3 Product description
3.1 Functional description and components
3.1.1 Function
The leak sensor monitors the floor of the room for liquids
(leaks) over the entire length of the sensor cable, apart
from the section in front of the yellow mark at the con-
nection end, where no leaks are detected. If a liquid is
detected, the leak sensor reports this to the connected
CMC III PU. It contains an identifier that allows it to be
detected automatically by the CMC III PU.
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 cable.
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 be dangerous. Inappropriate use
includes:
– Use of impermissible tools.
– Improper operation.
– Improper rectification of malfunctions.
– Use of accessories not approved by Rittal GmbH &
Co. KG.

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 correct 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 cable
Fig. 2: Rear of the leak sensor
Key
2 CAN bus connection, 24 V
3 CAN bus connection, 24 V
4 Universal interface
5 Sensor cable
Leave the sensor cable on the transport coil until you are
ready to lay it.
To lay the sensor cable, carefully wind the transport
coil so that the cable is unrolled without twisting, and
positioned directly at the installation location.
Connect the sensor cable connector to the universal
interface (fig. 2, item 4).
Lay the sensor cable on the floor inside the area to be
monitored.
To do so, first stick the supplied retaining clips to the
floor using the adhesive.
Then press the sensor cable into the clips.
5.3.2 Installing the electronic unit with the pro-
vided bracket on the enclosure frame
The provided bracket is used for installation of the elec-
tronic unit on the frame of an IT enclosure.
For installation on a TS IT enclosure, break off the pro-
truding lugs at the rear of the bracket.
Fig. 3: Preparing the bracket for installation on a TS IT enclo-
sure
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.
Note:
The sensor cable must not be twisted or
kinked while unrolling, and must not be trod-
den on after laying. Otherwise, a short-circuit
may occur, leading to a defect in the sensor
cable.
Note:
The sensor cable has a section of approxi-
mately 2.5 m at the connection end where no
leaks are detected. The start of the sensor
cable itself is indicated by a yellow marker.

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.
Then place the leak sensor on the bracket and latch it
into place.

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 Process-
ing Unit or the neighbouring component on the CAN
bus (fig. 2, item 2).
The following CAN bus connection cables from the
CMC III accessories range may be used:
– DK 7030.090 (length 0.5 m)
– DK 7030.091 (length 1 m)
– DK 7030.092 (length 1.5 m)
– DK 7030.093 (length 2 m)
– DK 7030.480 (length 3 m)
– DK 7030.490 (length 4 m)
– DK 7030.094 (length 5 m)
– DK 7030.095 (length 10 m)

Key
1 Multi-LED for status display
The sensor software is updated, if necessary, following
connection. The status LED of the leak sensor glows
blue throughout and also flashes purple during the entire
update process.
In addition, the status LED of the CMC III Processing
Unit flashes white and a corresponding message ap-
pears on the website.
The sensor update is complete when the following con-
ditions have been fulfilled:
1. The LEDs on the CAN bus connection of the sensor
are green.
2. The multi-LED of the sensor behind the front panel
flashes blue and also green or red, depending on the
status of the sensor.
Further components are connected as a daisy chain.
If necessary, connect another component (e.g. anoth-
er sensor type) to the second, free CAN bus interface
of the leak sensor (fig. 2, item 3).
Status change display:
– The two green and the two red CAN bus LEDs on
the CAN bus connection flash.
– The multi-LED of the Processing Unit flashes contin-
ually in the sequence green – orange – red.
– The multi-LED of the leak sensor flashes blue con-
tinuously.
Press the "C" button 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
– Continuous green light: All devices connected to the
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.
Note:
No settings can be made as long as the up-
date process is running.
Note:
See section 6.3.1 "Multi-LED displays" for a
list of all of the multi-LED displays.

7 Storage and disposal
7.1 Storage
If the device is not used for a long period, Rittal recom-
mends that it be disconnected from the mains power
supply and protected from damp and dust.
7.2 Disposal
Since the leak sensor consists mainly of the "housing"
and "circuit board" parts, the device must be passed on
to the electronic waste recycling system for disposal.
