The numerical, multi-functional SIPROTEC
bicle mounting is a sealed device in a 7XP20
different general types of terminals are available, threaded terminals and plug-in ter-
minals. The terminals provided depend on the order number of the device.
The major components of a 7SJ62 are the front panel, the case, and the rear panel.
The terminals for connections to external equipment are located on the rear panel,
which is bolted to the case. Inside the device are two printed circuit boards that have
the rear serial interface modules attached. The boards are connected together via a
ribbon-cable that has plug connectors. The boards are connected to the terminals and
supported in guide rails.
The front panel is removable. The screws for removing the component are located be-
hind the four covers at the corners. The front panel has a covered keypad with oper-
ating and display elements necessary for equipment operation. All connections for
these elements are combined into an adapter module on the front panel that is linked
via a ribbon-cable with plug connectors to the internal processor board (CPU).
The nameplate sticker, showing important information such as power supply rating,
nominal current rating, and ordering number, is located on the top of the case and the
interior of the front panel.
