, refer to the Operator’s Manual or User’s Manual
for precautionary instructions.
FUNCTIONAL EARTH TERMINAL—A terminal marked with this symbol is elec-
trically connected to a reference point of a measuring circuit or output and is
intended to be earthed for any functional purpose other than safety.
PROTECTIVE EARTH TERMINAL—A terminal marked with this symbol is
bonded to conductive parts of the instrument and is intended to be con-
nected to an external protective earthing system.
It is the equipment operator’s responsibility to provide the cable and select
the appropriate system safety ground. In order to comply with regulatory
requirements, the cable must be 18 AWG or larger and be Green with a Yellow
stripe.
It is the operator’s responsibility to ensure and confirm that the connection
point is suitable and provides a low resistance connection point to ground.
Overall resistance from the Protective Earth terminal to the selected ground
point must be less that 0.1 Ohm.
Typical ground points can be grounded terminals or bare metal on associated
earth-grounded (3-prong connected) equipment or other marked protective
conductor terminals.
