3 Product description
3.1 Function description and components
3.1.1 Function
The temperature/humidity sensor serves to measure the
temperature and relative humidity at the installation loca-
tion. It provides the temperature and air humidity values
measured to the connected CMC III Processing Unit.
The temperature/humidity 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.
3.2 Proper use, foreseeable misuse
The temperature/humidity sensor serves exclusively to
measure the temperature and relative humidity in a serv-
er enclosure. It may only be used together with the
CMC III Processing Unit. Any other use is not permitted.
3.3 Scope of supply
– CMC III temperature/humidity sensor

5 Installation
5.1 Safety instructions
 Please observe the valid regulations for installation in
the country in which the temperature/humidity sensor
is installed and operated, and the national regulations
for accident prevention. Please also observe any com-
pany-internal regulations, such as work, operating and
safety regulations.
 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 degree of protection.
 If a higher IP protection class is required for a special
application, the temperature/humidity sensor must be
installed in an appropriate housing or in an appropriate
enclosure with the required IP degree of protection.
5.2 Siting location requirements
To ensure the correct function 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
There are two general options for installing the tempera-
ture/humidity sensor:
1. Installation on the frame of the enclosure or IT enclo-
sure using the bracket included.
2. Installation on a top-hat rail using the bracket includ-
ed along with a spring clip.
5.3.1 Installation notes
 Precise temperature measurement with the internal
sensor requires adequate air circulation inside the en-
closure or the IT enclosure. In addition, the tempera-
ture/humidity sensor must be positioned so that it is
ventilated with an adequate amount of air and the ven-
tilation slots are not covered.
5.3.2 Installation with the mounting bracket pro-
vided
It can be mounted on the frame of the IT enclosure using
the bracket included in the scope of delivery.
 Place the temperature/humidity sensor on the bracket
from above.
Fig. 2: Attaching the sensor to the bracket
 Move the sensor sideways slightly on the bracket, so
that it latches into place.
Fig. 3: Latching the sensor into place on the bracket
 Mount the bracket and the temperature/humidity sen-
sor in the desired position in the enclosure or the IT en-
closure using the screw included in the scope of
delivery.
Fig. 4: Mounting the sensor in the enclosure or IT enclosure
5.3.3 Installation 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.

5 Installation
EN
 First screw the bracket onto the spring clip provided
for installation on a top-hat rail.
Fig. 5: Fastening the bracket to the spring clip
 Then place the temperature/humidity sensor on the
bracket (fig. 2) and latch it in place (fig. 3).
 Latch the spring clip into place at the desired position
on the top-hat rail.
Fig. 6: Fastening the spring clip to the top-hat rail
5.4 Connecting the sensor
The CAN bus connection supplies the temperature/hu-
midity sensor with the necessary operating voltage. A
separate power supply unit does not need to be con-
nected.
 Use a CAN bus connection cable to connect the tem-
perature/humidity sensor to a CAN bus interface on
the CMC III Processing Unit or the neighbouring com-
ponent on the CAN bus (fig. 7, item 2).
Fig. 7: Rear of the temperature/humidity sensor
Key
2 CAN bus connection, 24 V
3 CAN bus connection, 24 V
The following CAN bus connection cables from the
CMC III accessories can 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)
The software is updated, if necessary, after being con-
nected. The status LED of the temperature/humidity
sensor glows blue throughout the entire update process
and also flashes purple while the sensor itself receives
an update.
In addition, the status LED of the CMC III Processing
Unit flashes white and a corresponding message ap-
pears on the website.
The update of the sensor is complete when the following
conditions have been fulfilled:
1. The LEDs on the CAN bus connection of the sensor
light green.
2. The multi-LED of the sensor behind the front panel
flashes blue and green, yellow or red, depending on
the condition 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 temperature/humidity sensor (fig. 7, 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 temperature/humidity sensor
flashes blue continuously.
 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.
Note:
No settings can be modified as long as the
update process is running.
Note:
The multi-LED of the temperature/humidity
sensor lights red continuously for approx.
5 seconds while the average value of the
temperature is being determined.
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 is disconnected from the mains power
supply and protected from damp and dust.
7.2 Disposal
Since the temperature/humidity sensor consists mainly
of the "housing" and "circuit board" parts, the device
must be passed on to the electronic waste recycling
system for disposal.
