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.

Load Connection Load power supply SSR Input 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.) 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. Tighten the mounting screws of the heat sink with a torque of 0.78 to 0.98 N·m. 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. 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. Load Input G3PA-(VD) Output Loss time 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. Mounting Vertical • Screw or DIN track mounting is possible. • Vertical mounting should usually be used. Vertical mounting Vertical Panel DIN track G3PA Vertical The rated ambient temperature is 40°C. (30°C for 400 V.) G3PA 80 mm DIN track Close mounting • 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.) Horizontal mounting Panel Note: Leave a distance of 60 mm min. between SSRs and ducts (especially above the SSR). 14 G3PA Close Mounting A heat exchanger, if used, should be located in front of the SSR Units to ensure the efficiency of the heat exchanger. SSR Mounting Pitch Please reduce the ambient temperature of SSRs. Panel Mounting (At a rated ambient temperature of 40°C). The rated load current of an SSR is measured at an ambient temperature of 25 or 40 °C. Duct or airflow obstruction SSR 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.) 60 mm min.

G3PA G3PA Mounting surface G3PA Mounting surface Mounting surface Duct or airflow obstruction Airflow Duct or airflow obstruction Do not surround the SSR with ducts, otherwise the heat radiation of the SSR will be adversely affected. Use short ducts. If the ducts cannot be shortened, place the SSR on a metal base so that it is not surrounded by the ducts. Ventilation Be aware of air flow Duct or air flow obstruction Ventilation outlet G3PA G3PA G3PA Air inlet 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.
