INSPECTION

The package contents:

(1)MINUTEMAN PowerCenter software (floppy disk); (1) Serial interface cable (DB-9); (1) Telephone cable; (1) User’s Manual; (1) Warranty registration card; (1) Platinum Protection Policy; (1) UPS.

HOW TO DETERMINE THE POWER REQUIREMENTS OF YOUR EQUIPMENT

1.Make sure that the total Volt-Amp (VA) requirements of your computer, monitor and peripheral equipment does not exceed 1200VA for the MN 325 or 1440VA for the MN 525.

2.Ensure that the equipment plugged into the battery-powered outlets does not exceed the UPS’s rated capacity. If UPS’s rated capacities are exceeded, an overload condition may occur and cause the UPS to shut down and trip the circuit breaker.

3.If the power requirements of your equipment are listed in values other than Volt-Amps (VA), convert Watts (W) or Amps (A) into VA by doing the calculations below. Note: The equation be- low only calculates the maximum amount of VA that the equipment can use, not what is typically used by the equipment at any given time. Users should expect usage requirements to be ap-

proximately 60% of below value to estimate power requirements:

Watts (W) x 1.82 = VA or Amps (A) x 120 = VA

Add the totals for all of the equipment and multiply this total by 0.6 to calculate actual require- ments.

Note: Many factors can affect the amount of power that your computer system will require. The total load that you will be placing on the battery-powered outlets should not exceed 80% of the UPS’s capacity.

Hardware Installation Guide

1.Your new UPS may be used immediately upon receipt. However, charging the battery for at least 4-hoursis recommended to ensure that the battery’s maximum charge capacity is achieved. Charge loss may occur during ship- ping and storage. To recharge the battery, plug the power cord into the AC wall outlet and turn the power switch on. Note: The MN 525 will charge the battery with the power switch on or off.

2.If you wish to use the software, connect the en- closed serial interface cable to the serial port on the UPS and an open serial port on the computer. If you are not going to use the software, you do not need to connect the cable.

3.With the UPS unit off and unplugged, connect your

computer, monitor, and any externally powered data storage device (Zip drive, Jazz drive, Tape drive, etc…) into the battery power sup- plied outlets. Plug your peripheral equipment (printer, scanner, speakers) into the full-time surge protection outlets. DO NOT plug a laser printer, copier, space heater, vacuum or other large elec- trical device into the UPS. The power demands of these de- vices will overload and possibly damage the UPS.

4.To protect a fax, phone or modem, connect a telephone cable from the wall jack outlet to the IN jack of the UPS. Connect a telephone cable from the OUT jack to the modem port on your computer. The OUT jack can be used to protect a telephone or fax machine.
