Page 8: Operation
Both ground fault pickup level and time delay are adjusted using the bank of Dipswitches located on the front plate of the GFR-RM relay, which is located inside the Gemini enclosure. (Refer to I-Gard Manual IM-GFR-RM) for complete details of this relay). -
Page 9: Maintenance
Gemini is designed and constructed to operate properly with minimal maintenance, however, it is recommended that it be tested on a regular basis at a minimum of once every six months. The self-test feature allows for a rapid and reliable test. Gemini Instruction Manual I-GARD... - Page 10 The exterior may be cleaned using a slightly damp cloth. Ensure that the Gemini is completely dry before energizing. Close the front door and reconnect electrical power. Test the unit again before returning to normal service.
