The system must be equipotential grounding. Grounded device must meet double requirements of system anti-jamming and
electrical safety, and can’t be short-circuited or hybrid-circuited with neutral leg of forceful electric power. When system
grounded alone, the impedance of grounded conductor can’t more than 4 ohm, and sectional area of grounded wire can’t
more than 25mm2 wire shorted.
Appendix 4 The relationship between Wire and
Distance
When the Wire diameter size is same and the 24VAC power loss below 10%,Recommended Max.transmission distance.( For AC
powered equipment,Max. Power loss is 10% is allowed.For example,One deceive rated power is 80W,Installed 35 feet from the
transformer <10M> distance,it will need the Min.wire size is 0.80mm ).
