Power connectors
- mating connector: M6 cable lug 10 - 50 mm2 + M6 screw. Terminal thread length is 13 mm, maximum tightening torque is 10 Nm.
Mounting screws
- 4x M4 or M5 screw. M4 screws are through the heatsink, M5 screws have a thread in the heatsink. Refer to the SX controller drawing.
- for through-hole mounting, minimum thread depth is 1.5 x screw diameter. Tightening torque depends on the material of the mounting base.
Thermal grease
- to improve cooling of the controller, you should apply thermal grease to the mounting area of the controller. Example: Electrolube HTC, AG termopasty HPX
