2.5 Connecting the load
Before you connect your appliance(s)
to the inverter, always check it’s maximum power
consumption. Do not connect appliances to the inverter needing more than the nominal
power rating of the inverter continuously. Some appliances like motors or pumps, are
drawing large inrush currents in a startup situation. In these situations, 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 this
overcurrent trip level is continuously exceeded, the inverter will shut down and restart
within 18 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 inverter. Note that at higher
ambient temperature levels, the overload capacity of the inverter is reduced.
CAUTION
NEVER CONNECT THE INV
ERTER’S OUTPUT TO TH
E AC DISTRIBUTION
GRID, LIKE YOUR HOUSEHOLD AC WALL OUTLET. IT WILL
PERMANENTLY DAMAGE THE INVERTER!
2.6 Activating the inverter
When all the above requirements are checked and satisfied and all connections are made,
it’s time to turn on your
Powersine inverter by pushing the power
switch in the ‘
I
’
position (see top label for push direction). After a short two tone beep (except PS200-xx
models), indicating that all internal circuits are checked, the sinewave shaped output
voltage is gently rising until 230V/50Hz
2% (or 115V/60Hz
3%) is reached.
When the inverter is not supplying
power to an appliance for a longer time, it’s
recommended to use the inverter in the "Auto Standby" (ASB) mode to heavily reduce
the inverter's own power consumption. In this case the power switch must be pushed in
the '
II
' position. In the ASB mode the inverter will generate a testpulse on it's output
once per second, to check if there is a load applied. When the ASB mode is activated (by
generating a reversed two tone beep, (except PS200-xx models), the indicator LED will be
continuously on for 4 seconds while the inverter outputs a continuous 230V (or 115V)
sinewave. After this 4 seconds the continuous output will change to a pulsed output,
indicated by a flashing indicator LED. When a load is connected to the inverter output (or
switched on) drawing more than approx. 5W, 12W or 15W (depending on model), the
inverter jumps to the continuous mode immediately, delivering power to the load. When
the load is disconnected again (or switched off), the indicator LED starts flashing again
after 4 seconds, and the inverter jumps back to the pulsed output ASB mode. This way
the inverter automatically jumps to a low power 'sleep' mode when there is no power
demand on the output.
