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 the AC 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.

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 different applications. One type
MUST be fitted 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. "
