Figure 3-5
For complying with the required insulation clearances, insulated ring lugs have to be used. Otherwise, the
crimp zone has to be insulated with corresponding means (e.g. by pulling a shrink-on sleeve over).
We recommend ring lugs of the PIDG range from Tyco Electronics.
Two ring lugs can be mounted per connection.

Figure 3-6
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
arrangement. When using jumpers, only ring lugs are allowed.
When connecting single wires, the following cross-sections are allowed:
Cable cross-section:
Connector sleeve with plastic collar
Stripping length:
(when used without conductor sleeve)
Mechanical Requirements
The fixing elements and the connected components are designed for the following mechanical requirements:
Permissible tightening torque at the terminal screw
Permissible traction per connected conductor
