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. Under some conditions, the GT Inverter heat sink can reach temperatures hot enough to cause skin
burns if accidentally touched. Ensure that the GT Inverter is located away from normal traffic areas.
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. Authorized service personnel should reduce the risk of electrical shock by disconnecting 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. Normally grounded conductors may be ungrounded and energized when a ground fault is indicated.
10. The GT Inverter must be connected to an AC equipment-grounding conductor directly and a DC
grounding electrode conductor to a single point ground.
11. The AC Neutral connection is for voltage sensing only and is not used as a current carrying conductor,
nor is it bonded to ground.
Observe the clearance recommendations as described on page 2–7. Do not install the GT Inverter in a zero-
clearance or non-ventilated compartment. Overheating may result.
WARNING
The following warnings identify conditions or practices that could result in personal injury or loss of life.
CAUTION
The following caution identifies conditions or practices that could result in damage to the unit or other
equipment.
