Spring Terminal Connection Technique - Siemens SIWAREX JB Instruction Manual

Revision 03.06

2.4 Spring Terminal Connection Technique

A screwdriver with a maximum blade width of
2.5 mm is required to connect the cables. It is
pressed into the rectangular opening (1). This
opens the spring bracket. The stripped cable is
pushed through the round opening to the stop (2).
The cable is contacted tightly in the spring bracket
by pulling out the screwdriver (3). (Fig. 2-7)
The cables are stripped
8 to 9 mm. (Fig. 2-8)
IMPORTANT
With smaller cable cross sections there is a danger of the stripped wire being
snapped off when inserting in the terminal. The line is then connected to the
insulation. The result is contact problems. Crimp-on sleeves prevent these
problems.
The following cables can be connected.
0.08 to 1.5 mm
Single-wire, multi-wire, fine-wire – also with tinned single wires, fine-wire –
stranded wire compressed and fine wire with gas-tight crimp-on pin cable shoe.
0.08 to 1 mm
Fine wire with gas-tight crimped on end sleeves.
