Stripping length:
(when used without conductor sleeve)
12 mm (0.47 in)
Only copper cables may be used.
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 alter-
nately.
Mechanical Requirements
The fixing elements and the connected components are designed for the following mechanical requirements:
Permissible tightening torque at the terminal screw 1.0 Nm (8.85 lb.in)
Permissible traction per connected conductor 50 N based on IEC 60947-1
(VDE 660, Part 100)
Interface Modules
General
The 7SJ80 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
replacement of communication modules.
The use of the interface modules RS232, RS485 and optical can be defined via the parameter 617 ServiProt
(CM). 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.
Installation or Replacement of the Ethernet Interface Module
The following requirement must be fulfilled:
There is no SIPROTEC 4 communication module mounted yet. Otherwise, this has to be removed before
actually installing the Ethernet interface module (see below).
The Ethernet interface module is inserted in the respective slot, most suitably from the open bottom, i.e.
above the back of the battery case. A supporting frame is placed over the modular plug. The narrow spacer lies
at edge of the printed circuit board. The module is attached to the 50-pole plug connector of the CPU module
slightly inclined to the basic I/O board. The supporting plate is slightly pulled outwards in this area. The
module can now be inserted vertically up to the stop. Then, the supporting plate is pressed against in the area
of the locking latch until the upper edge of the printed circuit board of the Ethernet interface module snaps
into the locking latch.
