CHAPTER 1 About this document
1.1 Introduction
This document explains the procedures necessary to install the Nokia
Rooftop Wireless Router.
10 Nokia RoofTop™ Wireless Router Installation Guide
Nokia RoofTop™ Wireless Router Installation Guide 13
CHAPTER 2 Safety issues
2.1 Introduction
It is important, when installing the Nokia Wireless Router, that the unit is
not installed where it could be either damaged by its environment, or pose
a hazard for the user. In this respect, when installing the unit be aware of
the following Hazard Warnings and Regulatory Safety Requirements
14 Nokia RoofTop™ Wireless Router Installation Guide
2.2 Hazard warnings
•Environment - Do not place the Network Power Unit (NPU) in a
very cold, dusty, wet or high humidity environment. The unit should
be situated away from all heat sources such as radiators, heat
registers, stoves, amplifiers and other heat producing
appliances.
• Fire or electric shock - Do not expose the NPU to any type of
moisture, including rain. Do not use or install near water-related
environments such as sinks, bathtubs, laundry areas, spas, swimming
pools, or in wet basements. Take care not to spill any liquids on the
unit.
•Use extreme caution when installing antennas in areas with overhead
power lines. Outdoor antennas and their supporting masts, guy wires,
and cables are electrical conductors. Contact with high-voltage
electrical wires can cause serious injury or death.
•Because antennas and wireless routers are elevated metal objects with
connections to ground, they attract lightning. Attach a grounding wire
to the antenna and router to provide a safe path to ground for
lightning.
•Do not install the router near medical equipment or in a hospital or
medical environment without ensuring that there will be no
interference with such equipment.
•Persons with pacemakers should not go close to the router on the roof.
If you have any reason to suspect that interference is taking place
with a pacemaker, switch off the router immediately.
• Co-location - In certain situations, multiple wireless routers may be
co-located on the rooftop of a residential subscriber. To comply with
RF safety requirements, there must be a minimum distance of one
meter (either horizontally or vertically, depending on the rooftop
environment) between each wireless router. Wireless routers may not
be co-located with or work in conjunction with other transmitting
devices without professional installation.
•RF exposure - To comply with RF safety requirements, do not go
closer than 20 cm of the antenna on the roof when the Network/Power
Unit is plugged in.
Nokia RoofTop™ Wireless Router Installation Guide 17
CHAPTER 3 Planning the installation
3.1 Main installation steps
The complete wireless router installation consists of five basic steps:
1. The Nokia roofTop Wireless Router
2. The Multiwire connection (between the router and the Network/
Power Unit)
3. The Network/ Power Unit
4. The grounding (where required)
5. The indoor connections between the Network/Power Unit and the
computer(s) in the property.
18 Nokia RoofTop™ Wireless Router Installation Guide
When planning the installation the following needs to be considered:
•The hardware and tools required to complete the installation.
•Wireless router installation location.
•Multiwire routing between the router and the NPU.
•The power source location for the NPU.
•The routing path for the ethernet cabling.
•Antenna grounding and lightning arrestor requirements.
3.1.1 To find a location for the router
When planning the location of the router the highest point on the roof
should be used to ensure a clear line of sight. Existing structures like
chimneys, pipes, tv antenna poles etc. should be used for mounting the
router. Only if there is no suitable mounting point, should a mounting pole
be used.
Height of the antenna is often limited to physical limitations of the site.
For example, an antenna mast can be placed on a rooftop or installed on
an existing structure or tower. Avoid using a mast if at all possible, but be
sure that the antenna clears the roof line.
It is acceptable to use the TV antenna pole already installed. If the TV
antenna is used, be sure to loosen the antenna mounting, slide the TV
antenna down the pole leaving sufficient room to mount the router at the
top of the pole.
Nokia RoofTop™ Wireless Router Installation Guide 19
Main installation steps
3.1.2 To plan the Network/Power Unit location
The Network/ Power Unit can only be physically located by being
plugged into an AC outlet. When locating the AC outlet for the Network/
Power Unit consider:
•The route of the multiwire cabling
•The proximity of a telephone connection point (where applicable for
HomePNA) or routing of the Ethernet cable
3.1.3 To plan the cable routing
•Avoid pipes, downspouts and possible areas which may abrade the
cabling.
For further details see Chapter 6, Routing the cable into the property.
3.1.4 To plan the grounding
Test the existing grounding system at the property. Where the existing
grounding is not acceptable, consider:
•Route of the grounding cable from the router, avoiding other pipes,
down spouts etc
•Location for the grounding rod
20 Nokia RoofTop™ Wireless Router Installation Guide
Nokia RoofTop™ Wireless Router Installation Guide 21
CHAPTER 4 Outdoor installation

2. Attach the antenna by screwing it into the top of the wireless router.
Carefully guide the antenna down onto the RF pin to prevent the pin
being bent out of shape. Ensure secure connection, but do not
overtighten.
Attach the omni-directional antenna
24 Nokia RoofTop™ Wireless Router Installation Guide
3. Connect the multiwire connection to the D-Connector in the bottom
of the wireless router. Tighten the two screws on the connector and
slide the rubber sleeve over the connections to prevent the ingress of
water.
Attach multiwire connection and Ground wire
NOTE: Take care when tightening the D-Connector to the router. It is
easy to damage the router casing if the screws are overtightened.
4. Using cable ties and/ or adhesive tape, secure the multiwire
connection and ground wire (where used) to the mast. Take care to
avoid placing strain on the connectors when securing the cables to the
mast. Use ties/ tape about every two feet down the length of the mast.
Always cover the cable ties with electrical tape to prevent excess
pressure on the D-connector should the cable tie fail.
5. Attach mounting bracket to back of router. Ensure that the bolt fits
correctly and is not cross threaded. There is no need to tighten the
bolt, play is required to attach the router to the mast mounting
bracket.

7. Slide the router and its bracket onto the router mount. Make sure that
the router is mounted perfectly vertical on the mount, using a level as
necessary, and tighten the bolt in the back of the router. Be careful not
to overtighten the bolt. Overtightening of the bolt will strip the thread
in the back of the aluminum casting of the wireless router.
Slide the router mount onto the mast bracket
28 Nokia RoofTop™ Wireless Router Installation Guide
4.2.1 To prepare and install grounding
NOTE: Grounding is only installed where the existing grounding system
is not sufficient for router grounding purposes.
Because antennas are elevated metal objects with connections to ground,
they attract lightning.
Attaching an effective ground to the router provides a path for the
lightning.
1. Connect the grounding box connector marked “Surge” towards the
antenna and the connector marked “Protected” to the Network/ Power
Unit (NPU) end of the cabling.
2. Protect the connections as previously described, using
weatherproofing tape.
3. Locate the lightning arrestor close to the point of entry to the home.
4. Provide a good, very low resistance wire connection from the
wireless router to the ground.
5. Use #12 copper wire connected to the router grounding clamp and a
ground rod next to the building.

CHAPTER 5 Routing the cable into the property
5.1 General guidelines on cable routing
•Where possible, route the cables inside the wall/ roof spaces
•THINK where the cables are going to go! Avoid air ducts, water and
gas pipes.
•Try to use existing entries into your home to avoid having to drill
holes.
•Try to make the cable entry to the computer connections as close to
the your PC as possible, using the shortest cable possible.
•Where wires have to be routed outside of the building, make sure that
they are supported with cable clips at 18 to 24 inch intervals and are
not unsightly. Make sure that there is a “drip loop” at the point of
entry to prevent water ingress into the property. Seal any drilled holes
using silicone sealant.
