Connections of Current Terminals
Fasteners
The fasteners for the transformer connection are part of the current terminal (housing side). They are made of
a stress-crack and corrosion-free alloy. The head shape of the clamping screw allows the use of a DIN 5.5 x 1.0
screwdriver or a PZ2 screwdriver. Siemens recommends a PZ2 screwdriver.
Connection Elements and Conductor Cross-Sections
The following connection types are possible:
•
Stranded-wire conductor with ring-type lug
•
Stranded-wire conductor with bootlace ferrule
•
Solid conductor
Siemens recommends the use of ring-type lugs with the dimensions shown in the following figure. Use copper
cables only.
