Minuteman Continuous Power Series UPS

HOW THE CONTINUOUS POWER SERIES PROTECTS YOUR SYSTEM

The Continuous Power Series UPS has two basic functions:

 Prevent AC line interruptions from disrupting your load (computer

network, workstations, etc.)

 Condition poor quality AC power before it disrupts your load

AC power disturbances come in many forms, from full blackouts to radio

transmissions on a factory floor. The Continuous Power Series is designed to

respond to these power problems before they affect the operation of your

sensitive electrical equipment. Various types of AC power disturbances in-

clude:

 No voltage (blackout)

 Low voltage (brownout)

 High voltage

 Slow voltage fluctuation (voltage sag)

 Frequency variations

 Common mode noise

 Normal mode noise

 Transients caused by switching and faults

Electrical disturbances can damage software, hardware, and cause equipment

to operate erratically. The Continuous Power Series protects equipment by

maintaining a constant output voltage and by conditioning poor quality AC

power before it reaches sensitive electric equipment. Because the Continuous

Power Series is a true online UPS, it also provides instantaneous backup

power during a power failure with no interruption to your load(s). The block

diagram in Figure 1-2 illustrates how the Continuous Power Series UPS is

connected to AC power and loads.

TOWER

 Avoid temperature and humidity extremes. To maximize the lifetime of

the batteries, an ambient temperature of 59°F to 77°F (15°C to 25°C) is

recommended.

 Provide shelter from the elements (especially moisture).

 make sure ventilation and space requirements are met. There should

be two inches (5 cm) of clearance at both sides and on top of the UPS.

Four inches (10 cm) of clearance is needed at the rear of the UPS for

ventilation.

 Maintain clearance at the front of the UPS for user operations.

 Install the external battery pack next to the UPS.

RACK-MOUNT

 The rack-mount UPS fits into a standard equipment rack (mounting

hardware is not provided).

 To maximize the life of the UPS internal batteries, avoid temperature

and humidity extremes.

 The ambient temperature should be kept around 59°F to 77°F

(15°C to 25°C).

ATTACHING THE STABILIZING BRACKET

6.0 KVA units come with a stabilizing bracket used to secure the unit once it is

placed. Follow the instructions below to attach the stabilizing bracket.
