WARNING: EQUIPMENT DISPOSAL

Out of service units: It is strongly recommended to dispose this piece of equipment according to valid directives in your

country. At the moment of disposing all pieces need to be managed appropriately to avoid possible environmental damage or for
some materials to be recycled.

Batteries : Do not throw it to fire (risk of explosion). Do not open the batteries, there are dangerous liquids inside

WARNING: BATTERIES MAINTENANCE

• Batteries capacity, in general (of all kinds), decrease with time and use.

• Our products contain high quality batteries only.

• Batteries useful life in our UPS is between 4 and 5 years, considering environment temperature under 25 ºC and optimal

operational conditions. This time can be dramatically reduced by high temperature and other adverse operation
condition.

• Batteries life expectancy may be also affected by other operation conditions such as electrical service quality as well as
number and kind of equipments connected to UPS

• Batteries should be periodically tested to check capacity and assure and appropriate back up.

• To enlarge batteries life expectancy it is recommendable to fully discharge UPS one every 2 to 3 months

• During UPS storage recharge batteries according to the following table:

Storage Temperature Recharging Frequency Recharging Time

-25°C a +30°C Every 4 months During 6 hours

+30°C a +45°C Every 2 months During 6 hours

SAFETY INSTRUCTIONS

WARNING: Before revising this section you must read and understand very well section 1 of this manual: “GENERAL SAFETY
INSTRUCTIONS”.

WARNINGS, RECOMMENDATIONS AND LIABILITY LIMITATION

REACH AND LIABILITY LIMITATION: The preparation of the site, wiring and all protection devices must be supplied by end user and it will not

be responsibility neither the UPS distributor nor the UPS technician in charge of the start-up.
The place will be conditioned be end user or electrical contractor and must fulfill with local normative and directives and UPS technical
requirements.
This manual describes minimal conditions and technical requirements with which the site must accomplish.
Directives and requirements described in this manual, do not pretend to substitute in any way local electrical directives or normative.
In some cases, local directives or regulations might be more exigent than UPS technical requirements described by this manual. In that case
end user electrical contractor must be sure to comply with all related local electrical regulations and directives.

WARNING: Power lines must be protected by protection devices against over current (breakers) or leak currents with capacity and technology

appropriate to effectively accomplish its function. Moreover, installation grounding must be correct.

WARNING: Install the UPS in well ventilated locations and leave room enough between UPS and close objects and structures

WARNING: Do not connect to UPS equipments or devices that exceed its capacity, this would overload the UPS.

WARNING: This product has been designed to be used indoors protected from water, direct sun light, dust and extreme temperature.

WARNING: Do not put any object on the UPS; do not apply any force over UPS. Do not cover UPS ventilation.

WARNING: This UPS must be connected to appropriate electrical service according to selected model. Technical specs sticker in the UPS

shows the UPS power ratings. DO NOT connect this UPS to any of its own power outlets, this could damage the unit permanently.

WARNING: Connect only computer related equipments to this UPS. DO NOT connect medical equipments or critical availability equipments to

this UPS. DO NOT connect AC motor based equipments. DO NOT connect home appliances (ovens, vacuum cleaners, refrigerators, etc.) to this

SITE INSPECTION AND INSTALLATION CONDITIONS

REGULATIONS AND LEGAL DIRECTIVES

It is necessary to check that installation site, wiring and power protection in the installation supplied by end user, fulfill technical parameters
required by UPS.
A particular installation might accomplish with UPS requirements but not with local directives and regulations.
The end user and/or electrical contractor will be responsible of watching for complying with electrical regulations and normative during electrical
installation managed by end user.
Inspection performed by installation technician is not intended to confirm regulations and directives accomplishing but only with technical needs
for optimal UPS operation.

SITE INSPECTION

• During transport of this UPS from a cold place to a warmer and more humid one, some condensation could be generated. Leave the

UPS for at least 2 hours to climate to new installation site.

• Do not install the UPS outdoors or near water sources nor in wet environment

• Do not install the UPS in sites exposed to sun light or heat sources. Temperature at operation site should never rise over 35 ºC.

Batteries’ life shortens over 25 ºC.

• Installation site must be dry, fresh, free of dust, fibers and any other objects (conductors or not) suspended in the air that could get

into the UPS thru the ventilation system (Fan).

• Do not block UPS ventilations

UPS INPUT AND OUTPUT POWER LINES PROTECTION

AC LINES PROTECTIONS DEVICES:

All UPS Inputs and outputs must be protected by circuit breakers and current leak protections. Protection capacity and type must fulfill local
regulations as well as directives from this manual. Grounding must be according to local directives as well.

DC PROTECTIONS DEVICES:

For Ex models (with external batteries) there must be also DC Circuit Breakers between UPS and battery bank.
Some Models include a DC breaker on the rear panel for external battery pack protection; otherwise an external DC Circuit breaker must be
installed.

MATERIALS AND ELECTRICAL DEVICES

WARNING: Verify that all electrical lines involved in installation are open circuits and free of dangerous voltages before starting inspection

tasks. All switches related to these electrical lines must be in “OFF” position before starting UPS installation. After disconnecting power from
electrical lines involved in installation, check again with a digital voltmeter that are free of dangerous voltages.

IMPORTANT: Warning label must be placed on primary involved circuit breakers to alert there are maintenance personnel working on these
circuits to avoid accidental actuation on involved breakers.

TOWER UPS INSTALLATION

SITE CONSIDERATIONS

* This product has been designed to be used indoors, protected from water, direct sun light, dust and extreme temperature.
* Install the UPS in well ventilated location or air conditioned room. Temperature must be always in acceptable range according to technical
specifications table of this manual. It is strongly recommendable controlled room temperature between 21ºC to 24ºC for longer battery and UPS
life.
* There must be minimum 1 meter free room distance between UPS and any wall or object. It will allow better ventilation and it will allow
service UPS when required.
* Do not put any object on the UPS; do not apply any force over UPS. Do not cover UPS ventilation.

ELECTRICAL REQUIREMENTS (MANDATORY)

* All Power lines must be protected by magneto-thermal protection devices against over current (breakers) with capacity and technology
appropriate to effectively accomplish its function as indicated in this manual. Moreover, installation grounding must be correct.
* This UPS must be connected to appropriate electrical service according to selected model. Technical specs sticker in the UPS shows the UPS
power ratings. DO NOT connect this UPS to any of its own power outlets, this could damage the unit permanently.
* If external battery cabinets are connected to UPS, it is necessary to install one DC breaker between UPS and each external battery cabinet.
Original External Battery cabinets normally include its own input breaker.

LEAK CURRENT PROTECTION

In many countries, now a day, it is legally required to install protections against current leakage to protect human beings in cases of leaks o
discharges to ground. It is responsibility of the end user and/or electrical contractor selecting and including these protection devices in the
electrical circuit of the UPS.
