E50417-K1150-C342-A6, Edition 07.2010
Connections of the Voltage Terminals
Fixing Elements
The fixing elements for the voltage transformer connection are part of the
voltage terminal (housing side). They have a stress-crack- and corrosion-
resistant alloy. The head shape of the terminal screw allows for using a
flat screwdriver (4.0 mm x 0.8 mm / 0.16 in x 0.031 in) or a crosstip screw-
driver (PZ1). PZ1 is recommended.
Cable lugs and Wire Cross-sections
The connection mode available is the connection as single wire. As single
wires, solid conductors as well as stranded conductors with or without
conductor sleeves can be used. For the connection of two single wires we
recommend to use twin connector sleeves. We recommend twin connec-
tor sleeves of the PN 966 144 range from Tyco Electronics.
When connecting single wires, the following cross-sections are allowed:
With vertically arranged terminal points, single conductors and short cir-
cuit links (order no. C53207-A406-D194-1) can be connected together.
Make sure that the short circuit links are connected in alternate sides.
Mechanical Requirements
The fixing elements and the connected components are designed for the
following mechanical requirements:
Wire cross-sections: AWG 20-14
(0.5 mm
2
to 2.0 mm
2
)
Conductor sleeve with plastic sleeve L = 10 mm (0.39 in) or
L = 12 mm (0.47 in)
Stripping length:
(when used without conductor sleeve)
12 mm (0.47 in)
Only copper wires may be
used.
Permissible tightening torque at the terminal
screw
1.0 Nm (8.85 lb.in.)
Permissible traction per connected conduc-
tor
50 N based on IEC 60947-
1 (VDE 660, Part 100)
