Connecting Power cable of GSD to Inverter Circuit breaker or independent Circuit breaker
GSD is powered by same circuit breaker where Inverter AC is connected. This acts as reference
and source for the triggering signal for DRMO.
The TMAC GSD POWER CABLE supplies mains power to the TMAC GSD. The POWER CABLE
is connected to the Main Switch Inverter Supply (MSIS) within the switchboard.
Please note, the wiring is done as per AS/NZS 3000:2018, and that GSD is fitted inside
MSB/Switchboard or Inside the SOFAR Sub boards.
Inspections by Energy Queensland
• Inspections will be carried out by Ergon / Energex field staff
• These will check for the presence, and correct installation of the GSD
• Non-compliance issues will be addressed directly with the premise occupant
• It is in all parties’ best interest to ensure correct installation to avoid having to return to site or
manage customer complaints.
