4 ELECTRICAL CONNECTIONS
See Sections 4.1 – 4.11, on pages 15 – 38, for the electrical connections to the IODA.
See Figure 10, below, for Terminal Block TB1 Layout. Common Terminals "8", "12",
"14", "16", "18", "20", and "22" (shown shaded) are all internally connected and can be
used with the Multi-Function Input Terminals "1" – "7", Signal Inputs 1 and 2, and
Signal Outputs 1 and 2.
See Table 1, on page 14, for Terminal Block TB1 Wire and Tightening Torque
Specifications. See Table 2, on page 14, for Terminal Block TB1 Functions, Features
and Terminal Assignments.
WARNING! HIGH VOLTAGE – Read Safety Warning, on page 4, before
using the drive. Disconnect main power before making connections to the IODA
or the drive. To avoid electric shock, be sure to properly ground the drive.
Do not depend on the LEDs or the 4-Digit Display, to no longer be illuminated as
a guaranteed power off condition. Be sure the main power switch or circuit
breaker is in the "OFF" position before servicing the drive.
Application Note: To avoid erratic operation, do not bundle the AC line and
motor wires with each other or with wires from signal following, start/stop
contacts, or any other signal wires. Also, do not bundle motor wires from
multiple drives in the same conduit. Use shielded cables on all signal wires over
12" (30 cm). The shield should be earth grounded on the drive side only.
Connect the drive in accordance with the National Electrical Code requirements
and other local codes that may apply.
Local/Remote Operation: When using the IODA with signal following or remote
start/stop, it is desirable to program the drive for Local/Remote Operation. In this
mode, the drive frequency setting can be toggled between a process signal and the
keypad using the JOG-LCL/REM Key. The following functions can be switched
between "remote" and "local" (Keypad) operation: Start/Stop, Forward/Reverse,
Analog Signal Inputs 1 and 2, and Up/Down Frequency Control.
Set Jog-Local/Remote (Function No. 2.02) to Jog Disabled; Local/Remote Enabled
("0002") to change the JOG-LCL/REM Key from Jog Operation to Local/Remote
Operation.
Note: To stop the drive using the Keypad, when in Remote Operation, first press the
JOG-LCL/REM Key and then the Stop Key.
