Mounting and Commissioningg
Mounting
The physical dimensions of the relay and the required cut-out
dimensions are shown in Figure 1.
1. As per the relay selection, create a slot of dimensions (in mm) to
house the relay in the Low Voltage (LV) compartment.
2. Insert the rear-side of relay into the RMU/LV compartment cut-out.
3. Fasten the relay with 4 M4x20 Pan Philips stainless-steel screws and
nuts provided in the relay packing box with a torque of
0.5 Nm to 0.6 Nm.
4. Carry-out all other installation steps and wiring connections from
the LV compartment.
5. In the rear terminal of the relay, execute the wiring process as
mentioned in the terminal diagram.
For more details on terminal connector diagram, refer to
Figure 2.
Refer to Table 1 for the recommended terminal lugs to be used.
If needed, use washers from the kit to connect the current
inputs.
6. The grounding cable must be wired as indicated in the Figure 2
using a non-stranded cable of 4 mm2/6 mm2.
This cable must be terminated in the shortest possible path
to the ground terminal/bus bar in LV compartment.
7. Maintain a minimum clearance (in mm) from the relay as given
in Figure 1 to ensure safety and accidental touch of terminals.
8. In case the work area is restricted in a cubicle, then suitable
protective terminals to be provided.

Preparing for Commissioning
If the following criteria are satisfied, then proceed with the
commissioning tests:
1. Equipment has not been damaged in transit (physical damage).
2. Equipment has been correctly connected and installed.
3. Gland insulator from the battery compartment is removed.
4. Characteristics of the protection and settings are based on
calculations.
5. Relay thermal ratings have been considered before selecting the
specific CT. Refer to 7SR46 Device Manual for more information.
6. Confirm that settings have been correctly applied.
7. Synchronize the RTC via Reydisp Evolution or through HMI.

Do’s s
Follow the Do’s when installing the 7SR46 Argus Relay:
•During installation, follow the instructions provided herewith.
For more information, refer to 7SR46 Operating Manual.
•Before energizing the relay, ensure that the relay is grounded
using ground terminal on the back plate. Refer to Figure 2.
•Use Auxiliary/CT/USB Power to configure the relay settings to
avoid any unnecessary consumption of battery power.
•Check the time duration and BI, BO operation counts on battery
power in Instrument menu.
•Maintaining a set of test results for future reference is
recommended.
•Remove the paper strip between battery clip and battery before
device is put in service.
Don’ts s
Follow the Don’ts when working with the 7SR46 Argus Relay:
•Do not attempt to remove the relay without disconnecting all the
wires.
•Do not use non-recommended Specific CT. Refer to 7SR46 Device
Manual for Specific CT details.
•Do not replace the battery with a battery that is not recommended
from Siemens. Refer to 7SR46 Hardware Manual for battery details.

Setting and Configuring the Relay using Reydisp Evolution s
To set the relay using a communication port:
PC with Reydisp Evolution Version 9.51 or higher installed. This can
be downloaded from our website http://www.siemens.com/reyrolle.
Go to Products & Services > Energy > Energy automation and smart
grid > Protection for digital substation > Engineering tools for
protection > Reydisp Evolution > Downloads. This software requires
Windows 7 or Windows 10.
NOTE:
Select Properties > Advanced > check Do NOT Check
Communications Connection in check box settings.
When Reydisp Evolution is running, all the available communication
ports will automatically be detected. On the start page tool bar, open
the sub-menu Fileand select Connect.
The Connection Manager window displays all available
communication ports. With the preferred port highlighted, select
the Properties option and ensure the baud rate and parity match
that selected in the relay settings. Select Connect to initiate the
relay PC connection.

Output Test and Trip Pulse Test
After commissioning the relay, the operator can execute the output
test, trip pulse test and verify the binary outputs assigned to the
corresponding functions.
To execute the output test in the relay, follow the procedure:
1. In the Settings mode, select Maintenance and Output Test.
2. For testing, select output by pressing ENTER.
3. Select Yes/No.
4. Perform the test by pressing ENTER.
Output test can be conducted with Auxiliary power, CT power,
USB power and battery.
To execute the trip pulse test in the relay, follow the procedure:
1. In the Settings mode, select Maintenance and Trip Pulse Test.
2. For testing, select output by pressing ENTER.
3. Select Yes/No.
4. Perform the test by pressing ENTER.
Trip pulse test can be conducted with Auxiliary power, CT power
and USB power only.
Troubleshooting
This section provides the common problems of 7SR46 Relay and the
recommended solution to resolve the problem.
Observation
Action
Relays will not
communicate in a
ring network
•
Check that all relays are powered up with
auxiliary power supply.
•Check that all relays have unique addresses.
•In self-powered mode, check CT input current
above 1.62 ⋅ Ismin (1-phase) or
0.6 ⋅ Ismin (3-phase).
Relay does not
power up
•Check whether correct auxiliary AC or DC
voltage is applied, and the polarity is correct.
•Check whether phase connections are based
on the terminal diagram and if CT power is
applied.
•Check USB port, if the relay is connected with
USB power.
•Check the battery healthy voltage if the relay
is powered with battery power.
Relay does not
accept the
password
•Password entered is wrong. Enter the correct
password.
•If correct password is forgotten, note down
the numeric code displayed at the Change
Password screen.
•To retrieve the password, communicate this
numeric code to a Siemens customer care
representative.
Healthy LED
OFF/LCD not
displaying
•In the absence of auxiliary voltage, check the
minimum phase currents.
•Check error messages and error codes in the
Instrument Mode.
Cannot
communicate with
the relay
•Check whether communication cable is
connected properly.
•Check that the USB driver is installed
correctly.
•In Reydisp Evolution, verify that “Do NOT
Check Communications Connection”is
selected in the Advanced properties.
•In Reydisp Evolution, check that the Relay
Address is set as “1” in the Relay menu.
•Ensure that IEC 60870-5-103 is specified for
the connected port (COM1 or COM2).
Binary inputs do
not work
•Check that the correct BI voltage is applied,
and that the polarity is correct.
•Check that the binary input settings such as
the pick-up and drop-off timers and the status
inversion function are correctly set.
External trip (ET)
input does not
work
•Check whether the device is working on CT
power or aux power and ensure that the
device is operating in healthy condition.
•Short the ET terminals with a resistance wire
and ensure that the line wire resistance is less
than or equal to 20 Ω.
Low/critical battery
indication
•Check whether paper strip between battery
clip and battery is removed.
•Check whether battery is connected to the
correct polarity.
•Check the battery healthy voltage.
