WARNING! The HFG02 must be earthed.
Any interruption of the mains earth conductor inside or outside the HFG02 case
may make the instrument electrically dangerous. If the Test Supply does not
present an earth connection to the Test Supply Cable, then the external earth
connector on the front of the HFG02 must be connected to a safety earth.
The HFG02 is classified as IEC Safety Class 1. It has been designed to meet the
requirements of EN/IEC/UL 61010, Safety requirements for Electrical Equipment
for Measurement, Control and Laboratory Use.
The HFG02 has been tested in accordance with EN/IEC/UL 61010 and has been
supplied in a safe condition. This instruction manual contains information and
warnings that have to be followed by the user to ensure safe operation and to retain
the instrument in a safe condition.
The HFG02 has been designed for indoor use only in a Pollution Degree 2
environment within the temperature range 5

Humidity (non- condensing). Do not operate whilst condensation is present.
Use of the HFG02 in a manner not specified by these instructions may impair the
safety protection provided. Do not use the HFG02 outside its rated supply voltage
or environmental ranges.
The HFG02 must be positioned in a way that allows full access to any on/off switch
on the Test Supply or Mains Supply.
Ensure that fuses with the required rated current and specified type are used for
replacement. The use of makeshift fuses and the short-circuiting of fuse holders is
dangerous and must be prohibited.
The mains cord included with the Power Supply Unit must only be replaced with
an adequately-rated cord
If the HFG02 is clearly defective, has been subject to mechanical damage,
excessive moisture or chemical corrosion the safety protection may be impaired.
