Procedure
3.1 Unpacking and Checking the Material
Do!
Tip risk! This equipment has a high center of gravity without all units installed.
Secure the equipment before opening the door.
This section contains information on unpacking and checking the material.
The RBS 3107 cabinet is transported in a crate.
Note: Maximum cabinet weight is 350 kg (excluding batteries).
1. Examine the packaging for damage. If it has been damaged, then
immediately inform the transport company.
2. Check that the items delivered correspond to the packing list. For more
information, see Site Installation Documentation
3. Unpack the cabinet.
Note: Allow the cabinet to remain on the pallet until required for
installation.
4. Dispose of the crate in accordance with local regulations.
3.2 Positioning and Anchoring the Cabinet
Note: Before installing the cabinet the site must be prepared for routing
cables. All external cables, such as antenna and transmission cables,
are installed from below, that is, through openings in the bottom of
the cabinet.
To attach the cabinet to the existing base frame, do the following:
Note: The lifting device must be capable of lifting at least 400 kg.
1. Ensure that all packing is removed from the cabinet.
2. Unscrew the five bolts under the upper edge of the cabinet, as shown in the
figure below, using a hexagon 6 mm bit and a ratchet wrench.
3. Pull the cabinet roof a few centimeters towards the cabinet door, then lift it
straight up.

Installation Instruction
Figure 3 Roof and Cabinet Attachment
4. Screw the four M12 eyebolts into the top of the cabinet, as shown in the
figure below. Tighten them finger-tight.
Figure 4 Eyebolt Attachment
5. Attach lifting straps to the eyebolts and lift the cabinet.
Note: The angle of the lifting strap at the hook must not be more than 90
,
as shown in the figure below. (This is equivalent to the angles
between the lifting strap and the cabinet roof being at least 45
.)
6. Position the cabinet and lower it into the place for installation.
Note: Ensure that cabinet is level in all directions.
8
1/1531-COH 109 2073 Uen H 2006-11-06
Procedure
Figure 5 Cabinet Lifting
7. Remove the lifting straps and eyebolts.
8. Insert four washers and M16 locking bolts and tighten them to the
appropriate torque (depending on the material to which the cabinet is
attached), using a torque wrench and a 24 mm Open-ended head.
9. Attach the roof by pushing it straight backwards. Screw in the five bolts
and tighten them to a torque of 8 Nm, using a 6 mm hexagon bit and a
torque wrench.

3.3 Earth Grounding the Cabinet
Do!
Products not connected to ground risk being damaged by overvoltage or
overcurrent. Always connect products to ground according to instructions.
For general information about earth grounding principles, see Grounding
Guidelines for RBS Sites.
For information about installing earth grounding, see Grounding Material
Installation Instruction.
To connect the earth grounding cable to the RBS 3107, do the following:
1. Remove the six screws holding the Distribution Frame (DF) in place, using
a T30 Torx screwdriver, and push it to the left as shown in the figure below.
10
1/1531-COH 109 2073 Uen H 2006-11-06
Procedure
Note: Ensure that the factory-installed cables attached to the rear of each
Overvoltage Protection (OVP) module are not loosened.
Figure 7 Earth Grounding Cable
2. Route the earth grounding cable from the site Main Earth Terminal (MET)
to the cabinet earth grounding point.
3. Remove the M8 nut and washer.
4. Connect the earth grounding cable according to the figure above. The
washer must be placed between the cable lug and the nut. Tighten the nut
to 15 Nm, using a torque wrench and a 13 mm socket.
Note: Do not put back the DF yet. The opening is needed for the installation
of the AC mains cable described in section Section 3.5 on page
16. Furthermore, both sides of the DF must be available during the
installation of transmission, alarm, and GPS solution cables. See
Section 3.7 on page 35, Section 3.9 on page 49 and Section 3.10 on
page 53.
3.4 Connecting the External Battery Backup (Optional)
This section describes how to connect external battery backup to the DC filter,
if external battery backup is used. The DC filter is located below the ACCU.

3.5 Connecting the AC Power
This section contains instructions for connecting the AC power.
Danger!
Electric shock risk. Avoid both direct and indirect contact with parts connected
to mains power as this is likely to be fatal. Switch off the mains power before
starting work.
Danger!
Improper electrical installation may cause fire or electric shock that is likely to
be fatal. Only a qualified and authorized electrician is permitted to install or
modify electrical installations.
Stop!
Do not install or modify AC or DC powered equipment unless you are a
qualified and authorized electrician. Improper installation work can seriously
damage the equipment.
1. Ensure the following:
That the AC power is switched off at the source.
That the AC mains switch and all circuit breakers on the Alternating Current
Connection Unit (ACCU) are in their OFF positions.
That all the switches on Power Distribution Units (PDU) are in their OFF
positions.
That the switches on the Battery Fuse Unit (BFU) are off.
That the DF is removed so that there is easy access to the power cable.
