4.4.5Grounding

CAUTION

Be sure to connect the protective grounding of the AXFA11 with a cable of 2mm2 or larger cross section in oder to avoid electrical shock to the operators and maintenance engineers and to prevent the influence of external noise. Connect the grounding wire to the mark (100  or less).

IMPORTANT

When optional code A (lighting protector) is selected, the ground should satisfy Class C requirements (grounding resistance, 10  or less).

•The protective grounding terminals are located on the inside and outside of the terminal area.

Either terminal may be used.

•Use 600 V vinyl insulation wires as the grounding wires.
