3 Product description
3.1 Functional description and components
3.1.1 Function
The leak sensor monitors the floor of the room for con-
ductive liquids (leaks). If a liquid is detected, it reports
this to the connected CMC III Processing Unit. The leak
sensor has an identification that allows it to be detected
automatically by the CMC III Processing Unit.
3.1.2 Components
The device consists of a compact plastic housing in
RAL 7035 with a ventilated front in RAL 9005, together
with a sensor probe.
3.2 Proper use, foreseeable misuse
The CMC III leak sensor should only be used to monitor
the floor of the room for conductive liquids. It must only
be used together with the CMC III PU. Any other use is
not permitted.
The unit is state of the art and built according to recog-
nised safety regulations. Nevertheless, improper use
can pose a threat to the life and limb of the user or third
parties, or result in possible damage to the system and
other property.
Consequently, the unit must only be used properly and
in a technically sound condition! Any malfunctions which
impair safety should be rectified immediately. Follow the
operating instructions!
Proper use also includes the observance of the docu-
mentation provided and compliance with the inspection
and maintenance conditions.
Rittal GmbH & Co. KG is not liable for any damage which
may result from failure to comply with the documenta-
tion provided. The same applies to failure to comply with
the valid documentation for any accessories used.
Inappropriate use may result in danger. Inappropriate
use includes:
– Use of impermissible tools.

5 Installation
5.1 Safety instructions
 Please observe the valid regulations for installation in
the country in which the leak sensor is installed and
operated, and the national regulations for accident
prevention. Please also observe any internal company
regulations, such as work, operating and safety regu-
lations.
 The technical specifications and limit values stated
must not be exceeded under any circumstances. In
particular, this applies to the specified ambient tem-
perature range and IP protection category.
 If a higher IP protection category is required for a spe-
cial application, the leak sensor must be installed in an
appropriate housing or in an appropriate enclosure
with the required IP protection category.
5.2 Siting location requirements
To ensure proper functioning of the unit, the conditions
for the installation site of the unit specified in section 8
"Technical specifications" must be observed.
Electromagnetic interference
– Interfering electrical installations (high frequency)
should be avoided.
5.3 Installation procedure
5.3.1 Connecting and installing the sensor probe
Fig. 2: Rear of the leak sensor
Key
1 CAN bus connection, 24 V
2 CAN bus connection, 24 V
3 Universal interface
4 Sensor probe with cables

Connect the sensor probe connector to the universal
interface (fig. 2, item 4).
 Lay the sensor to the measuring point.
 Using the cable ties provided, fit the sensor probe so
that the contacts are pointing vertically downwards to-
wards the floor.
Fig. 3: Installing the sensor probe
On free surfaces, a bracket may be used to secure the
sensor to the floor, such as Rittal mounting bracket
4597.000 (fig. 3). The sensor probe is then attached to
the bracket using the cable ties provided.
5.3.2 Installing the electronic unit with the
mounting bracket provided
The electronic unit can be mounted on the frame of the
IT enclosure using the bracket provided.
 Place the leak sensor on the bracket from above.
Fig. 4: Attaching the sensor to the bracket
 Move the sensor sideways slightly on the bracket so
that it latches into place.
Fig. 5: Latching the sensor into place on the bracket
 Mount the bracket including leak sensor in the desired
position in the enclosure or the IT enclosure using the
screw included in the scope of delivery.
Note:
In order to be able to detect leaks rapidly, the
contacts of the sensor probe should be fitted
as close as possible to the floor, approxi-
mately 1 to 2 mm above it.

5.3.3 Installing the electronic unit on a top-hat
rail
The sensor can also be mounted on a top-hat rail using
the bracket along with the spring clip included in the
scope of delivery.
 First screw the bracket onto the spring clip provided
for installation on a top-hat rail.
Fig. 7: Fastening the bracket to the spring clip
 Then place the leak sensor on the bracket (fig. 4) and
latch it into place (fig. 5).
 Latch the spring clip into place at the desired position
on the top-hat rail.
Fig. 8: Fastening the spring clip to the top-hat rail
5.4 Connecting the electronic unit
The CAN bus connection supplies the leak sensor with
the necessary operating voltage. There is no need to
connect a separate power supply unit.
 Use a CAN bus connection cable to connect the leak
sensor to a CAN bus interface on the
CMC III Processing Unit or the neighbouring compo-
nent on the CAN bus (fig. 2, item 2).
The following CAN bus connection cables from the
CMC III accessories range may be used:
– 7030.090 (length 0.5 m)
– 7030.091 (length 1 m)
– 7030.092 (length 1.5 m)
– 7030.093 (length 2 m)
– 7030.480 (length 3 m)
– 7030.490 (length 4 m)
– 7030.094 (length 5 m)
– 7030.095 (length 10 m)

ually in the sequence green – orange – red.
– The multi-LED of the leak sensor flashes blue con-
tinuously.
 Press the "C" key on the CMC III Processing Unit (an
initial audio signal will sound) and keep it pressed for
approx. 3 seconds until a second audio signal is
heard.
Status change display on the CAN bus LEDs
– Continuous green LEDs: CAN bus status "OK".
– Continuous red LEDs: CAN bus status defective.
Status change display on the multi-LED of the Pro-
cessing Unit

CAN bus have the status "OK".
– Continuous orange light: At least one device connect-
ed to the CAN bus has the status "Warning".
– Continuous red light: At least one device connected to
the CAN bus has the status "Alarm".
Status change display on the multi-LED of the leak
sensor
– Continuous blue flashing: Communication via the CAN
bus.
– Green flashing: When the measured value changes, or
at least every 5 seconds.
– Continuous red flashing: The leak sensor has the sta-
tus "Alarm".
– Continuous red light: Invalid measured value.
