connected to the product.
This unit is designed for indoor use only. Do not expose the product to rain or snow; install only in a clean, dry
environment.
CAUTION – To reduce the risk of fire hazard, do not cover or obstruct the ventilation openings. Do not install the
inverter in a zero-clearance compartment.
CAUTION – Unless otherwise noted, use of an attachment not recommended or sold by the product manufacturer
may result in a risk of fire, electric shock, or injury to persons.
CAUTION – Do not operate the product if it has received a sharp blow, it has been dropped, or otherwise
damaged in any way – return it to a qualified service center for repair.
CAUTION – Do not disassemble the product – call our qualified service centers for servicing. Incorrect
reassembling may result in a risk of electrical shock or fire.
CAUTION – The AC Neutral Output is floating when the unit is powered by Batteries while in Invert Mode. Ensure
that any electrical equipment, connected as a load, is properly grounded.
WARNING – The input and output voltages of the product are hazardous. Extreme caution should be maintained
when servicing or touching conductive components connected to the product.
Mechanical Safety
Power equipment can reach extreme temperatures under load.
Use caution around sheet metal components and sharp edges.

Electrical Safety
WARNING
To avoid a risk of fire and electric shock, make sure that existing wiring is in good condition and
that wire is not undersized. Do not operate the inverter with damaged or substandard wiring.
Before working with any live battery or power system, follow these precautions:
•Remove all metallic jewelry; e.g., watches, rings, metal rimmed glasses, necklaces.
•Wear safety glasses with side shields (and prescription lenses if necessary) at all times during installation.
•Use OSHA approved insulated hand tools.
Do not work alone under hazardous conditions.
Ensure no liquids or wet clothes contact internal components.
Battery Safety
Servicing and connection of batteries shall be performed by, or under the direct supervision of, personnel
knowledgeable of batteries and the required safety precautions.
Never reverse DC+ and DC- to battery.
Keeps the battery away from heat sources including direct sunlight, open fires, microwave ovens and high-voltage
container. Temperatures over 60ºC may cause damage. Make sure the area around the battery is well ventilated.
Always wear eye protection, rubber gloves, and a protective vest when working near batteries. Remove all
metallic objects from hands and neck.
Use OSHA approved insulated hand tools. Do not rest tools on top of batteries.
Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
Batteries contain or emit chemicals known to the State of California to cause cancer and birth defects or other
reproductive harm. Battery post terminals and related accessories contain lead and lead compounds; wash hands
after handling (California Proposition 65).
If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters your eye,
immediately flood it with running cold water for at least twenty minutes and get medical attention immediately.
If you need to remove a battery, always remove the grounded terminal from the battery first. Make sure all
accessories are off so you don’t cause a spark.
WARNING
Follow battery manufacturer’s safety recommendations when working around battery systems.
WARNING
Do not smoke or present an open flame when batteries (especially vented batteries) are on
charge. Batteries vent hydrogen gas when on charge, which creates an explosion hazard.
Batteries are hazardous to the environment and should be disposed of safely at a recycling facility. Consult the
battery manufacturer for recommended local authorized recyclers.
Wiring Requirements

2 Inspection
2.1 Packing Materials
All Alpha products are shipped in rugged, double walled boxes and suspended via solid inserts to minimize shock
that may occur during transportation. Packaging assemblies and methods are tested to International Safe Transit
Association standards.
2.1.1 Returns for Service
Save the original shipping container. If the product needs to be returned for service, it should be packaged in its
original shipping container. If the original container is unavailable, make sure the product is packed with at least
three inches of shock-absorbing material to prevent shipping damage.
NOTE: Alpha Technologies is not responsible for damage caused by the improper packaging of returned products.
2.2 Check for Damage
Prior to unpacking the equipment, perform a visual inspection and note any damage. Unpack the equipment and
inspect the exterior for damage. If any damage is observed contact the carrier immediately.
In addition to the inverter module (Figure 1), the mounting kit provided consists of:
4 x M4 screws to connect the brackets to the cabinet:
23” mounting brackets:
Parallel signal port cover:
Continue the inspection for any internal damage. In the unlikely event of internal damage, please inform the
carrier and contact Alpha Technologies for advice on the consequence of any damage.
Verify that you have all the necessary parts per your order for proper assembly.
Call Alpha Technologies if you have any questions before you proceed: 1 [phone]

3 Installation and Wiring
3.1 Where to Install
The power inverter should be installed in a location that meets the following requirements:
•Dry: Do not allow water to drip or splash on the inverter.
•Cool: Ambient air temperature should be between -20°C and 60°C.
•Safe: Do not install in a battery compartment or other areas where flammable fumes may exist, such as fuel
storage areas or engine compartments.
•Ventilated: Allow at least three inches of clearance around the inverter for airflow, ensuring that the
ventilation openings on the front, rear and top of the unit are not obstructed.
•Dust Free: Do not install the inverter in a dusty environment where dust, wood particles or other
filings/shavings are present that may be pulled into the unit when the cooling fan is operating.
•Close to Batteries: Avoid excessive cable lengths but do not install the inverter in the same compartment as
batteries. Use the recommended wire lengths and sizes (see section 3.5).
Avoid mounting the inverter where it may be exposed to the gases produced by the battery. Prolonged exposure
to these corrosive gases will damage the inverter.
3.2 Unit Installation
The unit is pre-installed with 19-inch rack brackets. Put the unit to the rack horizontally, and align holes of
mounting brackets and rack. Secure the unit in position with four cross-pan type nickel screws.
3.3 Unit Removal
The unit can be removed from the equipment rack by screwing off the retaining screws.
3.4 AC Safety Grounding
During the AC wiring installation, AC input and output ground wires are connected to the inverter. The AC input
ground wire must connect to the incoming ground from your AC utility source.
The AC output ground wire should go to the grounding point for your loads.
WARNING
Do not operate the unit without connecting it to ground. Electrical shock hazard may result.

3.5 DC Wiring Connections
Connect the cables to the power input terminals on the rear panel of the unit.
【＋】is positive, and【－】is negative. Insert the cables into the terminals and tighten the nut to securely clamp
the wires.
Figure 2–DC input terminals
WARNING
Before proceeding, confirm that DC input cable connect correctly.
Make sure that all DC connections are tight (torque to 9-10 foot pounds). Loose connections will
overheat and could result in a potential hazard.
Follow this procedure to connect the battery cables to the DC input terminals on the unit.
The cables should be as short as possible (ideally, less than 10 feet / 3 meters) and large enough to handle the
required current in accordance with the electrical codes or regulations applicable to your installation. Cables that
are not an adequate gauge (too narrow) or are too long will cause decreased inverter performance such as poor
surge capability and frequent low input voltage warnings and shutdowns. These low input voltage warnings are
due to DC voltage drip across the cables from the inverter to the batteries. The longer and narrower these cables,
the greater the voltage drop.
CAUTION – Increasing your DC cable size will help improve the situation.
NOTE: We recommend #6 AWG 40A cables (48Vdc input) for optimum inverter performance (applies to both 110V and
220V series). Use only high quality copper wiring and keep cable length short (from 3-6 feet).
