Introduction
1.5 Features – CMW412
The CMW412 inverter is equipped with the following front panel features
(see Figure 1-1):
1. Power Indicator – an at-a-glance LED that lights green when the inverter
is on. (see Section 3.0 Operation).
2. Fault Indicator – an at-a-glance LED that comes on to indicate an
inverter fault (see Section 4.0 for troubleshooting).
3. Serial Number – the unique identifi cation number assigned to each unit
(with a model-specifi c prefi x). Note: Enter your inverter’s serial number in
the table at the bottom of page i. It is to easier to record this information
now, instead of trying to gather it after the unit has been installed.
4. ON/OFF Power Switch – a 2-position switch that turns the inverter
on and off.
5. AC Outlets – two 15-amp AC outlets that accept standard plug-in power
cords to provide AC output to your loads.
6. Vents – ventilation openings that allow air fl ow through the unit—heated
air is removed by the internal cooling fan.

Figure 1-1, Front Panel Features (CMW412)
The back panel of the CMW412 inverter is equipped with the following
features (see Figure 1-2):
7. Cooling Fan – an intake cooling fan that automatically turns on when the
inverter’s internal temperature rises above 122°F (50°C). The fan turns
off when the inverter’s internal temperature falls below 122°F (50°C).
8. Model Number – the model number of the inverter (i.e., CMW412).
9. DC Positive Terminal (red) – the inverter’s connection to the positive
terminal on the 12 VDC battery bank.
10. DC Negative Terminal (black) – the inverter’s connection to the
negative terminal on the 12 VDC battery bank.
