AIMS Power www.aimscorp.net 1. Important Safety Information WARNING! Before using the Inverter, you need to read and save the safety instructions. 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 30CM of clearance around the inverter for air flow.
AIMS Power www.aimscorp.net 2. Introduction 2-1. General Information Global LF Series Pure Sine Wave Inverter is a combination of an inverter, battery charger and AC auto-transfer switch into one complete system with a peak conversion efficiency of 88%. It is packed with unique features and it is one of the most advanced inverter/chargers in the market today.

AIMS Power www.aimscorp.net For 12VDC models: after the battery voltage goes below 10V and the power switch is kept in the "ON" position and the inverter stays connected to the battery and the battery voltage doesn’t drop below 2V, the inverter will be able to charge the battery once qualified AC inputs are present. Before the battery voltage goes below 9VDC, the charging can be activated when the switch is turned to “Off”, then to “ON”.
AIMS Power www.aimscorp.net All our Global LF line of inverters have a 50/60 hz selector switch. When the inverter is turned off and shore power is not present, the frequency of the inverter may be selected to be 50 or 60 hz. 2.5.5 Power Saver There are 2 different working statuses for our Global LF inverter: “Power On” and “Power Off”. When the power switch is in “Unit Off” position, the inverter is powered off.

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 Apart from the switch panel on the front (or top) of the inverter, an extra switch panel connected to the RJ11 port at the DC side of the inverter thru a standard telephone cable can also control the operation of the inverter (sold separately Part # PICGLFREMOTE). If an extra switch panel is connected to the inverter via “remote control port”, together with the panel on the inverter case, the two panels will be connected and operated in parallel.

AIMS Power SW4 SW5 www.aimscorp.net ON/OFF Frequency Switch Battery/AC Priority 50Hz AC Priority 60Hz Battery Priority Low Battery Trip Point(SW1): Deep discharge of the lead acid battery leads to high losses in capacity and early aging. In different applications a different low voltage disconnection level is preferred. For example, for solar applications, user may intend to have less DOD to prolong the battery life cycle.
AIMS Power www.aimscorp.net The output frequency of the inverter can be set at either 50Hz or 60Hz by SW4. AC/Battery Priority(SW5): Our inverter is designed with AC priority by default. This means, when AC input is present, the battery will be charged first, and the inverter will transfer the input AC to power the load. Only when the AC input is stable for a continuous period of 15 days will the inverter start a battery inverting cycle to protect the battery.
AIMS Power www.aimscorp.net Battery voltage recovery start After low battery voltage shut off (10V for 12V model or 20V for 24V model or 40V for 48V model), the inverter is able to restore operation after the battery voltage recovers to 13V/26V/52V (with power switch still in the “On” position). This function helps to save the users extra labor to reactivate the inverter when the low battery voltage returns to an acceptable range in renewable energy systems.

AIMS Power Back Feed Short www.aimscorp.net × × Symptom Inverter will not turn on during initial power up. × × × × Possible Cause Batteries are not connected, loose battery-side connections. × × × × Beep continuous Recommended Solution Check the batteries and cable connections. Check DC fuse and breaker. Low battery voltage. No AC output voltage and no indicator lights ON. AC output voltage is low and the inverter turns loads OFF in a short time.
AIMS Power www.aimscorp.net 5 Warranty We offer a 1 year limited warranty. The following cases are not covered under warranty. 1 DC polarity reverse. The inverter is designed without DC polarity reverse protection.
