Instructions
Retain these instructions for future reference.
Overview
The Pure Sine Wave (PSW) inverter provides a 230V supply which closely replicates the domestic mains supply. This makes it ideal for powering more sensitive equipment which may not be compatible with traditional Modified Sine Wave (MSW) inverters.

CAUTION
There may be sparks produced when making battery connections, ensure no flammable materials are present. Incorrect connection of cables to the battery (reverse polarity) may damage the unit and is not covered by the warranty.
Single Battery System
Dual Battery System
For heavy-duty applications, a secondary battery can be fitted to increase the inverter running time. An additional relay may also be fitted to allow this battery to be charged from the vehicle alternator when the vehicle engine is running, Fig2 shows an example installation.
Earth Connection
Ensure the inverter is earthed by connecting a cable from the inverter earthing bolt N to suitable earth within the installation (normally the vehicle chassis).
- It is recommended the inverter is wired and tested by a qualified electrician
- Ensure that the inverter power on/off switch is in the OFF (0) position.
- Remove 2 x screws holding LCD in position
- Pull LCD forwards and unclip the data connector from the circuit board
- Connect 6 metre extension lead to the circuit board
- Fit blanking plate and fix with 2 x screws, a slot is provided for cable to exit
- Fix LCD into the mounting frame using 2 x screws
- The fit frame where the display is required and attach 6-meter cable to rear
- Snap-fit endplates to cover screw fixings
- Turn the power on/off switch to the ON (I) position.
- The inverter can now be controlled remotely from the LCD display
- Adding an LCD Display (600W Model)
- An LCD display can also be added to models without this function by using the optional LCD Display & Frame Kit
- Connect the 6-meter extension lead to display port J on the inverter
- The fit frame where the display is required and attach the 6-meter cable to rear
- Snap-fit endplates to cover screw fixings
- Turn the power on/off switch to the ON (I) position.
- The inverter can now be controlled remotely from the LCD display
Current Sensor Installation (optional)
To enable monitoring of the input current and hours remaining function, the optional current sensor should be fitted as shown in Fig4
- Using a black battery cable supplied with an inverter, attach one end to battery(-) terminal and another end to batt(-) terminal on Current Sensor
- Using a red battery cable supplied with an inverter, attach one end to the battery(+) terminal and another end to the inverter(+) terminal
- Now connect cables 1-4 (supplied with current sensor) as shown in Fig4
- Load(-) cable,
- Comms cable,
- +12V Power cable,
- Temperature sensor cable,
- negative connection from the inverter to the sensor
- Use 1x4AWG cable for 600/1000W models
- Use 2x2AWG cable for 2000/3000W models
- data connection from sensor port K on the inverter to current sensor 12V power supply to sensor temperature compensation for a more accurate current reading
Operation
Switching On
- Ensure that the inverter power on/off switch is in the OFF (0) position.
- Plug the appliance into the AC output socket on the inverter, ensuring it does not exceed the maximum output power of the inverter
- Turn the power on/off switch to the ON (I) position.
- The Power indicator will illuminate green and main power will be available from the AC output socket(s). On models fitted with a display, the LCD screen will also illuminate.
LCD Display & Indicators
Where fitted the LCD display provides additional information to help monitor and manage power from the inverter.
Information Mode
Various information modes are available by pressing up/down b to move forward or backward through the screens.
- Input voltage available from the battery supply.
- Input current is being used from the battery supply in order to power the load. *The optional Current Sensor must be fitted to enable measurement of input current.
- Output voltage available from the AC outlets.
- Output power being consumed by the connected loads.
- An estimate of the time remaining before the battery will be depleted based on the current load.
- *The optional Current Sensor must be fitted to enable measurement of hours remaining.
Setup Mode
The inverter can be configured by entering the setup mode To enter Setup Mode press & hold key Press V keys to select item then press,chosen setting will then flash Adjust setting using AV then press to set Press and hold key to exit back to Information Mode.
- Sets the AC output voltage. Only change if the application requires a different voltage for optimum performance
- Allows the last error code to be viewed
- Sets the Ah rating of the battery supplying the inverter. The value is used when calculating input current and hours remaining in conjunction with the Current Sensor Power Saving Mode If the inverter does not detect a load for 10 minutes it will enter a sleep mode to reduce the drain on the battery. In this mode, the power indicator will flash green
- Low Voltage Cut-Off Sets the voltage at which the inverter will switch off should the input voltage become too low
- Sets the output frequency of the inverter. Only change if the application requires a different frequency for optimum performance
- Tests the earth leakage protection function is working correctly.
- This test should be carried out at least every three months.
Indicator & Error modes
Power
- Illuminates green to show the unit is switched on and power is available from the AC output socket(s)
Overload
- Illuminates red if the unit has been overloaded due to excessive current or a short circuit
Over Temperature
Illuminates yellow if the unit has overheated
Audible Alarm
An alarm sound will be heard if the unit has switched off due to a fault
AC transfer function: In the front panel “AC INPUT” is connected, and the unit will switch to the external current supply automatically. The power discharge from the battery will be stopped. This state will be indicated by 3 (Green- Red-Yellow) light-emitting diode (LED), Flash every 2 seconds. As long as the mains voltage is supplied, the inverter can not be restarted. AC transfer time < 0.1s Inverter will start SLEEP MODE in 10 min.
Earth Leakage Protection
To provide protection in the event of a fault, the 230V outlets on this
inverter are protected by an integral Residual Current Device (RCD). Should a
fault occur the inverter will switch off to protect all connected circuits and
display an error code.
Note: The RCD function must be tested at least every three months to ensure it
trips correctly, this can be done in two ways:-
- Enter Setup Mode > RCD > Press 8 key
- From Information Mode, press and hold ‚ or key for 3 seconds
- If the RCD function is OK, the inverter will trip and PASS will be displayed.
- If RCD does not trip correctly FAIL will be displayed, if this happens the inverter should not be used until it has been checked by a qualified electrician.
RCD Tripping current: 30 mA
