Figure 5-27 Ring-Type Lug
D (for bolt) 5.0 mm (0.2 in)
W 9.5 mm (0.37 in)
L 7.1 mm to 7.7 mm (0.28 in to 0.3 in)
In order to maintain the insulation route, you must use insulated cable lugs or you must insulate the crimping
zone (for example, by using heat-shrink tube insulation)
Siemens recommends ring-type lugs of the PIDG series made by Tyco Electronics.
Use copper conductors only, at least certified for a temperature of +105 °C. Use prepared solid conductors
intended for single or multi-wiring connection, maximum 2 wires per pole, and for usage of ferrules, crimped-
on pressure wire connectors (ring-type and pin-type).
2 terminal lugs can be installed for each connection.

Figure 5-29 Example of a Current Terminal with Connection of 2 Single Cables
You can connect solid conductors as well as stranded-wire conductors with ring-type lug or bootlace ferrule.
For each connection, you can install up to 2 single cables of the same type and the same cross-section.
