Mount 110A- or 110P-type terminal blocks on the wall

Return to Task List

The 110A-type terminal blocks can be stacked in almost any arrangement at any height or location on the wall. One arrangement is shown in 110A-Type Terminal Blocks (300-Pair). The distance between the mounting screw holes on the terminal blocks is 10.8 in. (27.4 cm). If a vertical patch cord trough is used, the distance between the mounting screw holes is 5.31 in. (13.3 cm).

With 110P-type terminal blocks, the first block of the trunk/auxiliary field is aligned with the left side of the system cabinet. See 110P-Type Terminal Blocks (900-Pair). This arrangement allows for growth on the right side of the MDF.

1. Route the cables from the rear of the cabinet stack to the MDF via the Cable Slack Manager. See Install Cable Slack Managers.


2. If you are installing 300-pair terminal blocks, draw a level horizontal line on the wall 47.5 in. (1.2 m) above the floor. See 110A-Type Terminal Blocks (300-Pair).
   
   If you are installing 900-pair terminal blocks, draw a level horizontal line on the wall 23 in. (58.4 cm) above the floor. See 110P-Type Terminal Blocks (900-Pair).


3. To mount the first trunk/auxiliary field terminal block, partially install 2 3/4-in. #12 wood screws, 7-11/16 in. (19.5 cm) apart on the left side of the horizontal line on the wall.


4. Slide the bottom terminal block ft onto the mounting screws and mark the upper mounting screw locations.


5. Remove the terminal block and partially install the upper mounting screws.


6. Place the terminal block on the mounting screws and tighten the screws.


7. If installing a vertical patch cord trough, partially install the first screw for the patch cord trough, on the line, 7/8-in. (2.2 cm) to the right of the previous screw. Partially install the second mounting screw 5.31 in. (13.5 cm) to the right of the screw just installed. Repeat Steps 4, 5, and 6.


8. If another trunk/auxiliary field terminal block is to be installed, partially install the first screw for the terminal block, on the line, 7/8-in. (2.2 cm) to the right of the previous screw. Partially install the second mounting screw 7-11/16 in. (19.5 cm) to the right of the screw just installed. Repeat Steps 4, 5, and 6.


9. If a horizontal patch cord trough is to be installed, install it, on the line, between the trunk/auxiliary field and the distribution field.


10. To install the first distribution field terminal block, partially install 2 3/4-in., #12 wood screws, 7-11/16 in. (19.5 cm) apart on the line, to the right of the vertical patch cord trough. Repeat Steps 4, 5, and 6.


11. If installing another distribution field terminal block, partially install the first screw for the terminal block, on the line, 7/8-in. (2.2 cm) to the right of the previous screw. Partially install the second mounting screw 7-11/16 in. (19.5 cm) to right of the screw just installed. Repeat Steps 4, 5, and 6.


12. If installing a vertical patch cord trough in the distribution field, repeat Step 6.


13. Repeat Steps 11 and 12 until all the terminal blocks and vertical patch cord troughs in the distribution field are installed.
