2. Mounting and Wiring
2.1 Mounting Notes
Mounting the EQ7 in a control cabinet
1) Remove all base fixing screws and case fixing screws from the top of the inverter.
2) Move the top mounting base to the center of the inverter and secure it to the case fixing screw
holes with the base fixing screws. (After changing the position of the top mounting base, some
screws may be left unused.)
3) Remove all base fixing screws from the bottom of the inverter, move the bottom mounting base to
the center of the inverter, and secure it with the base fixing screws, just as in step 2). (Inverters of
450 HP or below have no case fixing screws on the bottom.)
Figure 2.1: 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.
(4) Mounting notes
Refer to the EQ7 Instruction Manual Chapter 2 for detailed
mounting Information.
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.

2.2 Wiring
Follow the procedure below. (In the following description, the inverter has already been installed.)
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 Section 2.3 of the EQ7 Instruction Manual), put the wiring guide
and the front cover back into place in the reverse order of removal.
Figure 2.2: 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 Section 2.3 of the EQ7 Instruction Manual), 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.
Tightening torque: 15.9 lb-in (1.8 Nm) (M4)
31.0 lb-in (3.5 Nm) (M5)

3. Input Power and Motor Connection
Checking prior to applying power
Fig.3.1 below shows the electrical connections for the input power and motor terminals for various
EQ7 DRIVE models. Verify the input power and motor terminals of the model you are installing.WITH
POWER OFF, make the appropriate connections.
Make sure to follow good wiring practices and all applicable codes. Ensure
that the equipment is grounded properly as shown.
DANGER, LETHAL VOLTAGES ARE PRESENT- Before applying power to the
EQ7 drive, ensure that the terminal cover is fastened and all wiring
connections are secure. After the power has been turned OFF, wait at least ten
minutes until the charge indicator extinguishes completely before touching
any wiring, circuit boards or components.

*1. Refer to page 12 & 13 for connecting a DC reactor from the terminals P1 and P(+).
*2. Make sure the drive is properly sized for single phase input (consult factory).
(Refer to Table 2.6 Recommended Wire Sizes in the EQ7 Instruction Manual).

Never connect power supply wires to the EQ7 drive output terminals U, V, and W. Doing so and turning
the power ON damages the inverter.
Be sure to connect the grounding wires of the EQ7 drive and the motor to the ground electrodes.
Otherwise, an electric shock could occur.
Check the following before powering on the EQ7 drive.
1) Check that the wiring is correct. In particular check the wiring to the EQ7 drive input terminals
L1/R, L2/S and L3/T and output terminals U, V, and W. Also check that the grounding wires are
connected to the grounding terminals ( G) correctly. See Figure 3.1.
2) Check the control circuit terminals and main circuit terminals for short circuits or ground faults.
3) Check for loose terminals, connectors and screws.
4) Check that the motor is separated from mechanical equipment.
5) Make sure that all switches of devices connected to the inverter are turned OFF. Powering on
the inverter with any of those switches being ON may cause an unexpected motor operation.
6) Check that safety measures are taken against runaway of the equipment. Also ensure that all
safety guards are in place to prevent human injury.

4. LED Monitor, LCD Monitor and Keys
The keypad allows you to start and stop the motor, view various data including maintenance
information and alarm information, configure function codes, monitor I/O signal status, copy data, and
calculate the load factor.
