Connections
WARNING: SHOCK HAZARD
This unit is not provided with a GFDI device. This inverter must be used with
an external GFDI device as required by the Article 690 of the National Electrical
Code for the installation location.
CAUTION: EQUIPMENT DAMAGE
• AC loads should not exceed the continuous and surge power ratings.
Exceeding these ratings could cause a fault and shut off the inverter. Loads
that have inrush currents that can exceed the highest power surge current
rating could damage the inverter.
• There are many types of loads that have high starting surges including
pumps, fans, refrigerator or air conditioner, air compressors, electric motors,
switched mode power supplies, and power tools. These loads can have a
power surge of 2 to 5 times the running power of the load or even higher. If
the manufacturer does not provide a surge rating for the load, check with the
manufacturer or multiply the maximum power by an appropriate sizing factor
for the type of load being used. If there are other loads in the system, the
surge power requirement must be added to the total running power of the
other loads in the AC system.
• Observe AC output voltage and frequency markings on the SureSine. Be sure
AC loads are compatible for proper load operation and to avoid damage to
loads and/or inverter.
Models which include AC terminals require permanent, hardwired AC
connections. This may require additional hardware such as sub-panels,
circuit breakers, fuses, disconnect switches or ground-fault circuit interrupter
(GFCI) breakers or outlets.
AC wiring must comply with local regulatory
code for the specifi c site.
No additional AC wiring is required with models that come factory wired
with an AC outlet. A Ground Fault Interrupter power strip or plug-in outlet
is recommended.
