2.4.4 Before proceeding further, carefully check that the cables you have just connected to the negative terminal
of inverter are connected to the negative DC power source.
CAUTION!
Reverse polarity connection will blow a fuse in inverter and may
permanently damage the inverter.
Damage caused by reversing polarity connection is not covered
by our warranty.
2.4.5 Set the power switch to the ON position. After a moment you will hear three beeps. At the same time,
the display scrolls the word “TRANSTECTOR” twice. After that, you will hear a continuous sound from
internal alarm. When theAC output voltage shows on the display the unit will have completed the start-up
sequence.
2.4.6 Set the power switch to the OFF position. The unit should shut down completely.
2.4.7 To accurately measure the true output R.M.S. voltage of inverter connect to one of the outlet sockets and
then set the power switch to ON. Voltage will appear at the output sockets after the start-up sequence is
completed.
2.5 Safety Grounding
During the AC wiring installation, AC input and output ground wires are connected to the inverter. The AC input ground
wire must be connected to the incoming ground from your AC utility source.
The AC output ground wire should go to the grounding point for your loads (for example, a distribution panel of bus
chassis).
2.5.1 Neutral Grounding - 120V models only.
The neutral conductor of the AC output circuit of the Inverter is connected to the safety ground during
inverter operation. This conforms to national electrical code requirements that separately derived AC
sources (such as inverters and generators) which have their neutral conductors tied to ground in the same
way that the neutral conductor from the utility is tied to ground at the GFCI breaker panel. When AC utility
power is connected and the inverter is in bypass mode, this connection (neutral of the Inverter’s AC output
to input safety ground) is not present so that the utility neutral is only connected to ground at your breaker
panel, as required.
2.6 Making DC Connections
Follow this procedure to connect the battery cables or those from another DC source to the DC input terminals on the
Inverter.Your 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 drop across the cables from the inverter to the batteries / other
DC source.
The longer and narrower these cables, the greater the voltage drop.
WARNING!
The installation of a fuse must be on the positive cable.
Failure to place a fuse on [+] cables running between the
inverter and battery or other DC source may cause damage
to the inverter and will void the warranty.
Connections must not be made when the DC source is live.
Increasing your DC cable size will help to improve the situation.
TRANSTECTOR recommends the following cables for optimum inverter performance.
Model NUMBER
1kVA models Wire Size1 In-line Fuse Model NUMBER 2kVA models Wire Size1 In-line Fuse
ACINV1-1KVA #6AWG 40A ACINV2-2KVA #2AWG 70A
Notes:
1. Use only high quality copper wiring and keep cable length from 3-6 feet (~1-2m).
2. The maximum wire size that the black and red input connectors can accept directly is #2AWG.
Thesemodelsaresuppliedwithtwotypesofadaptorforuseindi󰀨erentapplications.Onetype
MUSTbettedintotheconnectorstoallowforthegreaterwiresizerequired.
A suitable breaker, at the DC source, for isolation and overload protection is recommend.
2.7 Alarm Connection
It is important to note that the electronic circuits associated with this function are directly connected within the
AC output circuits of the inverter and that for this reason the relay contact connections that are provided on the
rear panel mounted wire clamp connector MUST be considered to be at a non-SELV potential and all necessary
precautions to protect the operator from electric shock hazard must be taken.
These relay contacts must not be connected directly to any SELV or other safety connected circuit and any
cables or wiring used for such connections must be double insulated.
2.8 Inverter Operation
To operate the power inverter, turn it on using the ON/OFF switch on the front panel. The power inverter is now
ready to deliver AC power to your loads.
If you are operating several loads from the power inverter, turn them on separately after the inverter has been
turned on. This will ensure that the power inverter does not have to deliver the starting currents for all the loads
at once.
CAUTION!
EXTERNAL SURFACES GET HOT.
During the period of the unit running, the case may become very
warm. Please do not touch the side marked. “ ” directly.

These inverters are designed to operate from the following input voltage ranges:
42.0 to 62.0VDC
High and low DC input voltage conditions are handled per the following table and described in
more detail below:
Model
Type DC input OVP shut-down DC input OVP alarm DC input UVP shut-down DC input UVP alarm
48VDC 62.0VDC 61.0VDC 43.0VDC 42.0VDC
2.8.8 Over voltage protection indicator: (OVP)
When OVP is indicated on the display the unit has shut itself down due to the input voltage exceeding the
limits shown above.
2.8.9 Under voltage protection indicator: (UVP)
When UVP is indicated on the display the unit has shut itself down due to the input voltage falling below the
limits shown above.
2.8.10 Over temp protection indicator: (OTP)
When OTP is indicated on the display the unit has shut itself down because it has become overheated.
The unit may overheat because it has been operated at power levels above its rating, or because it has
been installed in a location which does not allow it to dissipate heat properly. The unit will automatically
restartonceithascooledo󰀨.
2.8.11 Overload protection indicator: (OLP)
When OLP is indicated on the display one of two conditions has occurred as follows:
a) For an overload condition approximately 110-120% of the WATTS rating of the unit and lasting up to
around 1 minute, an audible alarm will sound and the unit will continue to deliver power directly to the load.
If the overload condition continues the unit shuts itself down.
b) For a larger overload condition the unit shuts itself down immediately.
In both cases it is necessary to restart the unit once the overload has been removed.
In all of the above cases, if an AC utility supply is connected and the AC input breaker switched ON the load will be
automatically be transferred to the utility supply.
2.9 Cooling Fan Operation
The cooling fan management system monitors both the output power and internal temperature of the unit.
Thefanswillnotnormallyruniftheoutputpowerislessthan300W,unlesstheinternaltemperatureexceedsrecommended
norms.
In the event that the ventilation openings are obstructed the unit will enter over temperature protection mode (OTP) and
the cooling fan will continue to operate in order to reduce the internal temperature to a safe operating level. Once this
has been achieved the unit will turn on automatically.
3. Maintenance
ACINV Series inverters require only minimal maintenance for reliable operation.
The exterior of the unit should be cleaned down periodically with a dry cloth to prevent accumulation of dust and dirt,
paying particular attention to the ventilation openings.
Also,theDCinputterminalconnectionsshouldbecheckedtoensurethattheyaresu󰀩cientlytight.
4. Troubleshooting Guide

result.
  5.1.2 Toavoidariskofreandelectronicshock.Makesurethatexistingwiringisingoodelectricalcondition;and
that wire size is not undersized. Do not operate the Inverter with damaged or substandard wiring.
 5.1.3 Thisequipmentcontainscomponentswhichcanproducearcsorsparks.Topreventreorexplosiondonot
installincompartmentscontainingbatteriesorammablematerialsorinlocationswhererequireignition
protected equipment.
   This includes any space containing gasoline-powered machinery, fuel tanks, or joints, ttings, or other
connection between components of the fuel system.
5.2 Precautions When Working with Batteries
5.2.1 Ensure the installer is familiar with the material safety data sheet from the manufacturer of the batteries
concerning safe use and medical treatment.
  5.2.2 NEVERsmokeorallowasparkorameinthevicinityofbatteries.
5.2.3 Do not drop a metal tool on the battery. The resulting sparks or short-circuit on the battery or other electrical
part may cause an explosion.
5.2.4 Removepersonalmetalitemssuchasrings,bracelets,necklaces,andwatcheswhenworkingwithbatteries.
Lead-acid batteries produces a short-circuit current high enough to weld a ring or the like to metal, causing
severe burn.
6. DIP switch settings
ThefollowtablesdenethevarioussettingsoftheDIPswitchesmountedattheleftsideofthefrontpaneloftheInverter.
Note that when changes are made to these settings it is necessary to recycle the power to the Inverter to allow
the internal microprocessor to read the new settings.

7. Communications Protocol & Remote ON/OFF Function
ACINV series inverters can communicate their status to a computer via an RS232 connection by sending a single ‘Status
Inquiry’ Telnet command from the computer as follows.
UsingaTerminalprogrammesuchasHyperterminalcreateaprolewiththefollowingparameters:
Baud rate: to match setting on unit (default 2400)
Data bits: 8
Parity: none
Stop bits: 1
Flow control: none
From the properties tab (in Hyperterminal) settings and then ASCII and make sure that all boxes are checked with the
exception of ‘Force incoming data to 7-bit ASCII.
Makesuretheproleissavedforfutureuse.
