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 TS IT
rack. The TS IT rack loses its protection category as a
result of the door kits, and the functions operate coun-
teractively. If an extinguisher system were to be used
in the TS IT rack, the doors would need to be closed,
but this cannot 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 (7030.120) on all doors. The sensors
can be connected to the CMC III system and report
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
TS 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.
– In the event of a failure in the power supply and deac-
tivation of the magnet door kit, 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 in-
stalled in the TS IT rack have been initiated.
