README
WARNING: Before you install and use your
VLT
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 VLT SERIES
Power Inverter as prescribed by Underwriters Laboratories (UL). The VLT SERIES inverters are designed to
be compliant with UL 458, Power Converters/Inverters and Power Converter/Inverter Systems.
NOTICE:
The output waveform of the VLT SERIES inverter is sinusoidal. Total harmonic distortion is
less than three 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 compart-
ment. 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 flam-
mable 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 dimin-
ished performance.
4. To avoid the risk of fire, electrical shock, or injury to persons, do not use attachments not recom-
mended or sold by Vanner Inc.
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.
