CSW1012 and CSW2012 Operation
The CSW1012 and CSW2012 inverters use a front panel that contains a
power/select button, a status indicator, a digital display for viewing system
status, a remote port, a USB port, and a GFCI AC output receptacle.
Turning the Inverter on and off
The Power/Select button is used to turn the inverter on and off. To turn the
unit on, press and hold the button for 1 second until you hear a “beep”. The
digital display alternately shows the unit’s measured battery voltage and AC
output power, and the status indicator lights green. Press the power/select
button to turn the unit off.
WARNING:
The power/select button is not a power disconnect
switch and will not remove the DC power from the inverter.
Disconnect all power to the inverter before working on the inverter.
Status Indicator
The Status indicator on the front panel may light green, amber, or red to
indicate the inverter’s status. When the status indicator lights:
• Green
– the inverter is operating normally.
• Amber
– a warning has been detected. The inverter will shut down at
any time. Check the error code on the digital display.
• Red
– an error has been detected and the unit has shut down. Check
the error code on the digital display.
When the status indicator lights amber or red, use the digital display and the
troubleshooting tables in Section 4.0 to resolve the issue.
Digital Display
The Digital Display has one line of three alphanumeric characters that
alternately shows the inverter’s measured battery voltage (in volts) and
AC output power (in kilowatts) under normal operating conditions. It also
displays error/warning codes that alert you to problems with the unit, and
are used in conjunction with the troubleshooting tables in Section 4.0 to
resolve any issues with the inverter’s operation. See Table 3-1 below.
Table 3-1, Examples of Digital Display Readings
Display
Meaning
12.5
Measured battery voltage.
0.80
Total AC output power in kW (800W as shown).
E01
Error or warning code. See Troubleshooting section for details.
Remote Port
The Remote Port is used to connect an optional ON/OFF remote switch (sold
separately) that works in parallel with the power/select button.
USB Port
The USB Port enables you to power and charge a USB-enabled device
(provides 5 VDC/750 mA).
CAUTION:
Some USB-powered products may be damaged when
connected to this USB port. If in doubt, check with the product’s
manufacturer.
GFCI Outlet
The two GFCI-protected AC outlets are used to plug in and power an AC load.
It protects the user against hazardous electrical shocks.
