■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.

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.
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.

Vertical mounting

Horizontal mounting
• 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.)

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 °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.

with any standards, codes or regulations which apply to the combination of the
Product in the Buyer’s application or use of the Product. At Buyer’s request,
Omron will provide applicable third party certification documents identifying
ratings and limitations of use which apply to the Product. This information by
itself is not sufficient for a complete determination of the suitability of the Prod-
uct in combination with the end product, machine, system, or other application
or use. Buyer shall be solely responsible for determining appropriateness of
the particular Product with respect to Buyer’s application, product or system.
Buyer shall take application responsibility in all cases but the following is a
non-exhaustive list of applications for which particular attention must be given:
(i) Outdoor use, uses involving potential chemical contamination or electrical
interference, or conditions or uses not described in this document.
(ii) Use in consumer products or any use in significant quantities.
(iii) Energy control systems, combustion systems, railroad systems, aviation
systems, medical equipment, amusement machines, vehicles, safety equip-
ment, and installations subject to separate industry or government regulations.
(iv) Systems, machines and equipment that could present a risk to life or prop-
erty. Please know and observe all prohibitions of use applicable to this Prod-
uct.
NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS
RISK TO LIFE OR PROPERTY OR IN LARGE QUANTITIES WITHOUT
ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TO
ADDRESS THE RISKS, AND THAT THE OMRON’S PRODUCT IS PROP-
ERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE
OVERALL EQUIPMENT OR SYSTEM.
2. Programmable Products. Omron Companies shall not be responsible for the
user’s programming of a programmable Product, or any consequence thereof.
3. Performance Data. Data presented in Omron Company websites, catalogs
and other materials is provided as a guide for the user in determining suitabil-
ity and does not constitute a warranty. It may represent the result of Omron’s
test conditions, and the user must correlate it to actual application require-
ments. Actual performance is subject to the Omron’s Warranty and Limitations
of Liability.
4. Change in Specifications. Product specifications and accessories may be
changed at any time based on improvements and other reasons. It is our prac-
tice to change part numbers when published ratings or features are changed,
or when significant construction changes are made. However, some specifica-
tions of the Product may be changed without any notice. When in doubt, spe-
cial part numbers may be assigned to fix or establish key specifications for
your application. Please consult with your Omron’s representative at any time
to confirm actual specifications of purchased Product.
