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/V7 Unit

Use the following procedure to mount the SI-T/V7 Unit after removing the Inverter’s Digital

Operator and front cover.

Be sure to complete the wiring to the Inverter before installing the SI-T/V7 Unit, because the

terminals of the Inverter are hidden from view after the Unit is installed.

1. Turn OFF the Inverter’s main-circuit power supply and wait one minute.

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.

3. Use nippers to cut off the cover of the Inverter’s CN2 connector in the three places-

marked as A in Fig. 1. Be careful that the covers do not fall into the Inverter Unit. If

pieces do fall in, be sure to remove them.

4. Align the mounting fixture with the C tab, and use M3 × 8 SW screws to secure the fix-

ture B.

5. Before installing the SI-T/V7 Unit on the Inverter, connect the grounding cable to the

grounding terminal as shown in Fig. 2 . Three types of grounding cables for various

Inverter capacities are provided. Connect the appropriate cable with a crimp terminal.

6. When installing the SI-T/V7 Unit onto the Inverter Unit, make sure that it is straight.

Align the modular plug (CN10) of the SI-T/V7 Unit with the modular plug (CN1) of the

Inverter, and connector (CN2) with the connector for the SI-T/V7 Unit (CN2).

7. Tighten the screw at position D to affix the SI-T/V7 Unit to the Inverter Unit. The screw

is already screwed in on the Inverter Unit.

8. Return the Digital Operator and the front cover to their original positions.

• Before installing or performing wiring, 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 observe this warning may result in electric shock.
