4 Installation and Wiring

Route the MECHATROLINK communications cables separately from the main circuit wiring and

other power lines.

4.1 Installing the SI-T Card

Use the following procedure to mount the SI-T Card after removing the Inverter’s Digital

Operator and front cover.

1. Turn OFF the Inverter’s main-circuit power supply.

2. Confirm that all the indicators on the Inverter have turned OFF, wait until the specified

period of time has elapsed (the time is shown on the Inverter’s front cover), and then

remove the Digital Operator and the front cover. Verify that the CHARGE lamp is unlit.

3. Remove the Option Clip (the clip to secure option C or D) on the Inverter. The Clip can

be easily pulled out by pinching its projections.

4. Install the SI-T Card on the option C connector 2CN (60 pins) on the Inverter control

board. Secure the Card by inserting the spacers on the control board into the spacer

mounting holes (three holes) of the Card until hearing a “click.” (Refer to A in Fig.1.)

Note: The SI-T Card (option C) and option D cannot be used at the same

time.

5. Insert the Option Clip to its original position.

6. Connect the Card grounding cable to the control circuit terminal E (G) on the Inverter

control board.

7. After the Card is installed, connect the communications cables and set the DIP switches.

(Refer to 3.4 and 4.2.)

8. Remount the Digital Operator and the front cover.

• Before installing or removing the Option Card, or performing wiring operations, always turn OFF the

power to the Inverter and wait until the specified period of time has elapsed after all the Inverter

indicators have turned OFF. (The time is shown on the Inverter’s front cover.)

Failure to do so can result in electric shock.
