Preface Thank you for purchasing our analog output interface card. This instruction manual describes the analog output interface card "OPC-AO" designed for the inverter series of inverters. Mounting the analog output interface card on your inverter enables analog input (voltage and current for each terminal) and analog output (voltage and current for each terminal) to/from the inverter.
Installation and wiring • Before changing the switches, turn OFF the power and wait at least 10 minutes. Make sure that the charging lamp is turned OFF. Further, make sure, using a multimeter or a similar instrument, that the DC link bus voltage between the terminals P(+) and N(-) has dropped to the safe level (+25 VDC or below).

Disposal • Treat the interface card as an industrial waste when disposing of it. Otherwise injuries could occur. Others • Never modify the interface card. Doing so could cause an electric shock or injuries. ...

(2) The interface card is not damaged during transportation--no defective parts, dents or warps. (3) The model name "OPC-AO" is printed on the interface card. (See Figure 1.1.) If you suspect the product is not working properly or if you have any questions about your product, contact the shop where you bought the product or your local Fuji branch office.
1.3 Installation and Removal of the Interface Card Before changing the switches, turn OFF the power and wait at least 10 minutes. Make sure that the charging lamp is turned OFF. Further, make sure, using a multimeter or a similar instrument, that the DC link bus voltage between the terminals P(+) and N(-) has dropped to the safe level (+25 VDC or below).
Fit the positioning cutout of the card over the tab on the inverter to determine the mounting position. Insert connector CN1 on the interface card into the option connection ports on the inverter's control PCB. Note: Be sure to follow the order of Inserting first lead...
1.4 Wiring Before changing the switches, turn OFF the power and wait at least 10 minutes. Make sure that the charging • lamp is turned OFF. Further, make sure, using a multimeter or a similar instrument, that the DC link bus voltage between the terminals P(+) and N(-) has dropped to the safe level (+25 VDC or below). • Qualified electricians should carry out wiring. Otherwise, an electric shock could occur.

Depending upon the wire type and the number of wires used, the front cover may be lifted by the wires, which impedes normal keypad operation. If it happens, change the wire type or size. Route the wires, taking care not to let them go over the control PCB, as shown in Figure 1.4. Otherwise, malfunctions may occur.
