1. Important Safety Information NOTE: Before using the inverter, read and save this manual. 1‐1. General Safety Precautions 1-1-1. Do not expose the inverter to rain, snow, spray, bilge or dust. To reduce risk of hazard, do not cover or obstruct the ventilation openings. Do not install the inverter in a zero-clearance compartment. Overheating may result. Allow at least 12” of clearance around the inverter for air flow. Make sure that the air can circulate freely around the unit.

Overload Capacity: The Global LF series inverters have high overload capacities, making it ideal to handle demanding loads. 1. For 110%150%(±10%), beeps 0.5s every 1s and Fault (Turn off) after 20s.
(determined by the Battery Type selection*). In this stage, the batteries are kept fully charged and ready if needed by the inverter. If the AC is reconnected or the battery voltage drops below 12Vdc/24Vdc, the charger will restart the above cycle. If the charge maintains the float state for 10 days, the charger will deliberately reset the cycle to protect the battery.

De-sulphation The de-sulphation cycle (switch position 8) is a very dangerous setting if you do not know what you are doing. Before attempting to use this cycle, you must clearly understand what it does and when and how you would use it. What causes sulphation? This can occur with infrequent use of the batteries or if the batteries have been discharged low enough that they will not accept a charge.
switch delay our inverter gives the generator enough time to spin up. This will depend on the size of the generator and rate of charge. Generally, the Bulk Charging Current should be limited to 20% of the capacity of the battery bank. Higher charging current may be used if permitted by the battery manufacturer. Warning: Items of note not covered under warranty. To set the charge current control switch, use a small jeweler’s style flat-head screwdriver and gently turn to avoid breakage due to over‐turning.
When the power switch is turned to either “Power Save ON” or “Power ON”, the inverter is powered on. The Power Saver function is designed to conserve battery power when AC power is not or rarely required by the loads. In this mode, the inverter pulses the AC output looking for an AC load (IE. electrical device). Whenever an AC load (greater than 50-100 watts depending on model) is turned on, the inverter recognizes the need for power and automatically starts inverting and output goes to full voltage.

The low battery voltage trip point can be customized from a defaulted value of 10VDC to 10.5VDC thru SW1 on the DIP switch. The inverter will go to over temp protection when the heat sink temp. ≥105ºC(221℉), and go to fault ( shutdown Output) after 30 seconds. The switch needs be reset to activate the inverter. The Global LF series inverter has back feeding protection which avoids presenting an AC voltage on the AC input terminal in inverter mode.

In order to make the inverter accept dirty power from a generator, put SW2 to position “1”, the inverter will bypass an AC input with a wider voltage and frequency (40-70Hz for 50Hz/60Hz). The AC charger will also work in a wider voltage and frequency range (42-68Hz for 50Hz/60Hz). As mentioned, this will avoid frequent switching between battery and generator, but the low-quality power may affect some sensitive loads. The pros and cons should be considered when dealing with sensitive loads.
2.5.13 Other Features Battery Temperature Sensing Applying the proper charge voltage is critical for achieving optimum battery performance and longevity. The ideal charge voltage required by batteries changes with battery temperature. The Battery Temperature Sensor allows the charger to continuously adjust charge voltage based on actual battery temperature. Temperature compensation of charge voltage assures that the battery receives the proper charge voltage as battery temperature varies.

3-2. Location Follow all the local regulations to install the inverter. Install the equipment in an INDOOR location that is dry, clean, free from dust, cool and with good ventilation. Working temperature: -14℉ to 122℉ | Storage temperature: 40℉ to 158℉ | Relative Humidity: 0% to 95, non-condensing | Cooling: forced air Do not install upside down (top side facing down). CAUTION: Some models are heavy. Use proper lifting techniques during installation to prevent personal injury.
WARNING! The inverter charger must be connected to a battery bank in order to turn on and transfer AC power. Power 1KW 1KW 1.5KW 1.
Reducing RF interference To reduce the effect of radiated interference, twist the DC cables. To further reduce RF interference, shield the cables with sheathing /copper foil / braiding. Taping battery cables together to reduce inductance Do not keep the battery cables far apart. In case it is not convenient to twist the cables, keep them taped together to reduce their inductance. Reduced inductance of the battery cables helps to reduce induced voltages.
Do not loosen or touch the rear set screws on the terminal block.

That is a half wave load: A load that uses only half a cycle of the power. This tends to cause an imbalance of the magnetic field of the transformer, reducing its rated working frequency from 20KHz to, say, maybe 15KHz (it varies according to different loads). In such a case the frequency of noise falls exactly into the range (200Hz-20KHz) that human ears can hear. The most common load of such kind is a hair drier.
