1.0 Introduction
The back panel of the CSW1012 inverter is equipped with the following
features:
8. 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).
9. DC Negative Terminal (black) – the inverter’s connection to the nega-
tive terminal on the 12 VDC battery bank.
10. DC Positive Terminal (red) – the inverter’s connection to the positive
terminal on the 12 VDC battery bank.
11. Model Number – the model number of the inverter (i.e., CSW1012),
and regulatory compliance information.
12. DC Chassis Ground Screw – the connection that is used to tie the ex-
posed chassis of the inverter to the DC grounding system. The grounding
screw (8-32 x 3/8 Phillips PH) either connects to the vehicle’s chassis, to
the DC grounding bus, or to the engine’s negative bus.
13. Mounting Flanges (front and rear) – used to mount and secure the
inverter to a shelf/wall.
