3.1.1 Important Safety Instructions (Please Save)

When using your telephone/telecommunications equipment,basic safety instructions should always be followed to reduce riskof fire, electric shock and injury to person, including the follow-ing:

A. Read and understand all instructions.

B. Follow all warnings and instructions marked on product.

C. Do not place this product on an unstable cart, stand or table: theproduct may fall, causing serious damage to product.

D. Slots and openings in the cabinet and the back or bottom are pro-vided for ventilation. To protect it from overheating, theseopeningsmust not be blocked or covered. This product should nev-er be placed near or over a radiator or heat register. This productshould not be placed in a built-in installation unless proper ventila-tion is provided.

E. This product should be operated only from the type of powersource indicated on the marking label.

F. Never push object of any kind into this product through cabinetslots as they may touch dangerous voltage points or short out partsthat could result in the risk of fire or electrical shock.Never spill liq-uid of any kind on the product.

3.1.2 Gathering Tools and Supplies

The following tools and supplies are required tomount the K04.

S Standard blade and phillips screwdrivers

S Portable hand drill and proper size drill bits

3.2 Mounting the Assembly

3.2.1 Drywall-Type Surface Installations

When installing the assembly to a drywall-type surface, place itagainst the wall in the desired location. Mark the left top andbottom hole locations to accommodate the wall anchors to beused. Next, open the 4-position mounting cover and locate andmark the mounting hole location. Remove the assembly fromthe wall and drill the appropriate size hole to accommodate thewall anchor being used.Donotmake the hole too large. The cor-rect size hole is obtained when the anchor fits snugly into thehole and against the wall.

Re-position the K04 against the wall and secure the top left cor-ner first then the top mounting position inside the 4-positionmounting assembly. Complete the installation procedures by se-curing the bottom portion of the backplate to the wall.

3.2.2 Solid Wood-Type Surface Installations

When installing the bracket to a solidwood-type surface (i.e. ply-wood backboard, etc.), the #10 size wood screws (supplied) canbe used. Place the assembly against the wall in the desired loca-tion. Install one wood screw into the left top hole location andone screw into the right bottom hole location of the backplate.Next, open the 4-position mounting assembly cover. Locate thetop right mounting hole and install the wood screw. Install thelast wood screw into the left bottom hole location of the back-plate to secure the assembly against the wall.

- NOTE -When installing theList 8 unit, remove the cover to provide easieraccess to the mounting screw locations.

3.3 Power Connections

Refer to Figure 3 through Figure 7 for wiring details.

3.4 Chassis/Frame Ground Connections

Agroundwire (#6 or larger) should be attached to the ground luglocated on themounting plate or 4-slot mounting. For cell site ap-plicationswhere theK04 is installed in a weather-proof enclosure,the K04 ground lug should be connected to the enclosure singlepoint ground bar that is then connected to the cell site groundgrid. Be sure to follow all local grounding practices and proce-dures that would apply for installing any mounting assembly.

Power connections, if required, are made to the the 3-positionterminal block (TB9) located inside the 4-slot mounting assem-

bly. Connect the ---48Vdc power wire to the “---” (red) screwterminal. Connect the other lead to the “+” (black) screw termi-nal. Connect the green wire to the Chassis Ground screwterminal. Westell offers a ---48Vdc, 1 Amp Wall Power Supply(Model WPS4810) that can be purchased separately.

3.5 Facility/Network Interface Connections

Facility-side wiring connections can be made to either a 66-typewiring block (List 1, 4, 7 or 8) or to screw terminals (List 5).

3.6 Customer Interface Connections

Customer-side wiring connections can be made to the 66-typewiring block (List 1, 7 or 8) to RJ48C/S modular jacks (List 4, 5or 8).

3.7 Module Installation

When all wiring is completed and secured, themodule(s)may beinstalled inside the assembly cover. Refer to the appropriatepractice for optioning and testing information for each module.When testing is complete and the circuit is functioning correctly,close and re-lock the cover (Except List 4 Option).

- CAUTION -Use care when installing and removing modules - do not forcea module into place. If a module resists insertion, remove itand check for obstructions in or near the module’s or shelf’sconnectors and mounting slots. The module may then becarefully aligned and gently re-inserted.
