As single wires, solid conductors as well as stranded conductors with conductor sleeves can be used. Up to
two single wires with identical cross-sections can be used per connection.
Alternatively jumpers (Order No. C53207-A406-D193-1) can be used with terminal points in a stacked arrange-
ment. When using jumpers, only ring lugs are allowed.
When connecting single wires, the following cross-sections are allowed:
Mechanical Requirements
The fixing elements and the connected components are designed for the following mechanical requirements:
Cable cross-section: AWG 14-10 (2.0 mm
2
to 5.2 mm
2
)
Connector sleeve with plastic collar L = 10 mm (0.39 in) or L = 12 mm (0.47 in)
Stripping length:
(when used without conductor sleeve)
15 mm (0.59 in)
Use exclusively solid copper conductors.
Permissible tightening torque at the terminal screw 2.7 Nm (23.9 lb.in)
With solid conductors the allowed
maximum tightening torque is 2 Nm
Permissible traction per connected conductor 80 N based on IEC 60947-1 (VDE 660, Part
100)
