Terminals accept solid or stranded copper from 0.75 mm² up to 35 mm², with a tightening torque of 2.5 to 3.5 N·m — spring-cage feel but screw-type. Polarity matters on the DC supply cord; the datasheet flags it.
The depth is 76 mm, with an installation depth of 70 mm, fitting standard DIN-rail enclosures.
Solid and stranded copper from 0.75 mm² up to 35 mm², terminated with screw-type terminals torqued to 2.5–3.5 N·m.
