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-

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.

2. Installation

Do not connect it to any other port.

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 (
Figure 4). Figure 5 shows the PG interface card correctly mounted.

(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.

3. Wiring

as far apart as possible from those for the

so that they do not come into direct

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 this precaution 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 PG interface card
main circuits. Also, inside the inverter, bundle and fix the wires for the PG interface card
contact with live parts of the main circuits (for example, the main circuit terminal block).

When grounding the shielded
cable, use a crimp ring terminal,
R1.25-3 or the like and fasten it
together with the card using this
screw.
