Node B Installation Guide Version 5.0.0 Page 16 of 37 Precautions The following precautions and checks are applicable to all mounting types:- 1. Leave blanking plugs over all connectors until they have been connected to the appropriate cabling. These plugs are specially fitted to keep moisture and contaminates out of the unit. 2. Connectors have been manufactured to fit their specific cables. Do not modify or force connectors. 3. Check Site Plans for engineering approval. 4. Ensure that good ground resistance is available at the installation site (<2) 5. Do not attempt to install in rain. 6. In adverse weather conditions care should be taken before work commences. 7. Where the Node B is mounted in an outdoor application the fixings sourced locally should be stainless steel A2-304 or equivalent. Direct Wall Mounting Direct wall mounting requires the following materials:- 1. Drill template - supplied with Node B 2. 4off M8x55L Rawlok Loose bolt or equivalent eg. Hilti anchor bolts - locally supplied 3. Drill & Masonary Drill Bit Position template and drill holes through template at appropriate positions as marked. Ensure that the drill template position is vertical. Figure 6-4: Drill template Position drill template and drill 1000mm (39.4inches)

Node B Installation Guide Version 5.0.0 Page 19 of 37 Pole Mounting This section specifies a suggested pole mount scheme using Unistrut components, and equivalent system can be used where available more readily locally. The Unistrut system can as standard cater for pole diameters up to 10inch (250mm). To mount the bracket for a pole the following materials are required:- 1. 2 pieces of P1001Bx14" A2-304 Stainless Steel Unistrut™ 2. 4off P1007 - 5/16”-18 UNC channel nuts with springs from Unistrut™ - locally supplied 3. 4off 5/16” x 1” UNC – Hex Head Cap Screw - Unistrut™ PN: HSHS031100EG or equivalent - locally supplied 4. 4off 5/16” – Plain washer Stainless Steel - Unistrut™ PN: HFLW031EG or equivalent - locally supplied 5. 4off 5/16” - Lock washer Stainless Steel - Unistrut™ PN: HFKW031EG or equivalent - locally supplied 6. 2off Cush-A-Clamp Sets (2-6inch) or U-Bolt Series (< 12inch)– see Unistrut™ catalogue The following diagram illustrates the installation using the Unistrut method:- Figure 6-7 : Pole Mounting using Unistrut systems Note: Where a Node B is required to be mounted to a pole greater than 10inch or to an irregular shaped mast eg. Hexagonal, banding may required to be used. In this situation contact your IPWireless field support for guidance.

The following mounting materials are required to secure the bracket into a rack. The figure below illustrates a typical installation, rack not shown. 1. Plate (9U x 19inch shown) or U-channels to mount the bracket onto standard 19" or 23" 2. 4off M8x20 Hex Head Cap Screw + 8off M8 Plain washer + 8off M8 Lock Washer + 4off M8 Nuts 3. 8 off Cage nuts + Screws – note these are required to secure the plate to the rack (not shown) Figure 6-8 : Node B - Rack Mounted Node B Bracket M8 Fixings – - Hex Head Cap Screw - Lock Washer - Plain Washer 2off - Nut 19inch 9U Plate
Node B Installation Guide Version 5.0.0 Page 21 of 37 Physical Installation of the Node B This section describes the installation of the Node into the mounting bracket and the connection of the power and interface cables. Step 5 Conduit Installation & Cabling Where the Node B is installed into an outdoor installation all power and IUB cable must be routed to/from the Node B via conduit. Where the Node B has to be connected to an outdoor installation of an INC conduit is required between the INC and power source. (Refer to the INC Installation Guide) Power and Ethernet cables are to be pulled through the conduit, one power cable and one Ethernet (or E3, T3, E1, or T1) cable(s) for each Node B. Where external alarms are to be utilized conduit shall also be necessary between the external alarm device and the Node B for monitoring the alarm. The cables need to be fed through the conduit and into the Node B via the cable glands (supplied) excess cable left for termination. Leave a sufficient loop of cables to enable them to be prepared back to the appropriate length. The figure below illustrates a typical conduit installation. Figure 6-9: Flexible Conduit Flexible conduit
Node B Installation Guide Version 5.0.0 Page 22 of 37 Step 6 Node B Installation onto Mounting Bracket This section describes how to mount and secure the Node B to the mounting bracket. The figure below illustrates the following steps 1. Align the top long dowel pins with top holes in bracket. 2. Insert Node B into the bracket 3. Ensure all dowels are inserted, if not repeat 1 & 2 4. Lower Node B into the keyslots 5. Secure Node B to bracket using 4 x M8 bolts & washers provided. Figure 6-10: Node B onto Mounting Bracket INSERT Node B Onto Bracket Once inserted LOWER Node B Secure Node B using M8 bolts + washers each corner
Node B Installation Guide Version 5.0.0 Page 23 of 37 Step 7 Ground Installation The main Node B ground cable shall use a minimum #2 AWG (Diameter 6.6mm or CSA 33mm2) stranded wire or equivalent earth braid. The ground cable is terminated on the Node B using terminal that shall fit the M10 (7/16”) bolt provided. The ground bolt can be position on either side and/or rear of the Node B. The grounding wire is terminated onto the site grounding ring. It should be noted that each site shall be designed for specific site, country or local installation requirements. CAUTION: Ensure that the earth braid or cable is bonded to a common earth with equipment that is co-located with the Node B.
