Electrical Connection
Warning: please cut off the main power supply before remove the independent terminal cover.
(1)Loosen four bolts from the electric warehouse, take off the junction box. See picture 3-2
(2)Screwing cable sealing joint and through the cable. Caution: power cable: Main circuit wirings should be using metallic sealed pipe joint. Control cables: must be using shielded cables with metallic sealed pipe joint to prevent electromagnetic interference. Filed bus cable: the shield can be earthed on the circuit board of bus interface .
(3) Take XI terminal off the control board. If it with relay board, take X2 terminal off relay board and X3 terminal off driver board. Using screwdriver to push/pull out the terminal from the plug board, if need be.
(4)According to the connection diagram (pic 3-4), connect the power supply and control line. Make sure the protective earth (PE) connected with the ground point in internal actuator.
(5)Install terminal XI on the control board, terminal X2 on the replay board, terminal X3 on the driver board.
(6)Put the junction box back on the electronic storehouse, cable service entrance should be installed horizontal downward at the moment.
(7)Screw the cable seal pipe joint Important: during installation, the most important of all is make sure the sealed tube cable joint and sealed ring (Otype ring) have been assembled well so as to meet the required protection level. For details of allowed diameter of conductor, refer to wiring diagram.
