AIMS Power www.aimscorp.net 1. Important Safety Information Save This Manual! Read this manual before installation, it contains important safety, installation and operating instructions. Keep it in a safe place for future reference. All wiring must follow the National Electric Code, Provincial or other codes in effect at the time of installation, regardless of suggestions in this manual. All wires should be copper conductors. 1.1 General Safety Precautions 1.1.

AIMS Power www.aimscorp.net 2.5 Electrical Performance 2.5.1 Invert Topology The Global LF inverter/charger is built according to the following topology. Invert: Full Bridge Topology. Charge: Isolated Boost Topology. It works bi-directionally: in one direction it converts DC power from the battery to AC power (Inverter Mode) and in the other direction it converts external AC power to DC power to charge the batteries (AC Mode).
AIMS Power www.aimscorp.net switching on the inverter with the load already switched on. This may prematurely trigger the overload protection. When a load is switched on, it may require initial higher power surge to start. Hence, if multiple loads are being powered, they should be switched on one by one so that the inverter is not overloaded by the higher starting surge if all the loads are switched on at once. 2.5.
AIMS Power www.aimscorp.net Figure 5 De-sulphation The de-sulphation cycle, switch position 8, is marked in red because this 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 so low that they will not accept a charge.
AIMS Power www.aimscorp.net Before the battery voltage goes below 9VDC, the charging can be activated when the switch is turned to “Off”, then to “ON”. When the voltage goes below 9VDC, and you accidently turn the switch to OFF or disconnect the inverter from the battery, the inverter will not be able to charge the battery once again, because the CPU loses memory during this process.

Transfer Delay There is a 15-second delay from the time the inverter senses that continuously qualified AC is present at the input terminals to when the transfer is made. This delay is built in to provide sufficient time for a generator to spin-up to a stable voltage and frequency and avoid relay chattering.

At full output voltage, the green power LED will light steadily and the inverter will make a steady humming sound.
AIMS Power www.aimscorp.net 2.5.6 Remote Control Apart from the switch panel on the front (or top) side of the inverter, an extra LCD remote switch panel (Figure 11, sold separately Part #: REMOTELF) connected to the remote port at the DC side of the inverter through a standard Ethernet cable can also control the operation of the inverter.
AIMS Power www.aimscorp.net 2.5.7 LED Indicator The operation status of the inverter is shown by the LED’s and the explanation on the LED sticker (Figure 12). Figure 12 2.5.8 Audible Alarm The inverter also gives audible alarms when the following situations occur. Battery Voltage Low Inverter green LED lit, and the buzzer beeps 0.5s every 5s. Inverter green LED lit, and the buzzer beeps 0.5s every 1s and Fault after Battery Voltage High 60s.
AIMS Power www.aimscorp.net 2.5.9 FAN Operation For 1-3KW models, there is one multiple controlled DC fan which starts to work according to the below logic.
AIMS Power www.aimscorp.net While for some resistive loads which work in a wide voltage range, the input AC range can be customized to 90-135V, this helps to power loads with the most AC input power without frequent switches to the battery bank. In order to make the inverter accept dirty power from a generator, when the SW2 is switched to position “1”, the inverter will bypass an AC input with a wider voltage and frequency (40Hz plus for 50Hz/60Hz).
AIMS Power www.aimscorp.net 2.5.11 Auto Generator Start The inverter can start up generator when battery voltage goes low. When the inverter goes to low battery alarm, it can send a signal to start a generator and turn the generator off after battery charging is finished. The auto gen start feature will only work with generators which have automatic starting capability. The generator must have start and stop controls [i.e.
AIMS Power www.aimscorp.net Important: If the battery temperature is allowed to fall to extremely cold temperatures, the inverter with a BTS may not be able to properly recharge cold batteries due to maximum voltage limits of the inverter. Ensure the batteries are protected from extreme temperatures. For more detailed technical information, please contact us. 2.5.
AIMS Power www.aimscorp.net Relative Humidity: 0% to 95%，non-condensing Cooling: Forced air CAUTION: Some models of the inverters are heavy. Use proper lifting techniques during installation to prevent personal injury. WARNING! The inverter should not be installed in an area that allows dust, fumes, insects or rodents to enter or block the inverter’s ventilation openings. This area also must be free from any risk of condensation, water or any other liquid that can enter or fall on the inverter.
AIMS Power www.aimscorp.net Please follow the above minimum wire size requirement. Power One cable is always best, but if there is a problem obtaining the recommended size or larger cable, multiple smaller cables will work. Performance of any product can be improved by thicker cable and shorter runs, so if in doubt round up and keep the length as short as possible. 1KW 1.
AIMS Power www.aimscorp.net The inverter contains capacitors that may produce a spark when first connected to battery. Do not mount in a confined compartment with vented battery or gases. Ensure the inverter is off before disconnecting the battery cables, and that AC power is disconnected from the inverter input. 3.4 AC Wiring The AC terminal is rated for wires of AWG 8 to AWG20, we recommend using 10 to 8Awg wire to connect to the ac terminal block.
AIMS Power www.aimscorp.net 3.5 Grounding 3.5.1 Grounding the Inverter Chassis Connect an AWG 8 gauge or greater copper wire between the grounding terminal on the inverter and the earth grounding system or the vehicle chassis. 3.5.2 Automatic Neutral-to-Ground Connection All single phase 120Vac inverters are equipped with automatic neutral-to-ground switching.
AIMS Power www.aimscorp.net 3.6 Mounting the Inverter In order to mount the inverter securely, the surface and the mounting hardware must also be able to support at least twice the weight of the inverter. To meet regulatory safety requirements, the PICOGLF Series must be mounted: Figure 23 Figure 22 2: On a vertical surface (like a wall) with the DC 1: On a horizontal surface (shelf or table top) with terminals facing left and the fan axis horizontal. top side up, Figure 25 4 On a surface upside down.
