2.7 Grounding / Earthing
The ESML6-P3 has an earth point located on the top panel of the switch. To achieve
the best earth connection, a circular cold-press terminal should be crimped to one
end of the earth wire and attached to the unit with the screw, making sure that the
star washer stays in contact with the body of the switch. The cross-section of
grounding wire should not be less than 2.5mm
