tage of delivered out-

put power. The power 

bar turns red if more 

than nominal output 

power is presently 

being delivered.

note 1 : 

DC errors are too low or too high battery voltage and too high input ripple voltage. A

ripple voltage error can be caused by a too small battery, too long battery cables, bad DC

connections or too small battery cable wire gauge.

note 2 : 

Operating in DC error mode, the inverter restarts automatically when the battery voltage

returns to the normal inverter input voltage range again. If the DC error is caused by an

input ripple voltage error, the inverter needs to be restarted manually. Operating in output

overload or short circuit error, the inverter automatically restarts after 20 seconds.

Operating in high temperature error, the inverter restarts automatically when the inverter

temperature has reached a normal temperature level again. All error types are allowed

maximal four times in a row within a certain time period. When more than four errors are

counted within this time period, the inverter remains operating in an error mode and

needs to be restarted manually.

When the inverter is not supplying power to an appliance for a longer time, it is 

recommended to use the inverter in the "Auto Standby" (ASB) mode to heavily reduce the 

inverter's own power consumption. In this case the power switch must be pushed in the 

“II” position. In the ASB mode the inverter will generate a testpulse on it's output once per 

second, to check if there is a load applied. When a load is connected to the inverter output 

(or switched on) drawing more than approx. 20W, the inverter jumps to the continuous 

mode immediately, delivering power to the load. When the load is disconnected again (or 

switched off), after 4 seconds the inverter jumps back to the pulsed output ASB mode. 

This way the inverter automatically jumps to a low power mode when there is no power 

demand on the output.

Note that some loads like TV/video equipment (with standby mode) and alarm clocks need 

continuous power so that the ASB mode can not be used. With some small non 

compensated loads, it is possible that the inverter jumps from continuous output to pulsed 

output and vice versa all the time. In this case you will have to connect a small additional 

load to the AC output.

4. Acoustical alarms

To warn you before the inverter might shut down, the inverter is equipped with an 

acoustical alarm. There are three kinds of acoustical alarms depending on the cause of 

possible inverter shutdown. These alarms are related to the red LED blinking  

sequences mentioned in chapter 1. The following acoustical alarms are available :

Alarm 1

One beep per second

. The battery voltage has reached a too low or too high 

level. If the battery voltage respectively decreases or increases any further, the 

inverter shuts down.

:

Alarm 2

Two beeps per second

. The inverter will shut down soon due to an 

overloaded output. Note that at heavy overloads the alarm will not sound due 

to too fast inverter shut down.

:

Alarm 3

Three beeps per second

. The inverter will shut down when it's  

temperature is rising another three degrees Celsius. 

:

5. Alarm relay

This inverter is equipped with a potential free alarm relay. This relay will be activated when 

the inverter shuts down and jumps to an error mode as described in chapter 1. The alarm 

relay de-activates again when the error mode has been cleared and the inverter is running 

in normal operating mode again. Both normally closed and normally open contacts of the 

alarm relay are available. The maximum relay contact ratings are 30Vdc/16A or 

230Vac/16A.

2. Inverter load requirements

Before you connect your appliance(s) to the inverter, always check it's maximum power 

consumption. Do not connect appliances to the inverter needing more than the nominal 

power rating of the inverter continuously. Some appliances like motors or pumps, draw 

large inrush currents in a startup situation. In these conditions, it is possible that the 

startup current exceeds the overcurrent trip level of the inverter. In this case the output 

voltage will shortly decrease to limit the output current of the inverter. If this overcurrent trip 

level is continuously exceeded, the inverter will shut down and restart within 20 seconds. 

In this case it is advisable to disconnect this appliance from the inverter, since it requires to 

much power to be driven by this inverter. The inverter will not restart automatically when it 

has shut down due to overloads for four times in a row. In this case, the inverter needs to 

be restarted manually. Note that at higher ambient temperature levels, the overload 

capacity of the inverter reduces.

7. Troubleshooting guideline

Problem

Possible cause

Remedy

Inverter is not working (all 

indicators are off).

Power switch in OFF (0) 

position.

Push the power switch in the 

ON (I) or ASB (II) position. 

Poor contact between the 

inverter's battery wires and 

the battery terminals. 

Clean battery terminals or 

inverter wire contacts. 

Tighten battery terminal 

screws.

Blown 

 fuse.

battery

Check and replace the 

battery fuse. 

Very poor battery condition. Replace battery.

'Battery voltage too low or 

too high' error keeps on 

appearing.

Poor battery condition.

Replace battery or charge it 

first.

Poor connection or 

inadequate wiring between 

battery and inverter, 

resulting in too much 

voltage drop.

Check battery wire 

connections. 

Decrease battery cable 

length. Increase battery and/

or cable size.

General failure in your 

electrical system (in case of 

no direct battery 

connection).

Check your electrical system 

or consult an electrical 

engineer to check it for you.

Too high ripple voltage on 

DC input.

Check battery wire 

connections. Decrease 

battery wire length. Increase 

battery size. Make sure that 

no other equipment on the 

same battery is generating a 

high ripple voltage.

'Output overload or short 

circuit' error keeps on 

appearing.

Inverter is overloaded.

Make sure that the total 

power rating of the 

connected equipment is 

lower than the nominal 

inverter power rating.

Connected equipment 

causes a short circuit at the 

inverter's output.

Make sure that the 

connected equipment is not 

broken or malfunctioning. 

Check if the AC power cord 

between the inverter and the 

connected equipment is ok. 

Any physical damage on the 

power cord can produce a 

short circuit.

Connected equipment 

causes a too large inrush 

current.

Try to power-up connected 

equipment successively, and 

not simultaneously. 

Otherwise stop using the 

connected load, it's not 

suitable to power it with this 

inverter.

‘High temperature error’ 

keeps on appearing.

Airflow around the inverter 

is obstructed.

Make sure there is at least 

10 centimeters of clearance 

around the inverter. Remove 

any items placed on or over 

the inverter. Keep the 

inverter away from direct 

sunlight or heat producing 

equipment.

Too high ambient 

temperature.

Move the inverter to a cooler 

environment or provide 

additional cooling by an 

external fan.

Note : Do not turn off the 

inverter when it's operating 

in an ‘High temperature 

error’. The inverter needs 

this error time to cool down.

6. Trigger input

The trigger input offers a way of externally controlling the behaviour of the inverter. The 

trigger input can be connected to an external switch or a potential free relay contact. By 

closing this external switch or contact, a user programmable 'action' will be performed. 

Such an action could for example be, to control an external fan when the output power has 

exceeded a certain level. All this can be configured in SAMLEX Dashboard (included in  

optional SAMLEXLink to USB Communication kit, art#64660). This inverter is equipped with

two trigger inputs.
