ICON 3RU rack frame
1Introduction
The Pro-Bel 1050 rackframe is a 19 inch wide 3U high unit, which can accommodate
a wide range of ICON modules. Modules may have either a 20mm or 30mm rear
connectors. This helps achieve a balance between the total number of modules and
connector space for each module.
The main features are:
•accommodates up to 17 modules with 20mm rear connectors or up to 12
modules with 30mm rear connectors or a mixture of the two widths
•hot-swappable dual power supplies
•alarm outputs for power supply and fan failure
•compatible with Pro-Bel COSMOS configuration and status monitoring
system
•removable door
•robust construction
•fan assisted cross flow cooling

2Installation
2.1Installing the rackframe
Since the 1050 3U rackframe is designed for transverse air flow, it is not necessary to
leave vertical space between multiple frames. However, the rear and side vents must
not be obstructed.

2.2Door fitting and removal
The ICON door is held closed by sprung ball latches at either side. The door is
opened by pulling outwards using the orange coloured finger pull recesses at the
top.
The door can be removed from the frame by opening it approximately 30° and lifting
upwards. It will not disconnect from the hinge at a greater angle. To re-fit the door,
ensure that it is located centrally on the hinge.
2.3Frame designation
A frame designation label may be fitted to the door label window to help identify the
installed modules in larger systems. The label can be created by printing the
required text onto a suitable material such as acetate using a laser printer. A
Microsoft Word template ‘3U Frame Designation Label’ is available on the Pro-Bel
web site at www.pro-bel.com in the support/documentation section
The label is simply inserted into the slot in the rear of the door.

2.5Module Installation and removal
Step 1. Fit the rear connector:
•ensure plastic latch is fully retracted
•slot the rear connector ‘locating guide’ into the appropriate locating holes
then push the latch fully home
Step 2. Fit the module:
•slide the module along the guide rail of the required slot, gently pushing
it fully home until it marries up with both the rear connector and power
and status monitoring bus connectors

Step 3. Fit the module locator
On the 1050 3U frame, the card guides and rear connector fitting holes use 10mm
spacing. However modules can only be fitted at 20mm and 30mm spacing, as
determined by the chosen rear connectors.
To ease the fitting and removal of modules, once 20mm and 30mm rear connectors
are installed for each rack’s complement of cards, module locators may be fitted.
The locators snap-in to 10mm spaced holes underneath the board guides.
WARNING: Always fit the rear connector before inserting the module. Fitting the rear
connector after the module is inserted may damage the connector.
Notes:
Certain modules with tall components may not fit to the left hand side of a module
with a 20mm rear panel. Please check before fitting the rear connector panel.
Cover unused rear panel space with the blank rear panels supplied.
Module removal
To remove the card proceed as follows:
•lift up the card ejector and gently pull the card out
WARNING: Do not remove the rear connector with the module in place, as rear
connector pins may be bent or damaged.
WARNING: Please ob serve nor mal static han dling pre cau tions when han dling
elec tronic equip ment or sub assemblies.

2.6Inserting and removing power
supplies
The 1050 3U ICON frame accepts both main and redundant 1950 universal power
supplies which autosense input voltage between 90 and 253 volts and 50-60 Hz.
The power supply integral fan provides cooling for itself and all modules. There is
an 80mm deep space between the front of the modules and the door to allow the
cross flow cooling air to reach each module. However, the front door must be kept
closed for this cooling to function.
The adjustments on this power supply unit are set at the factory and should not
require re-adjustment.
Power supply insertion for the 1050 3U frame involves the following steps:-
•slide the 1950 power supply into one of the available slots at the left of
the 1050 frame using the top and bottom PSU guides
•tighten the captive screw at the rear of the frame
•insert mains cable
•repeat for the second power supply
•ensure front door is closed
•if only one PSU is fitted, use the left hand slot to encourage good air-flow

Warning: When dual power supplies are used, there will be two mains cables. To
remove risk of shock remove both cables before servicing.
Power supply removal is as follows:
•remove mains cable
•loosen the retaining screw at the rear of unit
•slide out the power supply from the front
Repeat as necessary
Note: It may be necessary to remove a blanking plate covering the inner mains
connector opening. To do this remove any adjacent rear connector panel, loosen the
PSU retaining thumb screw and withdraw the blanking plate through the connector
panel space.

2.7Power supply monitoring
The status socket at the rear of the 3U frame allows the status of the 1950 PSU to be
monitored remotely. Relay contacts indicate errors in DC output voltage, fan
operation or over temperature for each power supply. Relay 1 is fitted on PSU 1 and
relay 2 is fitted on PSU 2.

Insertion involves the following steps:
•remove any blanking panels by loosening the two captive screws
•carefully align the 1250 COSMOS controller with the internal guides and
gently push it fully home
•tighten the two captive screws
•removal is the reverse of insertion
A single controller may be fitted in either slot. If two cards are fitted, they will
provide a dual redundancy role. Both controllers may be connected on a single
CANbus network or each may be connected to completely independent networks.
Two loop-through RJ45 connectors are provided on each 1250 controller and may be
wired using CAT5 UTP cable.
The connections are as follows:
If shielded cable is preferred, the RJ45s on the 1250 are of a screened type and a
ground contact can be made to the mating connector screen.
For more details on COSMOS please refer to the COSMOS manual.

•check that the mains is connected
•check that the fuses are intact
Note that the 1950 power LEDs are visible through apertures in the door. In normal
operation, they should illuminate green.

Power supply indicators change from green to red
If the 1950 dual colour LED changes to red then a fault condition exists and a
replacement unit should be obtained. A red LED indicates that one of the following
conditions is present:
•voltage rails under or over voltage
•fan defective
•unit is over heating
In the event of a failure of one power supply the second unit will continue to supply
the modules in the rack. In addition, the working unit will power the fan of the
defective unit to prevent air flow obstruction. A replacement unit should still be
obtained as soon as possible.
Power supply operation is also monitored via the Pro-Bel status monitoring system,
please refer to the COSMOS status monitoring manual for details.
The rear connector of the power supply provides the following voltages to each card
in the frame:-
