Important Safety Instructions
1. Before using the inverter, read all instructions and cautionary
markings on the unit, the batteries, and all appropriate sections of this
manual.
2. Use only attachments recommended or sold by the manufacturer.
Doing otherwise may result in a risk of fire, electric shock, or injury
to persons.
3. The inverter is designed to be permanently connected to your AC and
DC electrical systems. Xantrex recommends that all wiring be done
by a certified technician or electrician to ensure adherence to the local
and national electrical codes applicable in your jurisdiction.
4. 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 inverter with damaged or substandard wiring. See
Appendix, F “Multi-wire Branch Circuit Wiring” for information
about multi-wire branch circuits.
5. Do not operate the inverter if it has been damaged in any way. If the
unit is damaged, see the Warranty and Product Information section at
the end of this manual.
6. This unit does not have any user-serviceable parts. Do not
disassemble the inverter. See “How do you get service?” on page I–1
for instructions on obtaining service. Attempting to service the unit
yourself may result in a risk of electrical shock or fire. Internal
capacitors remain charged after all power is disconnected.
7. To reduce the risk of electrical shock, disconnect both AC and DC
power from the inverter before attempting any maintenance or
cleaning or working on any components connected to the inverter.
Turning off controls will not reduce this risk.
8. The inverter must be provided with an equipment-grounding
conductor connected to the AC input ground.
WARNING
This chapter contains important safety and operating instructions as
prescribed by UL and CSA standards for inverters used in residential
applications. Read and keep this Installation Guide for future reference.

9. Do not expose this unit to rain, snow, or liquids of any type. This
product is designed for indoor use only. Damp environments will
significantly shorten the life of this product and corrosion caused by
dampness will not be covered by the product warranty.
10. To reduce the chance of short-circuits, always use insulated tools
when installing or working with the inverter, the batteries, or the PV
arrays.
11. Remove all jewelry while installing this system. This will greatly
reduce the chance of accidental exposure to live circuits.
Explosive gas precautions
1. Working in the vicinity of lead acid batteries is dangerous. Batteries
generate explosive gases during normal operation. Therefore, you
must read this guide and follow the instructions exactly before
installing or using your inverter/charger.
2. To reduce the risk of battery explosion, follow these instructions and
those published by the battery manufacturer and the manufacturer of
the equipment in which the battery is installed.
