For all AC connections, 6-16mm², YJV-0.6/1KV cable is required to be used. Please make sure the
resistance of cable is lower than 1.50hm. If the wire is longer than 20m, preferred to 10-16mm² cable.
Tighten cable with 3.0 mm allen wrench( focus
in dotted box, see figure 5.22). Allen screw is
easy to drop off, don't screw out completely.
*The combination of AC connectors has two seal rings, please refer to different diameters of cable
select corresponding seal ring.
