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 SafetyNotes

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.

▌ 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 15A(120VAC) and 10A(250VAC) rated Bypass relay.

▌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.

▌AC Inlet and Dual AC outlets connection model option.

▌Loading and temperature controlled cooling fan.

▌Fan aging, failure, disconnection and blockage alarm.

▌Selectable Bypass/Inverter modes.

▌Local and remote management and control.

SR Series Inverter

▌RS-232 communication.

▌Dry contact terminal.

▌Efficiency >90%. (Full linear load at 220VAC Output)

▌ Advanced Protection Features:

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.

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 .
