SKU 0741
AS/NZ5033:2021 Clause 5.7
&
AS/NZ4777.1 2024 Clause 6.2
Shutdown Procedure
Placed adjacent to and visible from the equipment to be operated. i.e. “INVERTER”.
Where the inverter is adjacent to the switchboard it is directly connected to, the shutdown procedure may be placed in the switchboard.
Where the building has a fire panel, an additional sign shall be placed at the fire panel with instructions as to the location of the IES Emergency shutdown procedure (Refer label below).

&
AS/NZ4777.1 2024 Clause 6.2
Warning PV Array DC Isolators Do not De-Energize the PV array
Located under the Shutdown procedure. Where the energy source is not de-energised when the IES is shutdown. A warning shall be included in the emergency shutdown indicating that isolation of the energy source, by shutting down the inverter and isolating the IES , may not de-energise the energy source and further action may be required.
