(2) loosen adjustable lug until it will slide completely free, without touching the exposed wire. (3) when adjustment point has been selected, retighten lug only enough to assure a firm contact, do not tighten beyond this point. failure to follow these three steps in order can result in damage to the resistor. mounting hardware options 101, 204, 301 101, 203, 301 101, 203, 301 101, 203, 301 101, 203, 301 102, 206, 303 102, 206, 303 102, 206, 303 103, 205, 303 102, 206, 303 103, 205, 303 103, 205, 303 103, 205, 303 103, 205, 303 103, 205, 303 HLA-12 HLA-20 HLA-25 HLA-26 HLA-50 HLA-51 HLA-60 HLA-65 HLA-80 HLA-100 HLA-120 HLA-130 HLA-160 HLA-175 HLA-225 a (max.) 0.406 [10.32] 0.563 [14.29] 0.688 [17.46] 0.563 [14.29] 0.688 [17.46] 0.906 [23.02] 0.906 [23.02] 0.906 [23.02] 1.313 [33.34] 0.906 [23.02] 1.313 [33.34] 1.313 [33.34] 1.313 [33.34] 1.313 [33.34] 1.313 [33.34] length 0.062 [1.59] 1.750 [44.45] 2.000 [50.80] 2.000 [50.80] 3.000 [76.20] 4.000 [101.60] 3.500 [88.90] 4.000 [101.60] 4.500 [114.30] 4.000 [101.60] 6.500 [165.10] 6.000 [152.40] 6.500 [165.10] 8.000 [203.20] 8.500 [215.90] 10.500 [266.70] o.d. 0.313 [7.94] 0.438 [11.11] 0.563 [14.29] 0.438 [11.11] 0.563 [14.29] 0.750 [19.05] 0.750 [19.05] 0.750 [19.05] 1.125 [28.58] 0.750 [19.05] 1.125 [28.58] 1.125 [28.58] 1.125 [28.58] 1.125 [28.58] 1.125 [28.58] i.d. 0.031 [0.79] 0.188 [4.76] 0.313 [7.94] 0.313 [7.94] 0.313 [7.94] 0.313 [7.94] 0.500 [12.70] 0.500 [12.70] 0.500 [12.70] 0.750 [19.05] 0.500 [12.70] 0.750 [19.05] 0.750 [19.05] 0.750 [19.05] 0.750 [19.05] 0.750 [19.05] terminal setback 0.31 [0.79] 0.094 [2.38] 0.094 [2.38] 0.094 [2.38] 0.094 [2.38] 0.094 [2.38] 0.125 [2.38] 0.125 [3.18] 0.125 [3.18] 0.219 [5.56] 0.125 [3.18] 0.219 [5.56] 0.219 [5.56] 0.219 [5.56] 0.219 [5.56] 0.219 [5.56] adj. slider 70 71 72 71 72 73 73 73 74 73 74 74 74 74 74 terminal designation optional 14 n 14 n 15 n 14 n 15 n 15 n 15 n 15 n 15 n 15 n 15 n 15 n 15 n 15 n 15 n standard 05z 02z 06z 02z 06z 06z 06z 06z 07z 06z 07z 07z 07z 07z 07z core dimensions distance between terminals (ref) 1.187 1.437 1.312 2.437 3.312 2.75 3.250 3.750 2.812 5.750 4.812 5.312 6.812 7.312 9.312 model dimensions in inches [millimeters]
