Apply the correct torque when tightening fasteners in the locations that are listed in table 48. Too low or too high torque when fastening an electrical connection results in a bad electrical connection. To ensure correct torque, use a torque wrench. 156 | Danfoss A/S © 2020.01 AQ275556502253en-000101 / 130R0706...
