PG Interface (5 V Line Driver) Card "OPC-G1-PG2"

Thank you for purchasing this PG interface card or 5 V line driver card (hereinafter called PG interface card), "OPC-G1-PG2." Installing
this card to your FRENIC-MEGA enables vector control with speed sensor.

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-PG2" is printed on the PG

interface card. (See 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.

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

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 interface card to the ports othe
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.

Tab

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.

3. Wiring

In general, the covers of the control signal wires are not specifically designed to withstand a high voltage (i.e., reinforced insulation is
not applied). Therefore, if a control signal wire comes into direct contact with a live conductor of the main circuit, the insulation of the
cover might break down, which would expose the signal wire to a high voltage of the main circuit. Make sure that the control signal
wires will not come into contact with live conductors of the main circuit.

Failure to observe these precautions could cause electric shock or an accident.

Noise may be emitted from the inverter, motor and wires.
Take appropriate measures to prevent the nearby sensors and devices from malfunctioning due to such noise.

An accident could occur.

Perform wiring properly, referring to the "Terminal Allocation and Symbol Diagram," "Terminal Specifications," and "Internal Block
Diagram" shown below.

To prevent malfunctioning due to noise, separate the wires for the interface card as far apart as possible from those for the main
circuits. Also, inside the inverter, bundle and fix the wires for the interface card so that they do not come into direct contact with
live parts of the main circuits (for example, the main circuit terminal block).

Connect the shielded layer of the
cable to terminal [CM].
When using an external power
supply, also connect its grounding
wire and shielded cable to this
terminal and tighten them together.
