(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. slider model number width height hole diameter 70 0.188 [4.76] 0.516 [13.10] 0.125 [3.18] 71 0.250 [6.35] 0.594 [15.08] 0.156 [3.96] 72 0.250 [6.35] 0.719 [18.26] 0.141 [3.58] 73 0.250 [6.35] 0.781 [19.84] 0.141 [3.58] 74 0.313 [7.94] 0.781 [19.84] 0.170 [4.32] hei g ht hole dia. width styles 14 and 15 b d a c b d c a style 02 thru 07 dimension terminal type 02 05 06 07 14 15 a 0.188 0.188 0.250 0.375 0.188 0.250 [4.76] [4.76] [6.35] [9.53] [4.76] [6.35] b 0.406 0.438 0.563 0.625 0.563 0.594 [10.32] [11.118] [14.29] [15.88] [14.29] [15.08] c 0.093 0.104 0.166 0.173 0.050 0.065 [2.36] [2.64] [4.22] [4.39] [1.27] [1.65] d 0.020 0.020 0.020 0.020 0.020 0.031 [0.51] [0.51] [0.51] [0.51] [0.51] [0.79] ambient temperature in c 120 100 8 0 60 40 20 0 % n i r e w o p d e t a r derating 25 - 65 - 50 0 50 150 250 350
