Figure 2.3 Changing the Positions of the Top and Bottom Mounting Bases When changing the positions of the top and bottom mounting bases, use only the specified screws. Otherwise, a fire or accident could occur. (3) Mounting notes The EQ7-2007-C / EQ7-4007-C through EQ7-2040-C / EQ7-4040-C should be mounted with four screws or bolts using screw holes A or B shown below. Note that, at each of the top and bottom of the inverter, the two screws or bolts should be located in a bilaterally symmetrical position. 2-3
2.3 Wiring Follow the procedure below. (In the following description, the inverter has already been installed.) 2.3.1 Removing and mounting the front cover and the wiring guide (1) For inverters of 40 HP or below First loosen the front cover fixing screw, slide the cover downward holding both sides, tilt it forward, and then pull it upward, as shown below. While pressing the wiring guide upward, pull it out and forward. After carrying out wiring (see Sections 2.3.2 through 2.3.6), put the wiring guide and the front cover back into place in the reverse order of removal. Figure 2.4 Removing the Front Cover and the Wiring Guide (e.g EQ7-4020-C) (2) For inverters of 50 to 1000 HP Loosen the four front cover fixing screws, hold the cover with both hands, slide it upward slightly, and pull it forward, as shown below. After carrying out wiring (see Sections 2.3.2 through 2.3.6), align the screw holes provided in the front cover with the screws on the inverter case, and then put the front cover back into place in the reverse order of removal. To expose the control printed circuit board (control PCB), open the keypad enclosure. Figure 2.5 Removing the Front Cover (e.g. EQ7-4050-C) Tightening torque: 15.9 lb-in (1.8 Nm) (M4) 31.0 lb-in (3.5 Nm) (M5) 2-4
