Important safety instructions

WARNING

Limitations on use - The Eaton Inverter is not to be

connected to life support devices.

WARNING

Explosion hazard - Working with batteries can be very

dangerous. It is crucial to follow all steps completely
while servicing the unit. It is possible for the inverter to
produce arcs and/or sparks, do not install or use inverter
near flammable materials (i.e. gas- powered machines,
fuel tanks, or any components connected to a fuel supply).
Follow any instructions from the battery manufacturer being
used.

CAUTION

Risk of injury - To avoid risk of injury, use only 12Vdc, lead-

acid, rechargeable batteries (i.e. GEL, AGM, and Flooded).
Other types of batteries may burst, resulting in personal
injury and/or damage.

IMPORTANT

Do not cover/obstruct ventilation systems.

•

Use wire in good condition and of appropriate ratings.

•

Attachments not recommended by Eaton may be

•
damaging to inverter.

Do not use inverter after being dropped, hit, or

•
damaged.

Do not disassemble the inverter. Risk of shock, fire,

•
and void of warranty may result.

Remove all AC and DC connections before

•
maintenance, cleaning, or circuit work.

Provide inverter an equipment-grounding conductor

•
connected to AC input ground.

Insure cables are routed properly, secured and

•
protected from chaffing.

WARNING

Failure to follow these instructions could result in death,
personal injury or property damage.

Personal precautions when working with
batteries

WARNING

Risk of electrical shock, burn from high short-circuit
current, fire or explosion from vented gases.

• Follow the instructions and precautions from the
battery manufacturer (i.e. cap removal, or charging
rates).

• Follow battery instructions for water and battery acid
levels from the battery manufacturer.

• Ventilate the area near the batteries as much as
possible.

• Do not smoke or produce flame/spark near engine or
batteries.

• Use caution when handling tools around batteries.

• Remove all metal items (i.e. rings, bracelets, watches)
from person when working with batteries.

• Work within voice range of other people.

• Wear eye and clothing protection while working, and
avoid touching eyes during installation.

• Upon battery acid contacting skin or clothing, wash
immediately with soap and water.

• Upon contacting eye(s), flood immediately with running
cold water for at least twenty minutes and seek
medical attention.

CAUTION

DC connection precaution(s) - Make only DC output

connections or disconnections after setting all unit switches
to OFF position and opening AC disconnect(s).

CAUTION

Hard wired AC output connection caution - Always use

an external GFCI with hard wired AC output. WARNING:
Risk of electrical shock. Use only 20A rated GFCI receptacle
with UL listing.

NOTES

It is recommended to review TMC RP 160 and RP 163,
which include wiring and selection recommendations.

Introduction

Introduction

The Eaton Inverter is designed to create 1.8kW of pure sine wave 115VAC 60Hz power from a 12V battery source. The units
low THD (<2.5% typical) can power sophisticated electronics that may not work with modified sine wave inverters. Unit also
has high surge capability to power up hard to start loads like power tools, refrigerators or pumps.

The Eaton Inverter is protected against most abnormal conditions found in the automotive environment.

The unit has an under voltage alarm and shut down that prevents the batteries from becoming depleted.

A warning alarm will sound when the maximum power output is being reached. An alarm will also sound if unit is
overheating. If any of these conditions are not corrected, the unit will turn off safely to protect itself.

Some models include a three stage temperature compensated battery charger that maximizes the life of the batteries. It can
be configured for AGM, flooded or Gel lead acid batteries.

Eaton inverters include a Shore Power bypass feature. When AC power (Shore Power) is detected at the AC input, the unit
powers all accessories from this available power source. If the inverter automatically detects that AC input is removed, it
becomes an independent AC supply.

Inverter input current could be as high as 200A in the 1.8KW unit. Special care has to go into evaluating the proper sizing of
batteries, wire gauge and length.

The inverter’s logic is powered by the 12V input battery. The unit current draw when power is off is typically less than 2mA.
When the inverter is turned on with no load connected to its output it will typically draw less than 0.5A.

Operation efficiency is input voltage, load and ambient temperature dependent, but it is typically 90%.

The Eaton inverter will not withstand reverse polarity. Permanent damage will occur and is not covered by warranty.

Configuration guide

This chapter describes inverter operation, configuration and the meaining of error codes.

Setting battery types on main unit (models with battery charger only)

The inverter can operate from and recharge several different types of lead-acid batteries. It is important to make sure the bat­tery type is configured on the unit for optimum charging process before installing batteries. See Table 1.

Customizing display, alarm and charging current settings

The display panel is capable of adjusting the following:

• What is presently displayed on the screen

• Modify the charging current

• Enable/Disable the inverter output

• Enable/Disable the audible alarm

• Modifying the shutdown voltage value

• Select battery type for charging
