Chapter 1 NCR 4072 – One of the Best!

The NCR 4072 uninterruptible power system (UPS) protects your
sensitive electronic equipment from basic power problems such as power
failures, power sags, power surges, brownouts, and line noise.

Power outages can occur when you least expect it and power quality can
be erratic. These power problems have the potential to corrupt critical
data, destroy unsaved work sessions, and damage hardware — causing
hours of lost productivity and expensive repairs.

With the NCR 4072 UPS, you can safely eliminate the effects of power
disturbances and guard the integrity of your equipment. The NCR 4072
UPS’s flexibility to handle an array of network devices makes it the
perfect choice to protect your LANs, servers, workstations, and other
electrical equipment.

Chapter 2 Safety Warnings

Read the following precautions before you install the UPS.

IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS

This manual contains important instructions that you should follow during
installation and maintenance of the UPS and batteries. Please read all
instructions before operating the equipment and save this manual for future
reference.

This UPS contains LETHAL VOLTAGES. All repairs and service should be
performed by AUTHORIZED SERVICE PERSONNEL ONLY.ThereareNO USER
SERVICEABLE PARTS inside the UPS.

쑺 This UPS contains its own energy source (batteries). The output receptacles

may carry live voltage even when the UPS is not connected to an AC supply.

쑺 For 220–240V models, t he output receptacles may remain electrically live. If

the input power source in your application is wired line-to-neutral (as in
most European applications), the voltage to the output receptacles is 0V.
With line-to-line input wiring, the voltage to the output receptacles is
110–120V (measured from line-to-ground or line-to-neutral, depending on
the UPS wiring).

쑺 Do not remove or unplug the input cord when the UPS is turned on. This

removes the safety ground from the UPS and the equipment connected to
the UPS.

쑺 To reduce the risk of fire or electric shock, install this UPS in a temperature

and humidity controlled, indoor environment, free of conductive
contaminants. Ambient temperature must not exceed 40°C (104°F). Do not
operate near water or excessive humidity (95% max).

쑺 To comply with international standards and wiring regulations, the total

equipment connected to the output of this UPS must not have an earth
leakage current greater than 1.5 milliamperes.

Safety Warnings

CAUTION

쑺 The wall outlet must be within 2 meters of the equipment and accessible to

the operator.

쑺 Batteries can present a risk of electrical shock or burn from high

short-circuit current. The following precautions should be observed:

1) Remove watches, rings, or other metal objects; 2) Use tools with insulated
handles; 3) Do not lay tools or metal parts on top of batteries; 4) Disconnect
charging source prior to connecting or disconnecting battery terminals.

쑺 Proper disposal of batteries is required. Refer to your local codes for

disposal requirements.

쑺 Never dispose of batteries in a fire. Batteries may explode when exposed to

flame.

쑺 Never open or mutilate batteries. Released electrolyte is harmful to the skin

and eyes, and may be extremely toxic.

쑺 Replace batteries with the same number and type of batteries as originally

installed in the UPS.

GEM DISSE ANVISNINGER
DENNE BRUGERVEJLEDNING INDEHOLDER VIGTIGE
SIKKERHEDSANVISNINGER

Denne UPS indeholder LIVSFARLIG HØJSPÆNDING. Alle reparationer og
vedligeholdelse bør kun udføres af en AUTORISERET SERVICETEKNIKER. Ingen af
UPS’ens indvendige dele kan repareres af brugeren.

쑺 Denne UPS indeholder egen energiforsyning (batterier). Udgangsnetstikkene

kan lede strøm, selv når UPS’en ikke er tilsat en AC-energikilde.

쑺 Netledningen må ikke fjernes og stikket må ikke trækkes ud, mens UPS’en er

tændt. Dette fjerner sikkerhedsjorden fra UPS’en og fra det udstyr, der er
sat til.

쑺 Installér denne UPS i et temperatur- og fugtighedskontrolleret

indendørsmiljø, frit for ledende forureningsstoffer for at formindske risikoen
for brand og elektrisk stød. Rumtemperaturen må ikke overstige 40°C.
UPS’en bør ikke betjenes nær vand eller høj fugtighed (maksimalt 95%).

쑺 I overensstemmelse med internationale normer og bestemmelser for

el-installation må det udstyr, der er forbundet til udgangen af denne UPS,
tilsammen ikke overskride en jordafdelingsspænding på mere end 1,5
milliampere.

Safety Warnings

FARE

ADVARSEL!

ADVARSEL

쑺 Stikkontakten skal være højest 2 meter fra udstyret og skal være tilgængeligt

til operatøren.

쑺 Batterier kan udgøre en fare for elektrisk stød eller forbrændinger

forårsaget af høj kortslutningsspænding. De korrekte forholdsregler bør
overholdes.

쑺 Korrekt bortskaffelse af batterier er påkrævet. Overhold gældende lokale

regler for bortskaffelsesprocedurer.

쑺 Skaf dig aldrig af med batterierne ved at brænde dem. Batterierne kan

eksplodere ved åben ild.

쑺 Batterierne bør aldrig åbnes eller skilles ad. Udløst elektrolyt er skadeligt for

hud og øjne og kan være yderst giftigt.

DEZE HANDLEIDING BEVAT BELANGRIJKE
VEILIGHEIDSINSTRUCTIES

Deze UPS bevat LEVENSGEVAARLIJKE ELEKTRISCHE SPANNING. Alle reparaties
en onderhoud dienen UITSLUITEND DOOR ERKEND SERVICEPERSONEEL te
worden uitgevoerd. Er bevinden zich GEEN ONDERDELEN in de UPS die DOOR
DE GEBRUIKER kunnen worden GEREPAREERD.

WAARSCHUWING

쑺 Deze UPS bevat zijn eigen energiebron (batterijen). De uitgangsaansluitingen

kunnen onder spanning staan wanneer de UPS niet op een wisselstroom
voeding is aangesloten.

쑺 Verwijder de ingangsnoer niet of haal de stekker van de ingangsnoer er niet

uit terwijl de UPS aan staat. Hierdoor zou de UPS en uw aangesloten
apparatuur geen aardebeveiliging meer hebben.

쑺 Teneinde de kans op brand of elektrische schok te verminderen dient deze

UPS in een gebouw met temperatuur- en vochtigheidregeling te worden
geïnstalleerd, waar geen geleidende verontreinigingen aanwezig zijn. De
omgevingstemperatuur mag 40°C niet overschrijden. Niet gebruiken in de
buurt van water of bij zeer hoge vochtigheid (max. 95%).

쑺 Om aan de internationale normen en bedradingsvoorschriften te voldoen

mag de gehele apparatuur die op de uitgang van deze UPS is aangesloten,
geen aardlekstroom van meer dan 1,5 milliampère hebben.

GEVAAR

OPGELET

쑺 De hoofdvoedingcontactdoos moet zich op minder dan 2 meter vande

apparatuur bevinden en makkelijk bereikbaar zijn voor de gebruiker.

쑺 Batterijen kunnen gevaar voor elektrische schok of brandwonden

veroorzaken als gevolg van un hoge kortsluitstroom. Volg de desbetreffende
aanwijzingen op.

쑺 De batterijen moeten op de juiste wijze worden opgeruimd. Raadpleeg

hiervoor uw plaatselijke voorschriften.

쑺 Nooit batterijen in het vuur gooien. De batterijen kunnen ontploffen.
쑺 Nooit batterijen openen of verminken. Vrijkomend elektrolyt is schadelijk

voor de huid en ogen, en kan uiterst giftig zijn.
