Secure Anchor Stakes to cabinet with the 3/8" x 1" bolts provided. See Figure 34. Figure 34. Slide slab sections into place. Insert four slab mount bolts (not included) trough the Angle Irons and thread loosely into slab sections. Drive Anchor Stakes so Angle Irons are flat on the slab. Tighten all mount bolts securely.
E. Cable Preparation Remove cable jacket(s), shield and core wrapper this mark. Feeder cables terminated in the cabinet will be secured NOTE: If cables are to be sealed against moisture, a just per standard procedure at the center of the Bond Bar. sheath opening so that top of end seal is flush with top of If Feeder Cable is to loop through, secure Cables as Bond Bar. Bond Straps should be long enough to project close together as possible at the center of the bar.
III. P edestal Cabinet Cable Routing A. MS 4065 (300-Pair) Cabinet Pairs to be terminated must run through the grommeted holes in Hinged Panel. Form a .6 m (2 ft.) gooseneck behind Panel to allow for slack. See Figure 37. The loop through cable (express pairs) should be taped or wrapped and secured to rear of cabinet.
IV. P ole-Mount Installation and Preparation A. MS 4065 (300-Pair) with 4098 Conversion Kit Pole-Mount Conversion Kit a. Remove front Skirt and Hinged Panel for easy access. b. Locate Cabinet in desired position on pole per Figure 40. c. Assemble A1, A2, and A3 to Top Pole-Mount Bracket and tighten. d.
B. MS 4094 (1200-Pair) and 4095 (1800-Pair) Pole Mount Installation: Mount cabinet in desired position on pole using hardware included. Follow standard procedure. See Figure 43. Cable Installation: a. Cables should enter cabinet through ports directly in line with appropriate module frame. If only a single cable is to be terminated, place cable in center port to provide the best protection for the cable.
b. Cabinet Venting To close vents and eliminate air circulation, turn blank side of plastic vent toward louver plate. To open vents for maximum air circulation, insert plastic vent with screened side toward louver plate. c. MS 4064 Terminal Block Bracket This Bracket will accommodate two 3-pair protected or unprotected terminal blocks in the MS 4065 Cross-Connect...
B. Identification of Feeder and Distribution Modules Feeder Modules (MS 4010E) have green covers. Distribution Modules (MS 4011E) have blue covers. C. Cables Entering From Top of Polemount Cabinet Lay all binder groups to be terminated inside ‘U’ Frame Channel. Figure 51. Module Mounts are used in sets of left and right. They are marked with an “R”...

When Base is filled, check wiring order with the 4052 Check Comb. See Figure 57. Figure 57. i. Place Module Body/Cover assembly into leaf springs of Splicing Head, with 3M logo in lower left hand corner and black marks toward Head wire guides. See Figure 58. Figure 58.
Crimping: a. Put crimping clamp on Splicing Head; hose can be either to left or right. Pins on inside edge nest in pin pockets on Splicing Head when clamp is placed at an angle on head. See Figure 59. b. Rotate clamp until detents lock clamp in upright position.
4061 Cable Separators are used between modules and where frames are “open” to close off Feeder or Distribution binder groups in the 3M MS Cross-Connect Frames. 2. The Cable Separators are supplied in sheets of four. To remove a single Separator from the sheet, snip along the notched section as shown in Figure 63.

2. Insert Attachment Tabs to module mount on underside. See Figure 67. Figure 67. 3. Mount module and snap Module Protector over face of module. See Figure 68. Figure 68. 4. Identify pairs by marking on the matte-finished cover with an indelible marking pen. See Figure 69.
F. Tapping Cables that are looped through may be tapped by using two Bodies in the Cross-Connect Feeder Module termination. See Figure 71. Electrical connection is made as the bodies are crimped, before the wires are cut. Tapping a Non-Working Feeder Cable: a.
VI. Jumpering Jumper wires must be plastic-insulated .5 mm (24 AWG) g with a maximum O.D. of 1.1 mm (.042 inches) to insure reliable connections with multiple insertions. See Figure 75. Figure 75. A. Running Jumper Wires Pull wire from spool to either Feeder (green cover) or Distribution (blue cover) Module.

C. Half-Tap Jumpering The MS 4055 HT Half-Tap Jumpering Tool is used to make cuts or cable transfers within a cross-connect box. The 4055 HT Tool (orange to distinguish it from the 4055 Impact Insertion Tool) allows a jumper wire to be punched into the contact of a Cross-Connect Module (MS 401 OE 4011 E) but does not cut off the end of the wire as is done...
D. MS 25-Pair Probes 4048 25-Pair Probe a. The MS 4048 25-Pair Pocket Probe is designed to make an electrical contact to each wire in all types of 25-Pair MS Modules. The 4048 Probe should be inserted into test entry ports ONLY. These are the holes at mid-level of Module.
E. Pair Test Plug 4047 Pair Test Plug makes electrical connection from terminal block to module contacts. Insert pins of plug into test ports in mid-level of Module. See Figure 93. Slide catch forward over module cover to hold plug in place. Attach alligator clips from test set to terminal block.
A. Splicing Head Detail (See Figure 97). Wire guides, pair splitters, and retainer springs are coated with an electrical insulation. Tape plate is plastic. B. MS Air/Hydraulic Crimping Unit (See Figure 98). Description-Pump can be operated either by foot or hand. An air cylinder or compressor with an output pressure of 6.3-7.0 Kg/cm2 (90-100 Psi may be used as source.
