Important Safety Instructions
SAVE THESE INSTRUCTIONS—This manual contains important instructions that shall be followed
during the installation and maintenance of the Xantrex Grid Tie Solar Inverter.
1. Before installing and using the GT Inverter, read all instructions and cautionary markings on the
inverter, wiring box, and all appropriate sections of this guide.
2. To reduce risk of fire hazard, do not cover or obstruct the heat sink.
3. Observe the clearance recommendations as described on page 2–18. Do not install the GT Inverter in a
zero-clearance or non-ventilated compartment. Overheating may result.
4. Use only accessories recommended or sold by the manufacturer. Doing otherwise may result in a risk
of fire, electric shock, or injury to persons.
5. To avoid a risk of fire and electric shock, make sure that existing wiring is in good condition and that
wire is not undersized. Do not operate the GT Inverter with damaged or substandard wiring.
6. Do not operate the GT Inverter if it has received a sharp blow, been dropped, or otherwise damaged in
any way. If the GT Inverter is damaged, see the Warranty section.
7. Do not disassemble the GT Inverter. It contains no user-serviceable parts. See Warranty for instructions
on obtaining service. Attempting to service the GT Inverter yourself may result in a risk of electrical
shock or fire and will void the factory warranty.
8. To reduce the risk of electrical shock, disconnect both AC and DC power from the GT Inverter before
attempting any maintenance or cleaning or working on any circuits connected to the inverter. Turning
off controls will not reduce this risk. Internal capacitors remain charged for 5 minutes after
disconnecting all sources of power.
9. The GT Inverter must be connected to an equipment-grounding conductor directly or via the AC
ground.
