README
WARNING: Before you install and use your IT SERIES AC Power Inverter, be
sure to read and save these safety instructions.
This manual contains important safety and operating instructions for the Vanner Power Group IT SERIES
Power Inverter as prescribed by Underwriters Laboratories (UL). The IT SERIES inverter is listed as
compliant with UL 458, Power Converters/Inverters and Power Converter/Inverter Systems, and UL 1741
Power Conditioning Units for use in Residential Photo-voltaic Power Systems. The IT SERIES is also
listed in the Canadian National Standard CSA – C22.2 No. 107.1957.
NOTICE:
The output waveform of the IT SERIES inverter is sinusoidal. Total harmonic distortion is
less than four percent.
CAUTION:
Read owners manual BEFORE wiring or powering up.
CAUTION:
Not intended for DC input directly from a solar array. Batteries must be used.
CAUTION:
DO NOT cover or obstruct ventilation openings. DO NOT mount in a zero-clearance
compartment. Overheating may result.
WARNING:
Under high ambient temperature / high-power-output conditions some parts of the
inverter may become hot enough to cause burns. The unit should be installed so that it is
not to be contacted by personnel.
WARNING:
This equipment employs components that tend to produce arcs and sparks. To prevent
fire or explosion, DO NOT install in confined areas or compartments that contain batteries
or flammable materials.
WARNING:
Improper use of this product may result in risk of electrical shock. Both AC and DC
voltage sources are terminated inside this equipment.
Use only the ground fault circuit interrupter (GFCI) receptacle(s) or circuit breaker(s)
specified in the installation and operating instructions. Other types may fail to operate
properly when connected to this equipment.
DANGER:
Battery connections are for disconnect only, NOT for current interruption.
General Precautions
1. Do not expose the inverter to direct water spray or snow.
2. To reduce the risk of a fire hazard, do not cover or obstruct the ventilation openings.
3. Do not install the inverter in a zero clearance compartment. This may result in overheating or
diminished performance.
4. To avoid the risk of fire, electrical shock, or injury to persons, do not use attachments not
recommended or sold by the Vanner Power Group.
5. Vanner recommends that all AC and DC electrical wiring be performed by a licensed electrician or a
qualified technician to ensure compliance with all applicable national and local wiring regulations.
6. To avoid a risk of fire and/or electrical shock, always verify wiring connections are in good electrical
condition. All external conductors must use proper wire size to avoid dangerous overheating or
diminished performance.
7. If the inverter has been dropped or damaged in any way, do not operate the inverter until it has been
verified to be safe by a qualified technician.
