Determine the wire size for the main circuit so that line voltage drop is within 2% of the rated voltage. Line
voltage drop is calculated as follows:
x wire resistance (Ω/km) x wire length (m) x current (A) x 10

removing any cover. The charge lamp located within the Drive should be off prior to working inside. Even if
the charge lamp is off, one must measure the AC input, output, and DC Bus potential to insure safe levels
prior to resuming work. Failure to adhere to this warning may result in personal injury or death.

Electrical Installation 2 - 10
Cable Length between Drive and Motor
The E7 should be installed as close as possible to the motor to minimize the length of load side power cable needed between
the Drive and the motor.
If the cable between the Drive and the motor is long, the high-frequency leakage current will increase, causing the Drive
output current to increase as well. This may affect peripheral devices. To prevent this, reduce the cable length whenever
possible, or if necessary, adjust the carrier frequency (set in C6-02) as shown in Table 2.6.
The line side power cables, load side power cables and the control wiring should all be run in a separate conduit. Careful attention to this recommended design practice will avoid many potential motor and Drive related problems.
Table 2.6 Motor Cable Length vs. Carrier Frequency (C6-02)
Motor Cable Length 164 ft. (50m) maximum 328 ft. (100m) maximum More than 328 ft.(100m)
Carrier Frequency 15kHz maximum 10kHz maximum 5kHz maximum
(See the limitations on carrier frequency, based on Drive capacity and model number in Appendix B).
Ground Wiring
Observe the following precautions when connecting the ground wire:
1. 208-240Vac Drives should have a ground connection with resistance of less than 100Ω.
2. 480Vac Drives should have a ground connection with resistance of less than 10Ω.
3. Do not share the ground wire with other devices, such as motors or large-current electrical equipment.
4. Always use a ground wire that complies with technical standards on electrical equipment and minimize the length of the
ground wire. Leakage current flows through the Drive. Therefore, if the distance between the ground rod and the ground
terminal is too long, potential on the ground terminal of the Drive will become unstable.
5. When using more than one Drive, be careful not to loop the ground wire. See Fig 2.4.

Control Circuit Ground Terminals
The removable Drive control terminal card provides two ground terminals (marked TB3 and TB4) to accept the control wire
shield connection. The control wire shield should be connected on this end only, the opposite end should be isolated with
electrical tape.
IMPORTANT
Grounding of the E7 enclosure and motor is required for proper system operation.
Electrical Installation 2 - 11
Control Wiring
Control Circuit Wire Sizes
The auto mode speed reference (speed command) field wiring connection is made to E7 Drive terminals A1 or A2 (signal
positive), AC (signal common) and G (shield). Keep this lead length as short as possible to maintain signal quality. Insulated
twisted shielded pair wire (2 conductor # 18 ga, Belden 8760 or equivalent) is required. Do not run these wires in the same
conduit as other AC power or control wires. The shield must be connected on this end only, stub and isolate the other end. The
A2 signal employed is 4 to 20 mA with parameter H3-08 set for “2: 4 - 20 mA”. For 0 to 10 VDC, parameter H3-08 is set for
“0: 0 - 10 VDC” and the E7 control board DIP switch S1-2 must be in the OFF position. (See Fig 2.4).
For remote operation, keep the length of the control wiring to 50m or less. Separate the control wiring from high-power lines
(input power, motor leads or relay sequence circuits) to reduce noise induction from peripheral devices.
When setting speed commands (frequency references) from an external speed potentiometer (and not from the Digital Opera-
tor), use shielded twisted-pair wires and ground the shield to terminal E(G), as shown in Fig 2.3. Terminal numbers and wire
sizes are shown in Table 2.7.

Control Circuit Wiring Precautions
Observe the following precautions when wiring control circuits:
1. Separate control wiring from power/motor wiring (terminals R/L1, S/L2, T/L3, U/T1, V/T2, W/T3, , 1, 2, and
3) and other high-power lines.
2. Separate wiring for control circuit terminals MA, MB, MC, M1, M2, M3, and M4 (digital outputs) from wiring to other
control circuit terminals.
3. If using an optional external power supply, ensure it is a UL Listed Class 2 power supply source.
4. Use twisted-pair or shielded twisted-pair cables for control circuits to prevent operating faults. Prepare cable ends as
shown in Fig 2.7.
5. Connect the shield wire to terminal E(G).
6. Insulate the shield with tape to prevent contact with other signal lines and equipment.
