Installation
Connect the Chassis Ground
The PurePower 1800 inverter has a screw terminal labeled
CHASSIS GND on the outside of the rear panel as shown in Figure
3, “PurePower 1800 inverter Back Panel” on page 5.
Follow the guidelines below to connect the inverter’s chassis to the
ground.
Grounding Locations
The chassis ground terminal must be connected to a grounding
point. The grounding point varies depending on where you install
the PurePower 1800 inverter. Follow the guidelines that correspond
to your type of installation.
Connect The Battery Cables
To operate safely and effectively, the PurePower 1800 inverter
needs proper DC cables and DC-rated fuse(s). Because the
PurePower 1800 inverter has low-voltage and high-current input,
low-resistance wiring between the battery and the inverter is
essential to deliver the maximum amount of usable energy to your
load.
ELECTRICAL SHOCK HAZARD
Never operate the PurePower 1800 inverter without connecting it
to the ground.
Failure to follow these instructions will result in death or serious
injury.
Recreational
Vehicle
Connect the CHASSIS GND screw to the vehicle’s
chassis using a minimum 8 AWG copper wire
a
(preferably with green/yellow insulation).
Fixed Location Connect the CHASSIS GND screw to your system’s
DC grounding point using a minimum 6 AWG wire
a
.
The system’s grounding point is usually the AC
service entrance grounding point or a separate
ground rod. For a solar PV (photovoltaic)
installation, this is usually the same rod used to
ground the PV array.
a.It is recommended that the grounding conductor (grounding wire) should be the same wire size
as the DC cables.
IMPORTANT: Use of a qualified installer strongly recommended.
