Problem-free and safe operation of the product depends on the following:
•Proper transport
•Proper storage, setup and installation
•Proper operation and maintenance
When electrical equipment is operated, hazardous voltages are inevitably present in certain parts. If proper
action is not taken, death, severe injury or property damage can result:
•The equipment must be grounded at the grounding terminal before any connections are made.
•All circuit components connected to the power supply may be subject to dangerous voltage.
•Hazardous voltages may be present in equipment even after the supply voltage has been disconnected
(capacitors can still be charged).
•Operation of equipment with exposed current-transformer circuits is prohibited. Before disconnecting the
equipment, ensure that the current-transformer circuits are short-circuited.
•The limiting values stated in the document must not be exceeded. This must also be considered during
testing and commissioning.

Design and Hardware Characteristics
The 7SR45 Argus self powered/dual powered non-directional overcurrent and earth fault relay is developed
using the latest generation of hardware technology and is available in multiple variants depending on the
following:
•CT ratings (1 A or 5 A)
•Auxiliary power supply
•Communication configuration
•Binary inputs (2/4)
•Binary outputs (2/4)
•Pulse output
•Local/remote flag indicator
The 7SR45 Argus is a member of Siemens Reyrolle protection devices Argus product family.
The structure of the 7SR45 Argus relay is based on the compact hardware platform. The 7SR45 Argus relay is
supplied in a 4U high, size 4 non-draw-out case . The rear connection comprises user-friendly pluggable type
terminals for pulse and remote flag output, binary inputs, binary outputs, RS485 communication, and auxiliary
input. The CT terminals are suitable for ring-type lug connection to provide a secure and reliable termination.
The hardware design provides a commonality between the products and components across the range of
relays.
