Once enabled, the EPO function can be used to turn off the inverter through the
relayless contacts connected to terminals [V1 & K0].
A digital power reduction control function is provided, which can be set to limit the
available active output power of the inverter. The control settings for this function
are made by placing a hardware short circuit (jumper or relay) between the two
terminals of the terminal block shown in Table 3-5.
For Australia and Newzealand, please refer to Table 3-6.
