Installation and Wiring
Before using the DI-16H2, be sure to read this instruction manual and the instruction manual for the
Inverter connected to the DI-16H2.
4.1
Installing the DI-16H2 on the Inverter
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 Inverter’s front cover. Verify that the CHARGE lamp is unlit.
3. Install the DI-16H2 on the connector 2CN (60 pins) on the Inverter control board.
Secure the DI-16H2 by inserting the spacers on the control board into the spacer mount-
ing holes (two holes) of the DI-16H2 until hearing a “click.” (Refer to A in Fig.1.)
4. For VS-616H3, VS-676VG3/VH3, and VS616G5 series Inverters, connect the FG cable
of DI-16H2 to the ground connecting terminal (12).
For Varispeed G7/F7 and Varispeed AC series Inverters, connect the FG cable of DI-
16H2 to the Inverter’s control terminal E (G).
5. After the DI-16H2 is installed, connect to the peripheral devices.
6. Remount the Inverter’s 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.
