switch or a potential free relay contact. By closing this external switch or
contact, a user programmable ‘action’ will be performed. Such an action
could for example be to release the AC transfer switch, temporarily
disable the AC input Power Boost feature or force the ePRO Combi to
switch to inverter mode. All this can be congured in ePRO Dashboard.
The EPC 1600 to 1800 models are equipped with one trigger input, while
the EPC 2000 to 3500 models are equipped with two trigger inputs.
4.5 Load Requirements in Inverter Mode
Before you connect your appliance(s) to the ePRO Combi AC output,
always check it’s maximum power consumption. Do not connect
appliances to the AC output requiring more than the nominal power
rating of the inverter continuously. Unless these appliances are switched
on only when the AC transfer switch is activated, and power is drawn
from an external source with a larger capacity than the inverter.
Some appliances like motors or pumps, draw large inrush currents at
startup. It is possible that the startup current exceeds the over-current
trip level of the inverter. In this case the output voltage will shortly
decrease to limit the output current of the inverter. If the over-current
trip level is continuously exceeded, the inverter will shut down and
automatically restart within 20 seconds. In this case it is advisable to
disconnect this appliance from the inverter, since it requires too much
power to be driven by this unit. The ePRO Combi needs to be restarted
manually when it has shut down due to overloads for four times in a row.
Note that at higher ambient temperature levels, the overload capacity
of the ePRO Combi will be reduced.
