## ■ **Replacement Parts** 

## **G32A-A Power Device Cartridge** 

The G32A-A Power Device Cartridge (a Triac Unit) can be replaced with a new one. When the temperature indicator has changed from pink to red, the triac circuitry may have malfunctioned possibly by an excessive flow of current, in which case, dismount the damaged cartridge for replacement. 

The damaged cartridge can be replaced with a new one without disconnecting the wires from the G3PA. 

Improve the heat radiation efficiency of the G3PA before replacing the cartridge. 

The G32A-A Power Device Cartridge can withstand an excessive current for a short period of time, such as may be caused accidentally by the short circuitry of the load, in which case the temperature indicator will not turn red. 

Be sure to turn OFF the power supply when replacing the Cartridge. Supplying power with the Cartridge removed may result in malfunction.

## **Replacing Power Device Cartridges** 

When replacing Power Device Cartridges, use the specified model. Using a Power Device Cartridge other than the specified one will result in faulty operation and destruction of the elements.

## ■ **Replacement Procedure** 

## **G32A-A10(L)-VD/G32A-A20(L)-VD/G32-A420-VD(-2)** 

Use the special tool (provided) to extract the cartridge for replacement with a new one. 

## **Extraction** 

Follow the procedures below to dismount the Power Device Cartridge from the G3PA. 

**1. Switch off the power.** 

**2.** Remove the terminal cover. 

**3.** Hook the indented part of the cartridge with the tool and pull up on the cartridge to remove it.

**2.** Make sure that there is no dust or pieces of wire on the heat sink of the G32A-A or the G3PA. 

**3.** Insert the cartridge into the opening of the G3PA so that the letters on the cartridge and those on the G3PA are in the same direction and side A and side B are even.

## **Mounting** 

Follow the procedures below to mount the Power Device Cartridge on the G3PA. 

**1.** Apply silicone grease (provided with the G32A-A) to the entire surface of the heat sink. 

**4.** Attach the terminal cover. 

**5.** Switch on the power and check the G3PA to be sure it works properly. 

## **G32A-A40(L)-VD/G32A-A60(L)-VD/G32A-A430-VD(-2)/G32A-A450-VD-2** 

The G32A Power Device Cartridge is mounted and secured with screws to the G3PA Unit. 

## **Extraction** 

Follow the procedures below to dismount the G32A-A Power Device Cartridge from the G3PA. 

## **Mounting** 

   **1.** Apply silicone grease to the entire surface of the heat sink. 

**1. Switch off the power.** 

**2.** Remove the terminal cover. 

**3.** Loosen the two centered screws on the sides to dismount the cartridge. The screws are connected to terminals 1 and 2.

**3.** Insert the cartridge into the opening of the G3PA so that side A and side B are even. 

**4.** Tighten the screws on both the corners with a tightening torque of 0.59 to 0.78 N·m. 

**5.** Tighten the screws on both the sides with a tightening torque of 0.59 to 0.78 N·m.

## **Safet Precautions y** 

## ■ **Precautions for Correct Use** 

Please observe the following precautions to prevent failure to operate, malfunction, or undesirable effect on product performance. 

## **Load Connection** 

For an AC load, use a power supply rated at 50 or 60 Hz. The maximum operating frequency is 10 Hz. The G3PA-(VD) has a built-in varistor for overvoltage protection. 

At a low applied voltage, such as 24 VAC, the load current is not fully supplied. When the Unit is switched ON, the voltage required to power the Unit deprives the output signal of the necessary voltage level and thus creates loss time. The lower the load voltage is, the greater the loss time is. This condition, however, will not create any serious problems. 

Load so ~~L,~~ Load power Input SSR supply 

When attaching a heat sink to the G3PA-(VD), in order to facilitate heat dissipation, apply silicone grease or equivalent heat-conductive grease on the heat sink. (Toshiba Silicone, Shinetsu Silicone, etc.) 

Tighten the mounting screws of the heat sink with a torque of 0.78 to 0.98 N·m. 

## **Noise Terminal Voltage according to EN55011** 

The G3PA-(VD) complies with EN55011 standards when a capacitor is connected to the load power supply as shown in the following circuit diagram.

Loss time<br>**----- End of picture text -----**<br>


Recommended Capacitor: 1 µF, 250 VAC 

For a DC or L load, a diode should be connected in parallel the load to absorb the counter electromotive force of the load.

A heat exchanger, if used, should be located in front of the SSR Units to ensure the efficiency of the heat exchanger. 

## **Please reduce the ambient temperature of SSRs.** 

## **The rated load current of an SSR is measured at an ambient temperature of 25 or 40** ° **C.** 

An SSR uses a semiconductor in the output element. This causes the temperature inside the control panel to increase due to heating resulting from the passage of electrical current through the load. To restrict heating, attach a fan to the ventilation outlet or air inlet of the control panel to ventilate the panel. This will reduce the ambient temperature of the SSRs and thus increase reliability. (Generally, each 10 °C reduction in temperature will double the expected life.)

Example: For 10 SSRs with load currents of 20 A, 0.31 x 10 = 3.1 Thus, 4 fans would be required. Size of fans: 92 mm[2] , Air volume: 0.7 m[3] /min, Ambient temperature of control panel: 30 °C 

**If there are other instruments that generate heat in the control panel other than SSRs, additional ventilation will be required.**
