THE INSTALLATION OF THE CONTROLLER

1. Installation tools

 

(1) Electric drill, drill bit (specification: φ4.3, (φ5.2, φ6.8), tap (specification: M5,M6,M8).Cross and slotted screwdriver, hexagon wrench (specification: 6#.8#), adjustable wrench (specification: 22"), Needle nose pliers.etc

(2) The installation of the controller bracket requires a φ 5.2 drill and M6 tap

(3) The installation ofthe photoelectric support base requires a φ 6.8 drill bit and an M8 tap

(4) The fixing hole of the crimping buckle of the transmission line needs a φ 4.3 drill bit and an M5 tap

 

2. Installation of built-in controller

 Connect the controller directly to the 35mm electrical rail. lnstalled in the electrical cabinet of the machine.
