Connections for Auxiliary Voltages, Binary Inputs and Binary Outputs
Fixing Elements
The fixing elements for the connection of auxiliary voltage, binary inputs
and binary outputs are part of the terminal blocks (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 screwdriver (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.
