1.7 Disposal
Abide by the national regulations and laws governing the disposal of this de-
vice. Ask your supplier if you are not sure how to dispose of the old equip-
ment.
The directive on waste electrical and electronic equipment (WEEE directive)
and the directive on the restriction of certain hazardous substances in electri-
cal and electronic equipment (RoHS directive) apply in the European Commu-
nity. In Germany, these policies are implemented through the "Electrical and
Electronic Equipment Act" (ElektroG). According to this, the following applies:
 Electrical and electronic equipment are not part of household waste.
 Batteries and accumulators are not part of household waste and must
be disposed of in accordance with the regulations.

3. Product description
3.1 Device features
 Continuous residual current monitoring by means of periodic verifica-
tion
 AC/DC sensitive residual current monitor type B with 6 channels K1…6
(each channel features 2 measuring channels: 1 x RMS, 1 x DC)
 Compatible with RCMS460/490 in a system setup
 Ideal for applications with space limitations
 Easy DIN rail or screw mounting to standard distribution panels
 2 separately adjustable response values (DC or RMS) per channel
 Continuous self monitoring
 Fully shielded measuring current transformers to avoid external influ-
ences due to magnetic fields that may cause disturbances
 Compatible with Bender gateways of type COM465IP, CP700
 Up to 534 measuring channels in the monitored system that can be
combined via BMS bus
 RS-485 interface with BMS bus (Modbus RTU on request)
 BMS address range 2…90
3.2 Function description
The residual currents are recorded and evaluated as r.m.s. values in the fre-
quency range DC…2 kHz. The response values can be set via the connected
gateways.
The user can set four response values per channel K1…6:
IΔn1 RMS , IΔn2 RMS, IΔn1 DC, IΔn2 DC
The response values IΔn1…apply to the prewarnings,
the response values IΔn2…apply to the alarms.

Product description
14 RCMS150_D00259_00_M_XXEN/08.2016
If one of the four set response values IΔN… is exceeded, the assigned response
delay ton… starts. If the response value continues to be exceeded, the corre-
sponding message (prewarning or alarm) is displayed on the gateway after
the response delay ton… has elapsed.
In the event of an alarm, the alarm LED of the respective channel K1…6 lights
up yellow.
If the recorded residual current falls below the release value (response value
minus hysteresis) the delay on release toff begins. If the value remains below
the release value after toff has elapsed, the message on the gateway is reset. If
the alarm LED of the respective channel has been lit, now it goes out.
A pending response value violation is emitted via the BMS interface with ad-
dress and measuring channel indication and can be evaluated by means of a
gateway.
All devices can be accessed via the network from any PC using a standard web
browser (Firefox, Internet Explorer). Like this, all relevant measurement data
of the monitored system are available. All device-related parameters of the
RCMS150 can be set via the gateway technology.
To ensure the device function, a continuous automatic self test is run, which
monitors the function of all measuring current transformers. In the event of a
device error, all alarm LEDs flash.

4.1.1 Important information on mounting
 Mounting is to be carried out with suitable equipment and tools
according to the documentation.
 The device must only be installed by appropriately qualified personnel
in de-energised state. Disconnect the switchboard cabinet from the
power supply and protect the system against accidental switch-on.
Only qualified personnel are permitted to carry out the
work necessary to install, commission and run a device or
system.
Risk of electrocution due to electric shock!
Touching live parts of the system carries the risk of:
 An electric shock
 Damage to the electrical installation
 Destruction of the device
Before installing and connecting the device, make sure
that the installation has been de-energised. Observe the
rules for working on electrical installations.
If you are familiar with the configuration of computer
networks, you can carry out the connection of the RCMS150
yourself.
Otherwise please contact your EDP administrator!

4.4 Commissioning
1. Mount the RCMS
2. Set the BMS address (set the detent potentiometers 5 and 6 to the
corresponding position using a screwdriver). Address range: 2…90
Risk of short circuit!
Only insulated conductors with an insulation that is suitable
for at least the monitored voltage may be routed through the
measuring current transformer.
The rated voltage of the RCMS150 must not be exceeded.
When assigning the BMS bus addresses make sure that each
address is only assigned once on the bus!
The beginning and the end of the BMS bus require a 120 Ω
terminating resistor!
On the BMS bus, the transmission of alarm messages takes
priority over the transmission of all other messages. The
messages are cyclically scanned every 1…2 s. In bus systems
with many bus devices, the update of operational status
messages may take several seconds.
CAUTION

Installation, connection and commissioning
20 RCMS150_D00259_00_M_XXEN/08.2016
3. Route outgoing circuits to be monitored through the current trans-
formers.
4. Connect the RCMS150 to the supply voltage (DC 24 V)
5. Connect the RCMS150 to the master CP700/COM465IP
(software version ≥ 2.1, option C)
Risk of short circuit!
Only insulated conductors with an insulation that is suitable
for at least the monitored voltage may be routed through the
measuring current transformer.
The rated voltage of the RCMS150 must not be exceeded.
Do not route any protective earth conductors through the
measuring current transformers
(see wiring diagram)!
The ON LED flashes to indicate the set BMS bus address after
the device has been switched on or after the address has
been changed: ones' position - pause - ten's position.
Example: ***** *** designates the BMS bus address 35.
After indicating the address, the RCMS150 changes
automatically into display state.
If the ON LED flashes quickly, the BMS bus address has been
set incorrectly.
CAUTION
