Page 5: Operation
G3PA 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. - Page 6 G3PA ■ Replacement Procedure G32A-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.

Page 14: Close Mounting
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. The rated load current of an SSR is measured at an ambient Panel Mounting (At a rated ambient temperature of 40°C). - Page 15 (a) Exclusive Warranty.
