Installation

Inspection: Upon receiving the UPS, inspect it. The packaging is recyclable. Save it for reuse or dispose properly.
Placement: To prevent the risk of fire or electronic shock, install the UPS in a temperature and humidity controlled ventilated enclosure, free of conductive contaminants, moisture, flammable, gases, and corrosive substances.
To reduce the risk of electronic shock, do not remove cover, it has no user- serviceable parts Hazardous live parts inside this unit are energized from the battery supply even when the input AC power is disconnected
Utility power: The terminal block is used to “hardwire” the UPS, thus allowing connection of input/output wiring. Use AWG wire as stated in the table. Input / Output wires should be secured with terminal block screws using 9 lb.-in. of torque. The input utility power should match with the UPS. (For example, the voltage rating of UPS is 120V/(220V), input utility should also be 120/(220)).
Connection:

Connect the AC Input power conductors (L, N, and G) to the UPS Input Terminal Blocks (L, N, and G) respectively.
Connect the Output Power Conductors (L, N, and G) from the UPS Output Terminal Blocks to the load equipment (L, N, and G) respectively.
The UPS Input and Output Terminal Blocks can accept conductor sizes ranging from 10AWG to 18AWG.

Operation

Output Connector: The output connector will provide protection from surges and power failures to the critical loads.
Switch ON: After connecting the UPS to the utility power, press the ON button until the first beep stops, then release the button immediately.
Switch OFF: To switch OFF the UPS, press and hold the ON/OFF button until the “AC MODE” LED or “BATTERY MODE” LED turns OFF.
Remote ON/OFF: To ensure the Remote ON/OFF function, connect a Remote push- button switch in series with 5-30V DC voltage source to the ON/OFF terminal. The remote switch provides the same functions as the front panel switch including ON/OFF/TEST/SILENCE functions.

Alarm

“BACKUP” (slow alarm): When the UPS is working in the “BACKUP” mode, there would be an audible alarm. When the UPS returns to “LINE” mode operation, the alarm would stop.
Attention: In the “BACKUP” mode, the alarm will beep every 2 seconds. (Slow- speed beep). Attention: The UPS provides mute function for this warning. When the beeping sound occurs, press “ON” to stop it; and press “ON” again to resume the sound.
“LOW BATTERY”(rapid alarm): When the UPS is working in the “BACKUP” mode, with energy of the battery between 20%~30% (low level), the UPS will beep rapidly until the UPS shuts down from battery exhaustion or returns to “LINE” mode operation.
Attention: The alarm due to low voltage of the batteries beeps every 0.5 second. Attention: The rapid alarm under “LOW BATTERY” condition cannot be muted.
“OVER LOAD” (continuous alarm): When the UPS is working under overload condition (the connected loads exceed the maximum rated capacity), the UPS will emit continuous alarm to warn an overload condition. In order to protect the unit and the loads, the UPS will be automatically turn Off. Please disconnect nonessential devices from UPS to eliminate the overload alarm.

Software (Optional)

Power Monitoring Software
The UPS-MON software (or other power monitoring software) is applied via standard
RS-232 interface to perform monitoring functions. The cable must be connected from the UPS end to a REMOTE PORT on the computer end. It can be either be COM 1 or COM 2. It provides an orderly shutdown of a computer in the event of a power failure. Moreover, UPS-MON displays all the diagnostic symptoms on the monitor, such as Voltage, Frequency, Battery level and so on. The software is available for Windows XP, 7,8, 10, Server-2000, 2003, 2008, 2012 and Linux. Call Marathon Power technical support for assistance on OS.

Interface Kits
A series of interface kits are available for operation systems (Such as PLC, SCADA, signal controllers, etc.) that provide UPS monitoring. Each interface kit includes a special interface cable required to convert status signals from the UPS into signals which the individual system recognizes. The interface cable from the UPS end must be connected to a REMOTE PORT on the computer end. It can be either be COM 1 or COM 2. For other installation instructions and powerful features please refer to READ.ME file.
Attention: Use only the cable supplied by factory or authorized UPS monitoring cable!

The characteristics of computer interface port
The computer interface port has the following characteristics:

The communication port located on the bottom of the UPS may be connected to a host computer. This port allows the computer to monitor the status of the UPS and control its operations in some cases. Its major functions normally include some or all of the following:
- To broadcast a warning when power fails.
- To close any open file before the battery is depleted.
- To turn-off the UPS.
Some computers are equipped with a special connector to link with the communication port. In addition, a special plug-in cord may be needed. Some computers may need special UPS monitoring software. Contact Marathon Power for details on the various interface Kits.
