2. Safety
WARNING
Risk of electric shock
Installation and connection of a DEHNrecord SD may only be carried out by a qualified electrician
in accordance with the installation standards of the country.
Before mounting, check the DEHNrecord SD (DRC SD) and the accessories for external damage.
If any damage or other defect is detected, do not mount the DRC SD.
Loads exceeding the specified values may destroy the DRC SD and the electrical equipment connected to it.
Tampering with and modifying the DRC SD will void the warranty.
If the DRC SD is used together with a surge protective device (SPD) in environments with overvoltage category IV,
make sure that the SPD is functional before accessing the device.
If the SPD indicates a defect, the SPD must first be repaired before the DRC SD can be accessed.
The installation instructions for the SPD must be observed for this purpose.
2.1 Intended use
The DRC SD is permitted for use in the control cabinet and only within the conditions specified in this manual.
If the device is used in a manner not specified, the protection supported by the device may be impaired.
Only approved accessories may be used.
An external time signal from a time server is required for synchronization (see chapter 9.5 Communication via the network)

DEHNrecord SD
Multifunctional measurement and analysis device
for monitoring power quality
Installation instructions
Connection
DRC SD 2 1 – Part No. 910 921
24 V DC external power supply
Detects interruptions and drop > 5 s
as per EN61000-4-30, class A for
24 VDC uninterruptible power supply.
Supply voltage UB: 24 VDC, max. 100 mA
Cross-sectional area L1/L2/L3/N: 1.5 - 6 mm2
Plug cross-sectional area: 0.25 - 1.5 mm2
Test
After applying the voltage:
LED 1 flashes green if power supply correct
LED 2
lights up green if voltage quality good (in factory configuration)
Commissioning
Connect DEHNrecord SD directly to computer
1. Configure computer: IP 192.168.0.10, Sub. 255.255.255.0
2.
Connect computer and DEHNrecord directly with network cable
3.
Activate Web server:Press button 2 briefly, LED 1 lights up blue
4. Access with browser: http://192.168.0.200
Connect DEHNrecord SD via network
1. Connect DEHNrecord SD with network (DHCP)
2.
Activate Web server:Press button 2 briefly, LED 1 lights up blue
3.
Access with browser: http://DRC-SD-serial no. (e.g. http://DRC-SD-FHA12345678)
Factory-set password: smartdevice
Testing
After successful registration, properties such as the following can be checked:
Rotational field direction of the voltage connections, Current measuring coil
connection, Impulse current sensor connection
Configuration
The DEHNrecord SD can be suitably configured via the Web server.
Access to
the cloud server is preconfigured (MQTT, port 8883).
LED 1 lights up green once access to the DEHNmonitor PQ is working.
Product registration
For product registration in the DEHNmonitor PQ,the serial number and the
four digits after the serial number are required. These are only printed on the
device itself! Example: „0000“ in „FHA12345678-0000“.
Example wiring of an SPD with remote
signalling contact:
· Connect SPD contact (connection 11) with
supply voltage 24 VDC (plug I/O tmnl 3)
· Feedback from SPD contact (connection 12 or 14)
to digital input I1.1 (plug I/O tmnl 5)
· Ground connection (plug I/O tmnl 4 and 6)
Installation
The device is installed on a 35 mm DIN rail as per EN 60715.
Backup fuse
The backup fuse
must be chosen to
match the connecting cable;
e.g. for 1.5 mm2-> B16 A
It can be installed together with a surge protective device (SPD).
There are matching busbars for the connection with an SPD.
The snap-on elements of the devices have a permanent unlock-
ing position to facilitate their joint attachment to and removal
from the DIN rail.
Backup fuse
The specifications of the
respective SPD
must be observed.
Connection
DRC SD 1 1 – Part No. 910 920
Power supply via L1 of the measuring voltage
The device can bridge interruptions of supply
for up to 5 s.
Supply voltage UB: 230 VAC (50 Hz), max. 30 mA
Cross-sectional area L1/L2/L3/N: 1.5 - 6 mm2
Plug cross-sectional area: 0.25 - 1.5 mm2
Example wiring of an SPD with remote signalling
contact:
· Connect SPD contact (connection 11) with
auxiliary voltage 12 VDC (plug I/O tmnl 3)
· Feedback from SPD contact (connection 12 or 14)
to digital input I1.1 (plug I/O tmnl 5)
· Ground connection (plug I/O tmnl 4 and 6)
