SureSine Inverter Quick Start Guide
Power UP Sequence:
1. Connect Battery/Battery Bank. (STEP 11)
2. Close all circuit breakers, disconnect switches, or insert
fuse into fuse holder. (STEP 12)
3. Put the AC Output Mode Switch in the ON (or REMOTE)
position. (STEP 13)
Power DOWN Sequence:
1. Put the AC Output Mode Switch in the OFF position.
2. Open all circuit breakers, disconnect switches, remove
fuses from fuse holders.
3. Disconnect Battery/Battery Bank.
Mounting:
Minimum
Clearance
Requirements:
CAUTION: Equipment Damage
Do not expose the SureSine to weather. Locate
in a dry, protected area to prevent equipment
damage.
Ensure the minimum clearance requirements are
followed to provide adequate ventilation and
prevent the unit from overheating.
IMPORTANT: Example only. Actual wiring may vary. READ the SureSine
Installation and Operations Manual for mandatory safety requirements. All
configurations must comply with local and national electric codes. Consult the
local electric authority to ensure compliance.
WARNING: Risk of Fire
Do not install over an easily combustible
surface, since the heat sink may get hot
under certain operating conditions.
Step 1: Choose mounting location
A) Determine how and where the inverter will be mounted.
B) Ensure the inverter is protected from sun, rain, and dust.
Step 2: Wiring accessibility and air flow clearance
A) Plan and confirm wire routing-access.
B) Verify that the mounting screws will not penetrate wires or
other objects located on the opposite side of the surface.
C) Verify that there is at least 6" of space around the unit.
Step 3: Mark and drill holes
A) Place the inverter on the wall where the unit will be mounted.
B) With a pencil or pen, mark the center of each keyhole slot;
two (2) on top and two (2) on the bottom.
C) Remove the inverter and drill four (4) 1/8" (3.175 mm) holes
where the marks were made.
Step 4: Secure the inverter
A) Place the SureSine onto the surface and align the keyhole slots
with the four (4) pilot holes.
B) Use the four (4) #10 screws (included) to secure the SureSine to the surface.

2BEFORE INSTALLING:
Ensure the fuse is removed from
the fuse holder or the disconnect
is in the OPEN position.
WARNING: Shock Hazard
Fuses, single-pole circuit breakers or single-pole
disconnect switches should NEVER open
grounded system conductors. This could create a
shock hazard that could be fatal to personnel
and/or damage the equipment.
CAUTION: Equipment Damage
Ensure the AC loads do not exceed the continuous
and surge power ratings.
WARNING: Risk of Fire
All over-current protection devices and wiring must
be sized properly, in accordance with US National
Electric Code (NEC) or the country of installation’s
local regulations.
WARNING: Explosion Hazard
Never install the SureSine in an enclosure with
vented/flooded batteries. Battery fumes are
flammable and will corrode and destroy the
SureSine circuits. Ensure sufficient ventilation.
For optimal ventilation
and cooling, mount in
portrait style orientation.
CAUTION: Burn Hazard
Place in a location to avoid
direct contact.

Ensure the inverter chassis
is properly bonded to
ground as per Section 2.8.4
of the installation manual.
IMPORTANT: Neutral-Ground
Bond
The AC Neutral of the 120 Vac/ 60 Hz models is
bonded to the inverter frame internally from the
factory as required for UL safety requirements.
The AC Neutral of the 127 V, 230 V, and 240 V
models is floating (not bonded to the inverter
frame). If a neutral-ground bond is required an
internal neutral-ground jumper wire (included) can
be used to connect the neutral terminal to the
grounded chassis.
Ensure there is only 1 Neutral-to-Ground Bond
in the entire system.
Consult Section 2.8.4 of the manual for additional
information.
