Usage information
e.Guard RCM F 025 residual current monitor
This usage information describes the installation and commissioning
of the e.Guard RCM B 025 and F 025 residual current monitors. It is
intended for use by qualified electricians. Due to the considerable
potential dangers, electrical laypersons must not install and connect
devices of this type. The instruction must be kept so that they can be
referred to at a later stage.
Warning notes
1. Devices with visible damage must neither be installed nor used.
2. Residual current monitors (RCM) are not intended for protection against electric
shock in accordance with VDE 0100 Part 530.
3. The installation regulations applicable to the RCM application must be observed.
Intended use and installation
Residual current monitors in accordance with DIN EN 62020 are used for the detec-
tion and signalling of residual currents in electrical systems, especially those in TN-
S, TN-CS and TT networks. Use in IT networks is possible, but may be restricted by
installation regulations. e.Guard RCM F 025 is sensitive and detect type B residual
currents from DC to 100 kHz. The residual current monitors are suitable for monitor-
ing both AC and DC networks.
According to VDE 0100 Part 530, residual current monitors may be used in connec-
tion with a circuit-breaker for installation switch-off in order to prevent electrical fires
caused by insulation faults, insofar as residual current circuit-breakers are rejected
for technical reasons. The devices are designed for installation in power distribu-
tors or systems in dry indoor conditions, regardless of their position. The device is
mounted on a DIN rail.
We recommend operating the RCM in a separate network with a fixed IP address.
The network should be set up, managed and operated according to the current state
of the art.
Wiring diagram
For correct functioning, the e.Guard RCM F 025 device requires a supply voltage of
24 V DC. The connection of 24 V DC and PoE (48 V DC) is also possible simultaneously
to obtain redundancy.

The active conductors to be monitored should be fed through the inner hole of the
sensor as symmetrically as possible. The direction of energy flow is arbitrary. The
protective conductor must not be fed through.

Technical properties
The e.Guard-software provides an overview of all RCMs in the network and ena-
bles their simple management and visualisation of the residual currents. Additional
residual current monitors in the network can be easily added by assigning them via IP
address. A residual current is signalled via two built-in relays. Their threshold values
can be set in the e.Guard-software.
The e. Guard RCM can also be operated without software.
The following parameters are preset when the device is delivered:
analysis
AC total
alarm 1 225 mA
alarm 2 150 mA
S Thresholds when delivered
Note: Only the alarm thresholds of the main analysis are activated.
Individual alarm thresholds for the potential-free contacts can be parameterised in
the software, which are then stored on the sensor. The potential-free contacts then
react to the parameterised alarm thresholds.
Four LED lights are integrated into the casing to signal that the device is working
correctly:

IP is being obtained via DHCP or being switched

up to three minutes.

The rated current specified in the data sheet is the current with which the e.Guard
RCM can be permanently operated. However, due to various consumers, e.g. motors,
the flowing load current can be a multiple of the rated current over a short period of
time. As a result of physical effects in the material of the transformer, these inrush
currents – depending on size and line structure – may incorrectly result in residual
currents being indicated. This effect can be minimised by centred installation of lines
routed through the RCM. If this is not possible, the maximum preload can be taken
from the table. With the factory settings of the e.Guard RCM, a current flow of six
times the rated current does not trigger alarm 1 (setting: 225 mA).

Function of the transformer's test button:
Pressing the test key located on the side of the device results in an internal residual
current being generated by the transformer. It is also possible to connect an external
test key with an NO contact in parallel to the terminal strip if the transformer is not
mounted to accessible parts of an installation. Its detection corresponds to a func-
tion test of the analysis unit including the signal contacts.
» Press briefly: The transformer generates an internal residual current.
potential-free contacts of the transformer also switch in this case. Its detection
therefore corresponds to a function test of the analysis unit including the signal
contacts.
» Press and hold down (10 s): DHCP will switch back on automatically if it was
previously deactivated.
Relay response times
A response delay can be set for each relay in the e.Guard-software (factory default:
0 ms). This prevents excessive switching in the case of a heavily fluctuating residual
current.
Warranty
All professionally installed, unaltered devices are covered by warranty for the
duration of the statutory warranty period from the day of purchase by the end user.
The warranty does not apply to damage incurred during transport or caused by
short-circuit, overloading or improper use. Should any defects in workmanship or
material be discovered within the warranty period, the company will provide repair
or replacement free of charge.
e.Guard-software
With the e.Guard-software, you can easily and centrally
manage your RCMs.
The software also visualizes and documents
the detected differential currents.
