1. Important Safety Instructions
1-1. General Safety Precautions
1-1-1. Do not expose the inverter to rain, snow, spray or dust.
To reduce the risk of fire hazard, do not cover or obstruct the
ventilation openings and. do not install the inverter in a zero-
clearance compartment.
1-1-2. To avoid the risk of fire and electric shock, make sure that the
existing
wiring is in good electrical condition; and that the wire size is not
undersized.
Do not operate the inverter with damaged or substandard wiring.
1-1-3. Depending on the use, the AC output of the inverter may require
user installed breaker or fusing. For telecom use, a GFCI has not
been provided. The inverter incorporates standard AC short circuit
protection.
1-1-4. The following precautions should be taken when working on the
inverter:
▌Remove watches, rings, or other metal objects.
▌Use tools with insulated handles.
▌Wear rubber gloves and boots.
1-2. Other Safety Notes
1-2-1. Upon receipt, examine the shipment box for damage. Notify the
carrier immediately, before opening, if damage is evident.
1-2-2. Do not operate near water or in excessive humidity.
1-2-3. Do not open or disassemble the inverter, warranty may be voided.
1-2-4. The DC side connections should be firm and tight.
1-2-5. Grounding: Reliable grounding of rack-mounted equipment should
be maintained.
1-2-6. Do not drop a metal tool on the battery. The resulting spark or short-
circuit on the battery or on the other electrical part may cause an
explosion.
WARNING!
SAVE THESE INSTRUCTIONS – This manual contains
important instructions that should be followed during
installation and maintenance of the inverter.

1-2-7. Install the inverter in a well-ventilated area. Do not block the front
air vents, or the rear air exhausts of the unit.
1-2-8. Wiring: Adequate input power must be supplied to the inverter for
proper use; correct wiring sizes must be ensured.
1-2-9. Mount the inverter such that the fan axis is horizontal.
1-2-10. Do not operate the inverter close to combustible gas or open fire.
1-2-11. Do not operate appliances that may feed power back into the
inverter.
1-2-12. Temperature: The inverter should be operated in an ambient
temperature range of 0℃to 50 ℃or else the output efficiency
may be affected. Air flow to the inverter must not be restricted.
2. Functional Characteristics Introduction
2-1. System
The unit is a highly reliable DC-AC inverter system, designed with advanced
power electronic and microprocessor technology offering the following features:
▌The inverter is equipped with a self diagnosis microprocessor that is able
to identify and show all failure messages on the LED/LCD display,
with associated visual/audio alarms.
ĭ
1U height x 19” width x 13.6” depth, 19” rack mountable.
▌Pure sine wave output (THD < 2%) to operate higher-end electronic
equipment.
▌Built in 12A rated transfer switch.
▌Speeds up transfer time as a result of synchronized operation with the
AC source at all times that allows the transfer to be interruption-free for
sensitive equipment.
▌Intelligent software for power management.

The inverter features IGBT technology which, minimizes weight and dimension,
while enhancing output short circuit reliability and overload capacity.
AC output voltage is provided in one of the two following modes:
1). From DC to AC Inverter Mode: (On-line Mode)
2). From AC Input Bypass Mode: (Off-line Mode)
Either mode is front panel programmable.
In the first option, Off-line mode, AC output power will be supplied through the AC
bypass mode in its normal operation. Upon AC input failure, output power will be
diverted through the DC to AC Inverter Mode. Once AC mains are restored, the unit
will revert from the Inverter Mode to the Bypass Mode.
In the second option, On-line mode, AC output power will be provided directly by
the inverter from the DC source. Should the DC source or inverter fail, the system
will transfer its output power through the bypass mode. Once the DC power source
is restored, the system will revert to the inverter mode.

Note: The specifications are subject to change without 5
notice.

3-1-1. AC Input Breaker:
The AC input circuit breaker protects the unit from overload. When an overload
condition occurs, the circuit breaker trips and disconnects the AC grid power
input. To reset it, push the circuit breaker button. The cause of tripping should
be ascertained and corrected before the unit is reset .

3-1-7.DC Input Connection:
Follow the instructions to connect the battery cables to the DC input
terminals of the inverter. The cables should be as short as possible (less
than 6 feet / 1.8 meters ideally) so that they can handle the required
current in accordance with the Electrical Codes and Regulations. The size
of the cable should be thick enough to limit the voltage drop to less than
2% when carrying the maximum input current to prevent frequent low-input
voltage warnings, and shutdown. UVP (Under Voltage Protection) warning
may result if there is excessive voltage drop across the DC cables between
the batteries and the inverter.
Increasing your DC cable size will help improve the situation.
Batteries are capable of providing very large currents in case of short
circuit. In case there is a short circuit in the cable run between the batteries
and the input terminals of the inverter, it will result in overheating / melting
of the cables and consequent risk of fire and injury, To prevent possibility of
this hazard, use Very Fast Acting DC Fuse in line with the positive cable.
The fuse should be as close to the positive battery terminal as possible.
Use Bussmann ANN series fuses ( will also require Fuse Block 4164) or
equivalent.
The following sizes of cables and fuses are recommended for up to 6 ft.
distance between the batteries and the inverter. (Applies to both 120 VAC
and 230 VAC versions):
Model No Wire AWG Inline Fuse
AMV OND1000-24-C1 # 4 80A

▌Connect DC input terminals to 24V / 48V battery or other DC power source.
[ + ] is positive, [ - ] is negative. Reverse polarity connection can blow the
internal fuse and may damage the inverter permanently.
WARNING!
Make sure that all the DC connections are tight (torque
to 9 – 10 ft-lbs, 11.7 – 13 Nm). Loose connections
could result in overheating and can be a potential
hazard.

operate normally. When the “Frequency” is less than
43 Hz or more than 58 Hz, the internal transfer relay
will de-energize (See details in Section 2-2)
Default= 0.1Hz ~ 7Hz.
Model SETTING VALUE RANGE
110 V 0.1 Hz ~ 7 Hz
