Consider the following points: a. Locate the terminal inside the building as close as possible to cable entrance. b. Locate the terminal on a firm mounting surface where it will be accessible to the technicians at all times; where it can be reached without a ladder; and where it will not project in a hazardous manner. c. Observe caution when exposing the terminal to chemicals in liquid or vapor form as they may damage the plastic components. Back of terminal: Wall-mounting keyholes 2.5 Remove the jumper wire retaining ring from the poly bag and install in the faceplate. 3.0 Feeder Cable Preparation and Strain Relief 3.1 Feeder cable diameters for the 3M Indoor Building Entrance Terminal (IBET) 4688V Series Min. Diameter Max. Diameter Entrance Cable 0.42" (10.7 mm) 1.45" (36.8 mm) If the cable diameter is smaller than the minimum, use Scotch Linerless Rubber Splicing Tape 130C to build up to the minimum. c Caution Avoid locations near flammable materials, ignitable gases, dust, moisture, temperature extremes, moving machinery, electric light and power circuits, and electrical equipment.
4 February 2017 78-0013-6127-4-B 3.2 Run the feeder cable 24" (610 mm) past the 3M Indoor Building Entrance Terminal (IBET) cable entry port. 25-50 pair 3.3 Slide the 3M Pull N Shrink Tubing (PST) on the end of the cable with the pull-tab away from the 3M IBET and temporarily keep it out of the way. 3.4 With the groove toward the 3M IBET and long end toward the cable, snap the cable gland halves around the cable. Slide the gland into the entry port of the 3M IBET. 3.5 Measure 2" (51 mm) of sheath past the gland inside the 3M IBET. Pull the gland and cable out of the 3M IBET. 3.6 Remove the sheath, leaving at least 21" (533 mm) of free conductor length. Identify and secure the cable groups ends. Bond the cable shield according to your company s practice. 3.7 Insert the gland s groove into the cable port. Slide the 3M Pull N Shrink Tubing (PST) over the gland and slowly unwind the core. The PST tubing fits over either the small diameter of the 25 to 50-pair gland or butts up against the 3M IBET 4688V for the 100-pair gland. 3.8 Complete the PST core removal over the gland. 3.9 The blank plate MUST be used in the empty cable port for UL Listing. 3.10 Attach the cable to the wall according to your company s practice. 100 pair 4.0 Terminal Grounding 4.1 Fasten a #6 AWG wire to the ground bar, which is located on the front of the unit. Connect other end of the ground wire to local ground per company standards. Note: Failure to properly bond and ground the terminal per N.E.C. or local equivalent codes may render protection arrestors useless. 5.0 Splicing 5.1 Splice the feeder cable group(s) to the appropriate terminal block tail(s) per your company s practice. 5.2 Bundle the completed splice module(s) and secure them with 3M Cable Ties within the splice chamber. 5.3 Close the splice chamber cover and secure the lock plate bolt. 2"
78-0013-6127-4-B February 2017 5 6.0 Installing the Electrical Protectors Note: Use ONLY UL Recognized or Listed protectors in the 3M Indoor Building Entrance Terminal (IBET). 6.1 The 3M Indoor Building Entrance Terminal (IBET) 4688V uses a standard five pin protector receptacle field. The long pins of the protector connect Tip and Ring from the feeder cable though the protector to the short pins to the distribution/house wire. 6.2 Insert protectors into the protector receptacle field according to your company s practice. 8.0 Multiple 3M Indoor Building Entrance Terminal (IBET) 4688V Series Installation Use this application when the required cable pair capacity exceeds the capacity of a single 3M IBET. 8.1 The design of the splice chamber and the grooved cable glands make it possible to stack the 3M IBET vertically, up to three of the same cable pair count and within the diameter limits in the chart in 3.1. 8.2 Mounting the 3M IBET a. Mount the 3M IBET bodies using the cable glands to position them. b. Assemble the feeder cable strain relief according to Section 3.0 and prepare the feeder cable so that 21" (533 mm) of free conductor length will be in the last IBET. 6.3 To disconnect the distribution wire, pull the protector out to the detents on the long pins to hold it in place. This continues to protect from the feeder cable side. 7.0 Protective Cover 7.1 With the cover closed, the exposed hasp allows for locking when security is required. 1" (25 mm) minimum 21" (533 mm) 2.75" (70 mm) minimum Note: 3M Indoor Building Entrance Terminal (IBET) 4688V 50/25 shown. All 4688V terminal sizes will stack as shown in detail above.
8.3 Place cable glands around the free conductors and position into the 3M Indoor Building Entrance Terminal (IBET). 8.4 Separate the feeder cable pair assigned to each 3M IBET; splice and bond the 3M IBET according to section 4.0 Terminal Grounding. 3M, Scotch, MS 2 and Scotchlok are trademarks of 3M Company.
