Fuji Electric OPC-G1-PG Manuals

- 1 - Instruction Manual PG Interface Card "OPC-G1-PG" Thank you for purchasing this PG interface card "OPC-G1-PG." Installing this card to your FRENIC-MEGA enables speed control with speed sensor and pulse train input.
Installing this card disables pulse train inputs to the inverter's terminal [X7].
The FRENIC-MEGA has three option connection ports--A-, B-, and C-ports. Connect this PG interface card to the C-port. Do not connect it to any other port. 1. Check that: (1) A PG interface card and two screws (M3 × 8) are contained in the package. (2) The PG interface card is not damaged during transportation--no defective devices, dents or warps. (3) The model name "OPC-G1-PG/SY" is printed on the back of the PG interface card as shown in Figure 2. (The "PG/SY" on the front is a short name, as shown in Figure 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. Figure 1 Front of Card Figure 2 Back of Card 2. Installation Before starting installation and wiring, turn OFF the power and wait at least five minutes for inverters with a capacity of 22 kW or below, or at least ten minutes for inverters with a capacity of 30 kW or above. Make sure that the LED monitor and charging lamp are 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). Otherwise, electric shock could occur. (1) Remove the front cover from the inverter and expose the control printed circuit board (control PCB). As shown in Figure 3, the PG interface card can be connected to the C-port (CN6) only.  To remove the front cover, refer to the FRENIC-MEGA Instruction Manual, Section 2.3. For inverters with a capacity of 30 kW or above, open also the keypad enclosure. (2) Insert connector CN1 on the back of the PG interface card (Figure 2) into the C-port (CN6) on the inverter's control PCB. Then tighten the two screws that come with the card. (Figure 4) Check that the positioning cutout (Figure 1) is fitted on the tab ( in Figure 4) and connector CN1 is fully inserted ( in Figure 4). Figure 5 shows the PG interface card correctly mounted. Do not connect the PG interface card to the ports other than C-port. Doing so may damage the card. (3) Perform wiring on the PG interface card.  Refer to Section 3 "Wiring." (4) Put the front cover back into place.  To put back the front cover, refer to the FRENIC-MEGA Instruction Manual, Section 2.3. For inverters with a capacity of 30 kW or above, close also the keypad enclosure.  Fit the positioning cutout of the card over the tab on the inverter to determine the mounting position.  Insert connector CN1 on the card into the C-port (CN6) on the inverter's control PCB.
