Dear Customer, Thank you for purchasing the ZEB-MLS750 UPS. Please read the user manual carefully before usage & save it for future reference.

Important Safety Instructions

The voltages inside UPS may be hazardous. Do not attempt to disassemble the unit. The unit contains no user-serviceable parts. Only factory service personnel may perform repairs.
Internal battery voltage is 12Vdc. sealed, lead-acid, 6 cells battery.
Connection to any other type of socket other than a two-pole, three-wire grounded socket may result in shock hazards as well as violating local electrical codes.
In the event of an emergency, press the OFF button and disconnect the power cord from the AC power supply to properly disable the UPS. Do not allow liquids or any external objects to enter the UPS. Do not place beverages or any other liquid-containing vessels on or near the unit.
This unit is designed for installation in a controlled environment (temperature controlled, indoor area free of conductive contaminants). Avoid installing the UPS in locations where there is static or flowing water or excessive humidity.
Do not plug the UPS input into its own output.
Do not attach a power strip or surge Suppressor to the UPS.
Do not connect non-computer-related items, such as medical equipment, _life-support equipment, microwave ovens, or vacuum cleaners to UPS.
To reduce the risk of overheating the UPS, do not cover the UPS cooling vents and avoid exposing the unit to direct sunlight or installing the unit near heat-emitting appliances such as air heaters or furnaces.
Unplug the UPS prior to cleaning and do not use liquid or spray detergent.
Do not dispose the batteries into fire as they may explode. Do not open or mutilate the battery or batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic.
A battery can present a risk of electrical shock and a high short circuit current. The following precautions should be observed when working on batteries:
a) Remove watches, rings, or other metal objects from the hands.
b) Use tools with insulated handles.
c) Wear rubber gloves and boots.
d) Do not lay tools or metal parts on top of batteries.
Disconnect the charging source prior to connecting or disconnecting battery terminals.
Servicing of battery should be performed or supervised by technical and authorized personnel only.
When replacing the battery, replace it with the same type of sealed lead-acid battery. The maximum ambient temperature rating is 40°C.

UPS Installation Procedure

Your new UPS may be used immediately; however, recharging the battery for at least 8 hours (no load) is recommended to ensure that the battery’s maximum charge capacity is achieved. Charge loss may occur during shipping and storage. To recharge the battery, simply leave the unit plugged into an AC outlet. The unit will charge in both the on and off position.
With the UPS unit off and unplugged, connect the computer, monitor, and any externally powered data storage device (Zip drive, Jazz drive, Tape drive, etc.) into the battery power supplied outlets. DO NOT plug laser printer, copier, space heater, vacuum, paper shredder, or another large electrical device into the battery power supplied outlets. The power demands of these devices will overload and possibly damage the unit.
Plug the UPS into a 2 pole, 3 wire grounded socket (wall outlet). Make sure the wall branch outlet is protected by a fuse or circuit breaker and does not. service equipment with large electrical demands (e.g. air conditioner, refrigerator. copier, etc. Avoid using extension cords.
Press the power switch to turn the unit ON. The power on_ the indicator light will illuminate and the unit will “beep”.
If an overload is detected, an audible alarm will sound and the unit will emit a beep once every 0.5 seconds. To correct this turn the UPS off and unplug at least one piece of equipment from the battery power supplied outlets. Wait 10 seconds and then turn the UPS on.
To maintain optimal battery charge, leave the UPS plugged into an AC outlet at all times.
To store your UPS for an extended period, cover it and store it with the battery fully charged. Recharge the battery every three months to ensure battery life.
