Installation Guide
1.Position the slip ring in the desired location and tighten four screws to shaft.
2.Route the wiring and make the necessary connections,fasten the anti-rotation tab.
1.Slip ring can not support the weight of equipment which connects with it, roating equipment should be fastened
so that its weight will not fall on the rotor.
2.Slip ring should be used in dry,low dust environment.If used outdoor,shield is necessary.
3.The surface of lead wire should avoid being damaged while equiment rotating,all lead wire can not bear
weight while you put the lead wire in order.
4.No damaging the surface of lead wire while barking its end.
