FAQ:

1. Can the SureSine Inverter charge batteries?
   No, the SureSine Inverter is designed for converting DC power to AC power only. It does not have battery charging capabilities.

2. What are the available communication options for the SureSine Inverter?
   The SureSine Inverter offers AC Interface Options including Remote Switch, USB, EIA-485 and 12 V / 1 W auxiliary power, MS-CAN, and Bluetooth.

3. How do I set the Low Voltage Disconnect (LVD) on the SureSine Inverter?
   The LVD can be set using DIP Switch 5. The OFF position corresponds to a preset value of 10.5 V (for 12 Vdc), 21.0 V (for 24 Vdc), or 42.0 V (for 48 Vdc). The ON position corresponds to a preset value of 11.5 V (for 12 Vdc), 23.0 V (for 24 Vdc), or 46.0 V (for 48 Vdc).

In the Box:

Tools Required

• 2 Philips Screwdriver

• 3/16 (5 mm) & 1/8″ (3.8 mm) Flathead
• Screwdriver
  • Drill with a 1/8″ (3.8 mm) bit
  • Multimeter
  • Crimping Tool
  • Wrench

Minimum Clearance Requirements:

• WARNING: Risk of Fire
  Do not install over an easily combustible surface, since the heat sink may get hot under certain operating conditions.

• CAUTION: Burn Hazard
  Place in a location to avoid direct contact.

• 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.

• 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.

Mounting

1. Step 1: Choose mounting location
2. Determine how and where the inverter will be mounted.
3. Ensure the inverter is protected from sun, rain, and dust.
4. Step 2: Wiring accessibility and air flow clearance
5. Plan and confirm wire routing-access.
6. Verify that the mounting screws will not penetrate wires or other objects located on the opposite side of the surface.
7. Verify that there is at least 6″ of space around the unit.
8. Step 3: Mark and drill holes
9. Place the inverter on the wall where the unit will be mounted.
10. With a pencil or pen, mark the center of each keyhole slot; two (2) on top and two (2) on the bottom.
11. Remove the inverter and drill four (4) 1/8″ (3.175 mm) holes where the marks were made
12. Step 4: Secure the inverter
13. Place the SureSine onto the surface and align the keyhole slots with the four (4) pilot holes.
14. Use the four (4) #10 screws (included) to secure the SureSine to the surface.

TERMINAL TORQUE REQUIREMENTS

Terminal| **Terminal Size or Wire Size*| Torque to:**
In-lbs.| Nm
DC (+) (–) Input Bolt Terminals| M6 (~1/4″)| 35| 4
AC Output Neutral, Line and Ground Terminals| M6 (~1/4″)| 20| 2.3
Chassis Ground Lug| 14 – 2 AWG (2.5 – 10.0 mm2)| 35| 4
Modbus, Remote Switch, Auxiliary Power Terminals| 16 – 28 AWG (1.0 – 0.1 mm2)| 5| 0.57

• For recommended/minimum wire sizes and disconnect/fuse sizes per application, and terminal block installation for the remote switch or communications options, see the SureSine Installation and Operations Manual.

IMPORTANT:

• Example only.
• Actual wiring may vary.
• READ the SureSine Installation and Operator Manual for mandatory safety requirements.
• All configurations must comply with local and national electric codes.
• Consult the local electric authority to ensure compliance.

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.

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.
