Unicab-Vario
Outdoor Active Cabinet
Description
Features and Benefits
The Unicab-Vario cabinet is a
double-walled, weatherproof,
protective outdoor cabinet
that accommodates electronic
equipment, guaranteeing reliable
functionality.
• Maintenance-free surface made of
environmentally resistant plastic
The Unicab-Vario cabinet protects
components against the effects of
weather and extreme temperatures.
Applications
• Telecommunications: collocation,
xDSL, UMTS, cable television, DLC,
RSLU
• Electronics: measurement and
control
• Traffic control technology
• Constructed of recyclable materials,
the double-walled cabinet assures
optimum interior climate control
• Light-weight in comparison with
metal cabinets of the same size
and function
• Can be delivered completely
assembled or as a kit
• Passive or active cooling systems
available
• Flexible mounting arrangements
for components, meeting either
ETSI or 19-inch standards
• Installs over existing housing
and plinth providing economic
alternative to new builds
• Replacement of external housing
parts possible without interruption
of service
The housing consists of a metal inner shell with a plastic
outer shell made of fibreglass-reinforced polycarbonate. For over 25 years, this plastic has proven durable
in cross-connection cabinets for major communications
service providers around the world. The outer dimensions satisfy the international guidelines EN 301169-2.
The plastic roof (1) features a water-drip protection lip
on both the front and the back of the cabinet. Cabinets
can be installed side-by-side. On the sides of the roof,
there are small areas for customer-specified identification. Slots provide air exchange for climate control of
installed components.
The outer plastic shell (3) is fixed to the frame and can
be installed or removed part-by-part (side panels, back
wall, doors) without interruption of service.
• The outer surface of the doors and back are
vertically fluted, making it difficult to affix illegal
posters (3a).
• The doors have a 3-point locking mechanism and
can be held open. Available accessories include:
- Double or single locking mechanisms with
revolving handle for profile cylinders (satisfying
DIN 18252)
- Door contact sensors
• Hidden closing and locking elements make
vandalism difficult
• Removable front panel, locked from within, for
access to lower part of the cabinet (4b).
The inner structural frame (4) made of aluminium profile
rods, creates a closed metal inner shell when metal
shielding sheets (5), base plates (6) and shielding sheets
on the inside of the door (7) are installed.
Designed for installation of
- a frame (8) for mounting chassis (satisfies ETSI
standard ETS 300 199-4, as well as 19-inch standards)
- cable connection and distribution equipment for
both copper and fibre optic networks
• Mounting plates, frames or rails are available for
customer-specific solutions.
The base plate (6) protects the inner space against
moisture rising from the ground. It provides a sealed
feed-in area for underground cables.
Divides the cabinet into a component accommodation
area.
• (4a) above the base plate
• (4b) below the base plate, for the installation of buffer
batteries, as well as cable and plinth mounting elements
The base plate can be delivered either with cable
grommets or closed without cable entries. The closed
base plate is opened by the customer as required for
cable feed-in.

Dimensions
The plinth (9) is made of steel and the separation point
between the cabinet and the plinth is at just above ground
level. Support grids with large surface areas (10) distribute
the cabinet's weight over the bottom of the excavation.
Plastic sheets (11) cover the plinth's upper half. Cable
routing elements are available for guiding cables into
the cabinet and ensure that the minimum bend radius is
maintained. Cable conduit pipes can be connected over
a cable connection. Predetermined break-point elements
form the interface between the cabinet and the plinth
(12). These reduce the effect of accidents, since the plinth,
which is in the ground, usually remains undamaged. As
a result, expensive excavation work after accidents is
usually not necessary. Defective predetermined break-point
elements can be easily replaced. A steel carrier is available
for Unicab-Vario installations on concrete slabs or on
rooftops.
Environmental module (2)
Depending on the energy generated by the installed equipment and the temperature difference to the outside, the
cabinet's inner space will become warm. Without proper
ventilation, the temperature can exceed the permissible
ambient temperature for the installed equipment. This problem can be solved by use of a suitable cooling design. The
cabinet´s outer plastic shell is made of polycarbonate which
has excellent thermal insulation properties. This minimises
the heating effects of direct sunlight on the cabinet. Two
cooling methods are available, passive and active; both
methods protect the inner space from environmental hazards such as dust or water.
Options for climatisation
Fixed-line carriers all over the world are deploying active electronic equipment in external cabinets throughout
their distribution networks as they deliver advanced broadband data, voice and video services to their business
and residential customers.
Active equipment must be housed in a sealed environment regulating both temperature and moisture, which,
if not properly controlled, can seriously and adversely affect equipment reliability and service-life. Connectivity
such as cross-connect equipment also benefits from a controlled environment.
The Unicab-Vario cabinet offers a secure, customizable environment for housing both active and passive equipment, and support use of copper- and fiber-based technologies. Four options of cabinet climatisation are
available
•
•
•
•
Passive
Roof fan (forced aeration)
Heat exchanger
Air conditioner
All active climatisation devices are located in the cabinet roof, assuring easy retrofit and interchangeability of
devices.
The following must be considered when choosing the correct method of climatisation for a given installation:
•
•
•
•
•
What devices will be installed in the cabinet
What are the dimensions (height by width by depth) of each device
What is the maximum working temperature of each device
What is the power (heat) dissipation of each device
What is the maximum ambient temperature (without sun radiation) in the area of installation
Passive cooling
Active cooling
The energy given off by the active components warms the
inner metal shell. The cooler air circulating between the
inner and outer shells (chimney effect) leads the heat out
over the roof. To enhance the cooling effect and to avoid
hot spots, fans should be used to increase air circulation.
• No ingress of dust or humidity
• Plastic outer shell reduces influence of solar radiation
Heat is dissipated by placing a cooling device inside the
roof. This environmental module increases the dissipation
of heat.
