Viewed from the left side of the Inverter module, access
holes can be seen for selecting the AC output voltage via a
120VAC/240VAC hard wired connector plug, and setting of
the MICRO CONTROL "DIP" switches. If low output voltage
is desired (100 to 120VAC) the jumper plug must be in the
120VAC position, toward the rear of the unit. If high voltage
output is desired (200 to 240VAC) then the jumper plug must
be removed and placed in the 240VAC position, side toward
the front panel. Also make sure the MICRO CONTROL
SELECT "DIP" switches 5 and 6 are set to the desired
voltage position. For 120VAC or 240VAC output, switch 5
must be OFF, switch 6 OFF. For 115VAC or 230VAC, switch
5 must be ON, 6 OFF. For 110VAC or 220VAC, switch 5 must
be OFF, 6 ON. For 100VAC or 200VAC, switch 5 must be
ON, 6 ON.
With the Static Transfer Switch option installed, the
frequency selected must be the same as the utility AC
frequency. If the Utility frequency is 60 Hz and the Inverter is
set for 50 Hz, the microprocessor can not phase lock to the
input, and consequently transfer from Inverter to Utility for
overload or Inverter shut down can not be accomplished
without causing transients on the output. During start up of
the Inverter, the load is always powered from the Utility and
upon transfer to the Inverter, the output voltage will transfer
at some unknown phase. So if 60 Hz operation is desired,
set the MICRO CONTROL SELECT "DIP" switch 7 to OFF
for 60 Hz, ON for 50 Hz.
If the Static Transfer Switch is installed, the MICRO
CONTROL SELECT "DIP" switch 3 must be set to the OFF
position. If the Static Transfer Switch option is not installed,
set this switch to the ON position.
If the Static Transfer Switch option is installed , either the ON
line (output from the Inverter) or OFF line (output from the
Utility power source) mode of operation may be selected. To
select the ON line (Inverter) mode, set MICRO CONTROL
SELECT "DIP" switch 8 to OFF. For OFF line (Utility)
operation, set switch 8 to ON.
Some users do not want the Inverter to automatically restart
upon application of DC power to the unit. Under this
condition, set the MICRO CONTROL SELECT "DIP" switch
4 to ON (manual restart required by turning the DC circuit
breaker OFF and then back to ON). If it is desired that the
Inverter automatically start up upon application of DC, the
MICRO CONTROL SELECT "DIP" switch 4 must be set to
the OFF position.
