The following procedure is a supplement to other documentation supplied with this equipment and will guide the user in properly wiring the E7 and motor.
It will also show the user how to configure the E7 for Hand and Auto operation.
Danger:
Improper wiring can and will
cause bodily harm as well as damage to the equipment.
Step
1
E7 Model Identification and
Mounting
To make sure you received the correct model, it is essential to verify the E7 nameplate with your order and make sure that the E7 has the correct rating so it can be used with your motor. Please check the nameplate information as shown in the example below.

Check that the available power meets the input power requirements.
Ensure that the output power from the VFD is compatible with the motor requirements.
In the case of systems with multiple VFDs follow the above procedure for each VFD and the motor it will control.
When installing the system, be sure to follow good wiring practices and all applicable codes.
Ensure that the mounting of the various components are secure and that the environment, such as extreme dampness, poor ventilation etc. will not cause system degradation.
Mounting the E7
The mounting of the E7 is extremely important regarding environment and accessibility. Depending on your system, there are various models available and the mounting dimensions (footprint) may be different. Because the mounting procedure is fairly extensive, it is beyond the scope of this document, the user is referred to the E7 User Manual
(Document No. TM.E7.01) received with the E7, Section 1
Physical Installation. Match the model that you received and follow the procedure described in the manual to ensure a safe and functional installation. In cases where the system has more than one E7, refer to the proper clearances required for adequate ventilation. Please pay particular
attention to:
The clearances to be maintained around the enclosure for adequate ventilation.
The environmental specifications such as avoiding excessive dampness, extreme temperatures, chemical exposure, corrosive areas etc. to avoid damage to the equipment and to maintain safety.
Removing and Attaching the Terminal Cover
Improper removal of the E7 terminal cover as well as front cover can cause extensive damage to the E7. To avoid damage to these items, please pay particular attention to the
E7 User Manual, Document No. TM.E7.01, Section 1.7,
Removing and Attaching the Terminal Cover.
Please read this cheat sheet and the E7 User
Manual (TM.E7.01) provided with the E7 thoroughly before attempting any installation.

E7 Motor and
Line Power
Fig.1 & 2 below show the electrical connections for the input power and motor terminals for various E7 models.
Select the proper diagram for the model you are installing
(see Step 1). 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 E7, ensure that the terminal cover is fastened and all wiring connections are
secure. After the power has been turned OFF, wait at least five minutes until the charge indicator extinguishes completely before touching any wiring, circuit boards or components.

!
DANGER
After the power has been turned OFF, wait at least five minutes until the charge indicator extinguishes completely before touching any wiring, circuit boards or components.
Digital Operator turned off.
Using Safety precaution, and referring to Fig.1 or 2, swap any two of the three output leads to the motor (U/T1, V/T2 and W/T3). After the wiring change, repeat
Step 3 to recheck motor direction.
Hand Frequency Reference Selection: b1-12
0: Use digital operator to enter Speed command (factory default)
