Permissible tightening torque at clamping screw 2.7 Nm
For solid conductors, the max. permissible tightening
torque is 2 Nm.
Permissible tensile force for each connected
conductor 80 N following IEC 60947-1 (VDE 660, part 100)
Connections of Voltage Terminals
Connections of Voltage Terminals with Spring Clips
Fasteners
The fasteners for the voltage connection are part of the voltage 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 4.0 x 0.8
screwdriver or a PZ1 Phillips screwdriver. Siemens recommends a PZ1 Phillips screwdriver.
Connection Elements and Conductor Cross-Sections
The single cable connection type is available for the connection. You can connect solid conductors as well as
stranded-wire conductors with and without bootlace ferrule as single cables. Siemens recommends using twin
bootlace ferrules of series PN 966 144 made by Tyco Electronics for the connection of 2 single cables.
The following cable cross-sections can be used for the connection of single cables:
Cable cross-section AWG (American Wire Gauge) 20-14 (0.5 mm
2
to
2.5 mm 2 (0.0008 in 2 to 0.0039 in 2 )) solid
or bare stranded wire with or without UL listed boot-
lace ferrule
Use AWG 14 (2,5 mm
2 (0.0039 in 2 )) for currents from
5 A to 10 A.
Use copper conductors only, at least certified for a
temperature of +105 °C (221 °F).
Bootlace ferrule with plastic shroud L = 12 mm (0.47 in)
Stripped length (for use without bootlace ferrule) 12 mm (0.47 in), only copper lines may be used.
Single cables and bridges can be connected together for horizontally arranged clamping points. Note that
adjacent bridges are installed reciprocally.
