2.1 REMOVING THE DRIVE'S COVER:
Press on the both finger grips on both side corners of the cover until the retaining clips disengage from the drive and lift it up. This cover must
be replaced with the new cover (supplied), as described in Section 5, on page 4.
2.2 REMOVING THE DRIVE'S INTERFACE HEADER COVERS:
Both covers must be removed off of headers CON1 and CON2, on the drive. These covers are no longer needed and may be discarded.
2.3 INSTALLING THE IODF
Align the IODF CON1 and CON2 over the corresponding headers on the drive. The IODF should easily drop down into the headers
approximately 1/8" (3 mm) and the IODF PC board should rest on all three clips. To complete the installation of the IODF, press down firmly
on the PC board near the top two clips and then on the shorter Terminal Block TB2 until the IODF is secured onto the drive with all three clips.
3 ELECTRICAL CONNECTIONS
Wire the control in accordance with the National Electrical
Code requirements and other local codes that may apply
to the application. See Figure 3, for connections to
Terminal Blocks TB1 and TB3. See Table 1 for the
terminal block wire and tightening torque specifications.
WARNING! HIGH VOLTAGE! Read Safety
Warnings, on page 1, before using the drive.
Disconnect the main power before making
connections to the drive or the IODF. To avoid electric
shock, be sure to properly ground the drive.
Application Note:
To avoid erratic operation, do not
bundle AC Line input and motor wires with each other.
Also, do not bundle motor wires from multiple drives in the
same conduit. Use shielded cables on all signal wiring
over 12" (30 cm). The shield should be earth grounded on
the drive side only.

3.1 MULTI-FUNCTION INPUT TERMINALS
MFIT 6 is factory programmed for Up Frequency Command (Function 7.05 set to "0003"). MFIT 7 is factory programmed for Down Frequency
Command (Function 7.06 set to "0004"). When the MFIT 6 contact is closed, the drive's frequency will increase. When the MFIT 7 contact is
closed the drive's frequency will decrease. Also see Section 8.4.2.3, on page 34 of the manual. MFIT 6 and MFIT 7 can be changed from their
factory settings of Up Frequency Command and Down Frequency Command by reprogramming Functions 7.06 and 7.07, as shown in Table
2, on page 3. Also see Tables 3 and 4, on page 3.
Free-Running Operation:
When the Up Contact is closed, the drive output frequency will increase for the duration of the contact closure.
When the Up Contact is opened, the drive output frequency will stop increasing. When the Down Contact is closed, the drive output frequency
will decrease for the duration of the contact closure. When the Down Contact is opened, the drive output frequency will stop decreasing.
