Epo Function & Digital Input - Delta M100 210 Operation And Installation Manual

3.7.2 EPO Function & Digital Input
The communication Module has an emergency power off function (EPO).
Users can customize EPO function in APP or Delta Solar System (DSS).
Once enabled, the EPO function can be used to turn off the inverter via a NO
relay contact connected across terminal [VCC & K0].
Additionally, a digital power reduction control is available that can be set to
limit the inverter's available active output power. The control settings for this
function are made by placing a hardware short (jumper or relay) between two
terminals of the terminal block shown in Table 3-5, below.
