APPENDIX 1 - 3
WARNING
Electric shock due to improper grounding!
This instrument is designed in conformity with the
specifications of Class I in Annex H of the IEC 61010-1
(International Electrotechnical Commission Standards) -
Issue 1. To prevent an electric shock hazard, provide a
proper grounding connection.
(a) Be sure to use the grounded 3P power cable which is
supplied as a standard accessory for the instrument.
The use of a different type of power cable may result
in an electric shock hazard. Connect the 3P power
cable to a grounded 3P power outlet.
(b) If a grounded 3P power outlet is not available, use a
grounded 3P table tap or a 3P-to-2P adapter. In this
case, be sure to provide a proper grounding
connection. For grounding connection, use a screw
having a diameter of M4 or higher and a turn count of
3 or more in threading, and a wire having a thickness
of 1.25 mm.
(2) Ground Terminal
Shall have a grounding construction for a ground resistance
of 100
or less.
