Operation
■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.
Appearance
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.

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.

• Screw or DIN track
mounting is possible.
• Vertical mounting should
usually be used.
• Close mounting is also
possible.
• Close mounting is possible for
up to 3 G3PA SSRs. (If there
are 4 or more SSRs, mount at
intervals of 10 mm min.)

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

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 °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 mm2, Air volume: 0.7 m3/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.

If the ducts cannot be

Use short ducts.
Do not surround the SSR
