The time it takes for the DC network to discharge is shorter if you break on the DC side than on the AC side, so it is our recommendation to place the fireman switch on the DC cabling.<\/p><p>On the DC side, the fireman switch will be placed as close to the EnergyHub as possible, thus placing it between the EnergyHub and the rest of the DC grid.<\/p><p>With a fireman switch installed on the AC side, the AC supply to the EnergyHub will be de-energized, the EnergyHub will shut down and then discharge the DC grid.<\/p><p>Similar to a normal shutdown via the switch, in this case it will take about 10-15 minutes before the EnergyHub has discharged its cone banks and the DC grid becomes de-energized.<\/p><p>With a DC fireman switch, the firefighter switch cuts the supply between the EnergyHub and the DC distribution box. This causes the DC grid to become de-energized, which contributes to SSOs and ESOs shutting down.<\/p><p>For powershare installations, we recommend placing \u00a0fireman r switches on each connection to the power grid, as it is not enough to break at an EnergyHub for the DC grid to be de-energized.<\/p><p>The fireman switches developed by Ferroamp have an IP65 rating and can be placed
