Precautions.
The sectional area of the grounding cable
(min. of 18AWG) should be selected to safely
conduct the maximum possible current. Use
insulated cables of good conductivity.
• Do not use bare wire.
• The grounding resistance for combined
grounding should be less than 1 Ohm (Ω).
Simple Grounding Steps
• Unfasten the nut on the rear grounding
post of the equipment.
• Affix the terminal of the grounding cable to
the grounding pole.
• Fasten the nut back on the grounding post.
• Connect the other end of the grounding
