■ Transfer switch system / LED display
Transfer switch system
This product was developed using digital circuit design based on a patented technology DSP (digital signal processor), and is a very
reliable, high performance, light weight inverter.
● 120Vac is either supplied by city power(by pass mode) or inverter(DC or backup mode). A program will control this automatically or it
may be manually controlled(by city power circuit breaker)
● By pass mode
Standard operation is for the city power to provide ac out
Upon AC city power mode failure, output is converted to inverter mode through DC conversion.
If AC city power is restored, unit will revert back to bypass mode (city power) automatically by the transfer switch program.
● DC or backup mode.
In DC mode (city power circuit breaker OFF) the inverter will supply ac out power as long as the dc supply provides enough voltage to
inverter.

A. Verify the battery operating voltage and protection switch is on (inverter off).
B. Tum protection switch "off "(circuit breaker) once the battery connection has been verified.
C. The length of the cable may vary slightly, but should preferably be less than 10 Ft. The shorter the lenght of the cable the better the
batteries will perform.
If a longer distance is needed, a larger gauge cable is required.
minimum cable size recommendations : 12Vdc / 4Awg, 24Vdc / 6Awg, 48Vdc / 8Awg
D. Connect the Red cable lug to the positive on the battery and Black lug to the negative of the battery.
Arrange the battery cables to the safest angles. Turn inverter on and confirm inverter is operating properly.
E. Turn protection switch "off " If the buzzer is sounding, turn the connected AC devices off and toggle the power switch off then on.
The buzzer should stop.
F. Now you should connect and turn the AC devices on. Most equipment using motors, have a higher startup requirement.
This may cause the inverter to buzz and go into overload or pop the circuit breakers. This should not damage the inverter;
however you should not continue to try and power up the equipment. Repeated overloads will cause damage to the inverter Call
AlMS Power Tech support and verify startup requirements.
G. The frequency of the inverter is fine-tuned at 60Hz from the manufacture.
H. The inverter may operate in overload for a short period of time. If you continue the use in overload, the inverter may overheat and
shut down. You will then be required to turn the inverter off and on again.

than the listed running requirements at 3 to 5 times the continuous current rating.
To keep the life expectancy of the inverter at its maximum, please ensure plenty of ventilation. Keep dust and foreigh debris out of inverter.
Troubleshooting

14
■ General problems
Audio system noise :Noise may be generated from speakers or amplifier when using the inverter to power low-grade stereo
systems and large portable radios. This is due to the interference between the electricity and current
running through each device. You are hearing the RF generated by the inverter.
TV interference :The operation of this inverter may cause interference in receiving specific TV channels; in this case
perform the following procedure’s to try to resolve the problems.
Audio, TV and wireless devices shall be installed in an area as far as possible away from the inverter. Try installing a line filter
on affected device.
General problems:
• For normal operation, devices with excessive loads applied momentarily such as refrigerators , air conditioners, electric motors,
hand tools Etc. Should be within 60% of the maximum output capacity of this inverter. Check the capacity of this inverter as well
as the capacity of the intended devices to be used.
• When the rated continuous capacity of the motor is equal to or greater than the rated capacity of the inverter, operation of the
intended device may not be available due to the inverters lack of surge ability.
• Devices using heaters will increase the temperature of the inverter drastically. When using devices like this make sure to provide
proper ventilation for the inverter. Improper ventilation will cause inverter shutdown and malfunction resulting in irreversible
damage.
• Audio and video devices shall be used within the maximum power rating of the inverter. If the rating capacity is exceeded there
will be a momentaty cut-off. For safe operation use 75%-80% of the listed capacity.
