tbs electronics Powersine Combi PSC1800-24-30 Mode D'emploi page 15

On pins 1, 2 and 3 of the 7 pins screw terminal located in the connection compartment, both
normally closed and normally open contacts are available. Please make sure not to exceed
the maximum relay contact rating of 30V/1A or 60V/0.5A, in order to avoid damaging the
relay.
4.4 Trigger input (not available yet in firmware version 1.0.x)
The trigger input offers a way of externally controlling the behaviour of the Powersine
Combi. The trigger input can be connected to an external switch or a potential free relay
contact. Closing this external switch or contact, a user programmable 'action' will be
performed. Such an action could be to release the AC transfer switch, temporarily disable
the AC input Power Boost feature or force the Powersine Combi to switch to inverter mode.
All this can be configured in TBS Dashboard.
4.5 Load requirements in inverter mode
Before you connect your appliance(s) to the Powersine 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 overcurrent trip level of the inverter. In this case the
output voltage will shortly decrease to limit the output current of the inverter. If the
overcurrent 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 to much power to be driven by this unit. The
Powersine 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 Powersine Combi will be reduced.
