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.
To remove or replace the Power Device Cartridge for the G3PA-210B(L)-VD(-X), G3PA-220B(L)-VD(-X), or G3PA-420B-VD(-2), use the special

tool provided with it for extraction. (No special tool is required for other models.)
The G3PA can be broadly divided into two series: Previous models and models with model numbers that end with "-VD." The Cartridge shown at

the right cannot be mounted to models in the G3PA-

@@@

B-(-US) Series.

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

Replacement Procedure

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

To remove or replace the Power Device Cartridge, use the special tool provided with it for extraction.

(Do not switch on the power without the Power Device Cartridge. For details, see the attached the instruction sheet with the product.)

Extraction

Follow the procedures below to dismount the Power Device

Cartridge from the G3PA.

1. Switch off the power.
2.

Remove the terminal cover.

Hook the indented part of the cartridge with the tool and pull up on

the cartridge to remove it.

Mounting

Follow the procedures below to mount the Power Device Cartridge

on the G3PA.

Apply silicone grease (provided with the G32A-A) to the entire

surface of the heat sink.

Make sure that there is no dust or pieces of wire on the heat sink

of the G32A-A or the G3PA.

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.

Attach the terminal cover.

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. No special tool is required to remove the Cartridge.

Extraction

Follow the procedures below to dismount the G32A-A Power Device

Cartridge from the G3PA.

1. Switch off the power.
2.

Remove the terminal cover.

Loosen the two centered screws on the sides to dismount the

cartridge. The screws are connected to terminals 1 and 2.

Loosen the screws on both the corners.

Hold the indented part of both the corners to dismount the

cartridge.

Mounting

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

Make sure that there is no dust or pieces of wire on the heat sink

of the G32A-A or the G3PA.

Remover

Hook here with
Remover.

Apply silicone grease here.

Side B

Loosen

Apply silicone grease here.

G3PA

Insert the cartridge into the opening of the G3PA so that side A

and side B are even.

Tighten the screws on both the corners with a tightening torque of

0.59 to 0.78 N·m.

Tighten the screws on both the sides with a tightening torque of

0.59 to 0.78 N·m.

Attach the terminal cover.

Switch on the power and check the G3PA to be sure it works

properly.

Safety Precautions

■

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.

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

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.

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

•

Screw or DIN track mounting is possible.

•

Vertical mounting should usually be used.

•

Close mounting cannot be used if the SSR is used at a 100% load

current. Leave a gap of at least 10 mm on the left and right of each
Unit.

•

Close mounting can be used under the following conditions:

1. Close mounting can be performed with no more than three SSRs

(For four or more SSRs, leave a gap of at least 10 mm.)

2. Use a load current of 80% or less (90% or less for the

G3PA-210B-VD, G3PA-220B-VD, or G3PA-240B-VD).

3. Leave a gap of at least 80 mm above and below the SSR.
4. Leave a gap of at least 60 mm from wiring ducts to the top of the

SSR and at least 30 mm from wiring ducts to the bottom of the SSR.

•

With vertical mounting, reduce the load current by 30%.
(Refer to the

Load Current vs. Ambient Temperature

graph.)

Note:

Leave a distance of 60 mm min. between SSRs and ducts (especially above the SSR).

Relationship between SSRs and Ducts

Ventilation

If the air inlet or air outlet has a filter, clean the filter regularly to
prevent it from clogging and ensure an efficient flow of air.

Do not locate any objects around the air inlet or air outlet, otherwise
the objects may obstruct the proper ventilation of the control panel.

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

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

, Air volume: 0.7 m

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

Use short ducts.

Do not surround the SSR
