■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-VD, G3PA-220B-VD, 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. 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.

■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.

(30°C for 400 V.) Vertical mounting Close 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.) 80 mm Note: Leave a distance of 60 mm min. between SSRs and ducts (especially above the SSR). Vertical VerticalVertical

Panel Mounting (At a rated ambient temperature of 40°C). 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 mm 2, 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.

At the customer's request, OMRON will provide applicable third party certification documents identifying ratings and limitations of use that apply to the products. This information by itself is not sufficient for a complete determination of the suitability of the products in combination with the end product, machine, system, or other application or use. The following are some examples of applications for which particular attention must be given. This is not intended to be an exhaustive list of all possible uses of the products, nor is it intended to imply that the uses listed may be suitable for the products:
