2 Safety instructions
EN
2 Safety instructions
2.1 General safety instructions
Please observe the following general safety instructions
for the installation and operation of the system:
– Assembly and installation of the door control module,
especially wiring with mains power, may only be per-
formed by a trained electrician.
– Please observe the valid regulations for the electrical
installation of the country in which the door control
module is installed and operated, and the national reg-
ulations for accident prevention. Please also observe
any internal company regulations, such as work, oper-
ating and safety regulations.
– Use only original Rittal products or products recom-
mended by Rittal in conjunction with the door control
module.
– Please do not make any changes to the door control
module that are not described in this user manual or in
the associated assembly and operating instructions.
– The operational safety of the door control module is
only warranted if used properly for the intended pur-
pose. The technical specifications and limit values
stated must not be exceeded under any circumstanc-
es. In particular, this applies to the specified ambient
temperature range and IP protection category.
– The door control module must not be opened. It does
not contain any parts that need servicing.
– Operating the system in direct contact with water, ag-
gressive materials or inflammable gases and vapours
is prohibited.
– Other than these general safety instructions, ensure
you also observe the specific safety instructions when
carrying out the tasks described in the following chap-
ters.
2.2 Operating and technical staff
– The mounting, installation, commissioning, mainte-
nance and repair of this unit must only be performed
by qualified mechanics and electricians.
– Only properly instructed personnel may work on a unit
while in operation.
2.3 Safety instructions on the door control
module
When operating the door control module, in addition to
the general safety instructions, please also observe the
following device-specific instructions:
– No extinguisher system should be used in the IT rack.
The IT rack loses its protection category as a result of
the door kits, and the functions operate counteractive-
ly. If an extinguisher system were to be used in the IT
rack, the doors would need to be closed, but this can-
not be guaranteed in conjunction with the door control
module.
– The door control module does not monitor the status
of the door (open/closed): We recommend installing
access sensors (DK 7030.120) on all doors. The sen-
sors can be connected to the CMC III system and re-
port the status of the doors.
– Make sure there is sufficient distance between the au-
tomatically opening doors and other components, so
as to prevent the risk of crushing injuries.
– This is particularly true when using your own tasks to
open the doors: First, please ensure that the task
functions correctly with the doors open. In the event of
a malfunction, this will prevent the enclosure doors
from buckling due to activation of the door kit exten-
sion.
– Take care to ensure that the doors are not closed
again until after the malfunction has been rectified (e.g.
after adequately lowering the temperature inside the IT
rack).
– It must be possible to manually open the doors of the
TS IT rack at any time with the aid of a door switch, a
door comfort handle or a reader unit. This is not nec-
essary for VX IT doors with ADO (Automatic Door
Opening) / vent flaps.
– In the event of a failure in the power supply and deac-
tivation of the magnet door kit or VX IT ADO vent flaps,
the doors of the TS IT rack will open automatically. By
means of a suitable alarm configuration in the CMC III
PU, ensure that the requisite protective measures for
the components installed in the IT rack have been ini-
tiated.

5.4 Electrical connection
5.4.1 Details concerning the electrical connec-
tion
The device is not de-energised until all of
the voltage sources have been discon-
nected!
Note:
The CMC III Processing Unit or Processing
Unit Compact must contain the software ver-
sion ≥ V 3.15.80. This means that the door
control module (DK 7030.501) automatically
receives the necessary software update via
the PU. This is the only way to guarantee the
function of the unit.
Ensure the correct allocation of all compo-
nents to the front door (door 1 – connections
6, 7 and 11) and rear door (door 2 – connec-
tions 5, 8 and 12).
An external signal at the alarm input will al-
ways impact both the front door and the rear
door.
Via the CMC III PU website, it is possible to
configure which door is opened when an ad-
missible access authorisation is entered on a
connected CMC III reader unit (transponder
card or numerical code) (see section 6.7.1
"KeyPad").

Depending on the door type, connect the relevant
magnet door kit to the front door (fig. 9, item 7) and
the rear door (fig. 9, item 8).
As an option, VX IT doors with ADO / vent flaps can be
tied.
Connect a power supply unit to the power supply con-
nection of the magnet door kit (DK 7030.060) (fig. 9,
item 14). Use the same voltage supply for this power
supply unit as for the components you wish to protect
(e.g. server).
Use one of the enclosed 2-wire cables for wiring. This
cable must not be shortened.
Connect the external temperature sensor to the door
control module connection at the rear (fig. 9, item 9)
and route the measuring sensor to the required meas-
uring point.
Finally, the installed magnet door kit / VX IT doors with
ADO for the front door and rear door must be activat-
ed on the CMC III PU website (see section 6.6.3 "Door
Opening").
5.4.3 Connecting the door kit extension
When using a climate control application such as a
Liquid Cooling Package, an underpressure will be creat-
ed in the TS IT racks which prevents the doors from be-
ing opened in isolation. In such cases, the additional
door kit extension is used, and presses against the door
of the TS IT rack from the inside with the aid of a spindle.

Connect a further power supply unit to the power sup-
ply connection of the door kit extension (DK 7030.060)
(fig. 9, item 14).
If an A+B power supply is operated in the IT enclosure
for the servers, one power supply unit must be con-
nected to supply circuit A and one to supply circuit B.
Once again, use one of the enclosed 2-wire cables for
wiring. This cable must not be shortened.
Next, join the two power supply units together using
the unused connections on the power supply (fig. 11).
Once again, use one of the enclosed 2-wire cables for
wiring. This cable must not be shortened.
Finally, the installed door kit extension for the front
door and rear door must be activated on the
CMC III PU website (see section 6.6.3 "Door Open-
ing").
5.4.4 Optional add-on components
If applicable, connect e.g. the signal output of a fire
alarm system or building control system to the alarm
input (fig. 9, item 4) .
If applicable, connect a door switch or door comfort
handle with opener function for manual opening of the
front door (fig. 9, item 6) and rear door (fig. 9, item 5).
If applicable, as an alternative to a door switch or door
comfort handle with opener function for access con-
trol, connect a suitable CMC III reader unit (coded lock
or transponder reader) for manual opening of the
doors (fig. 9, item 10).
5.4.5 Connecting the door control module
Generally speaking, it is possible to operate the door
control module without a CMC III Processing Unit (see

6.3 LED displays
A multi-LED for status display (fig. 13, item 2) and the
LEDs for displaying the target/limit temperature (fig. 13,
item 3) are integrated into the front of the door control
module. Further LEDs are located at the rear on the CAN
bus connection (fig. 14, items 15 and 16).
6.3.1 Multi-LED displays
The multi-LED indicates the status of the door control
module and the connected components.
6.3.2 LED displays for target/limit display
When operating the door control module without a
CMC III Processing Unit, the set temperature limit at
which the doors should open can be read from the tar-
get/limit value display LEDs. The LEDs are only illuminat-
ed in setting mode (see section 6.5 "Operation of the
door control module without a CMC III Processing
Unit").
6.3.3 LED displays on the CAN bus connection
A red and a green LED are located on the CAN bus con-
nection. They display the status of the CAN bus.
Note:
For operation, the door magnets (door kits)
and the VX IT doors with ADO / vent flaps
must be treated in the same way; both sys-
tems operate with magnetic locks. For VX IT
doors with ADO, only the vent flaps are
opened.

6.4 Acknowledging messages
There are generally three ways of acknowledging mes-
sages:
1. By briefly pressing the "C" button on the door con-
trol module. This confirms all alarm messages simul-
taneously.
2. By selecting a message with the right mouse button
in the message display and clicking on the "Ac-
knowledge Alarm" or "Acknowledge Devices" entry
with the left mouse button in the context menu.
If an alarm message has been selected, "Acknowl-
edge Alarm" only confirms the currently selected
message.
If a message concerning a configuration change has
been selected, "Acknowledge Devices" confirms all
related messages jointly.
3. By clicking with the right mouse button on a compo-
nent entry in the configuration area and clicking with
the left mouse button on the "Acknowledge Alarms"
or "Acknowledge All Devices" entry in the context
menu.
This can be used to confirm pending alarm messag-
es for that particular component or all configuration
changes.
6.5 Operation of the door control module
without a CMC III Processing Unit
If the door control module is not connected to a CMC III
Processing Unit, the door may also be opened automat-
ically by means of suitable settings directly on the door
control module. Here, the operator may choose be-
tween three target/limit temperatures: 30 °C, 35 °C and
40 °C.
Press the "C" button on the door control module and
hold it down for approx. 3 seconds until all three LEDs
for the target/limit value display on the front are perma-
nently illuminated.
The door control module is now in setting mode.
Briefly press the "C" button until only the LED for the
required target/limit temperature is illuminated.
If the "C" button is not pressed for more than 3 seconds,
the currently set target/limit temperature will be accept-
ed and the LED is extinguished.
Furthermore, automatic opening of the doors may be
activated via the alarm input. For this purpose, no further
configuration is required after connecting a suitable sig-
nal.
6.6 Operating via the CMC III Processing
Unit website
After logging on to the CMC III Processing Unit, the web
interface for operating the device is displayed.
First select the "CMCIII-DCM" entry in the navigation
area.
Similar to the CMC III Processing Unit, the Configura-
tion tab can be used to individually configure the access
rights for the door control module (Device Rights but-
ton) and the alarm messages (Alarm Configuration
button).
The Observation tab is used to configure all settings for
the door control module, such as the limit values for
warning and alarm messages. The following settings
may be made at the individual levels:
– "Device" level: General settings concerning the door
control module.
– "Temperature" level: Limits of the external temperature
sensor.
– "Door Opening" level: Settings for the built-in compo-
nents such as door magnets / VX IT doors with ADO,
spindles etc., and for opening the doors
– "KeyPad" level: Settings for a connected door handle.
Only editable parameters are described in the following
sections 6.6.1 "Device" to 6.7.1 "KeyPad". There are
also display values that provide information.
6.6.1 Device
General settings for the door control module are config-
ured at the "Device" level.
