Connections Of The Voltage Terminals; Interface Modules - Siemens SIPROTEC 7RW80 Manual

3.1.2.2 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 screwdriver (PZ1). PZ1 is recommended.
Cable Lugs and Wire Cross-sections
The connection mode available is the connection as single cable. As single cables, solid conductors as well as
stranded conductors with or without conductor sleeves can be used. For the connection of two single cables
we recommend to use twin connector sleeves.. We recommend twin connector sleeves of the PN 966 144
range from Tyco Electronics.
When connecting single cables, the following cross-sections are allowed:
Cable cross-sections:
Connector sleeve with plastic collar
Stripping length:
(when used without conductor sleeve)
With terminal points lying one below the other you may connect single conductors and jumpers (Order No.
C53207-A406-D194-1) together. Please make sure that neighboring jumpers are built in/connected alternately.
Mechanical Requirements
The fixing elements and the connected components are designed for the following mechanical requirements:
Permissible tightening torque at the terminal screw
Permissible traction per connected conductor

3.1.2.3 Interface Modules

General
The 7RW80 relay is supplied with preconfigured interfaces according to the ordering version. You do not have
to make any adaptations to the hardware (e.g. plugging in jumpers) yourself, except for the installation or re-
placement of communication modules.
The use of the interface modules RS232, RS485 and optical can be defined via the parameter 617 ServiProt.
This parameter is only visible if the 11th digit of the ordering number was selected to be 1 for RS232, 2 for
RS485 or 3 for optical.
