1. CERTIFICATE AND CONDITIONS OF WARRANTY
This SOCOMEC continuous power system is guaranteed against any manufacturing or material defects. The warranty
is valid for 12 (twelve) months from the commission date, provided activation is carried out by SOCOMEC personnel or
personnel from a support centre authorised by SOCOMEC, and no more than 15 (fteen)
months from being shipped from SOCOMEC.
The warranty is valid throughout national territory. If the UPS is exported abroad, the warranty will only cover the parts used
to repair faults.
The warranty is valid ex-works and covers labour and parts used to repair the faults. The warranty shall not apply in the
following cases:
• Failure due to unforeseen circumstances or force majeure (lightning, oods, etc.);
• Failure due to negligence or improper use (use outside limits: temperature, humidity, ventilation, electric power supply,
applied load, batteries);
• Insufcient or inappropriate maintenance;
• When maintenance, repairs or modications have not carried been out by SOCOMEC personnel, or personnel from a
support centre authorised by SOCOMEC.
• If the battery has not been recharged in accordance with the terms indicated on the packaging and in the manual, in the
event of long periods of storage or UPS inactivity.
SOCOMEC may, at its own discretion, opt for the repair of the product or the replacement of faulty or defective parts with
new parts, or with used parts of equivalent quality to new parts with regard to function and performance.
Defective or faulty parts replaced free of charge must to be made available to SOCOMEC, which becomes the sole owner.
Replacement or repair of parts, or any modications to the product during the warranty period, will not extend the duration
of the warranty.
SOCOMEC will not be responsible for damages under any circumstances (including, without limitations, damage for loss of
earnings, interruption of activity, loss of information or other nancial losses) arising from the use of the prod- uct.
SOCOMEC retains the full and exclusive ownership rights to this document. Only a personal entitlement to use the
document for the application indicated by SOCOMEC is granted to the recipient of this document. The reproduction,
modication, distribution of this document, either partially or wholly and in any manner, is strictly prohibited except upon

2. SAFETY STANDARDS
This user manual species installation and maintenance procedures, technical data and safety instructions for SOCOMEC.
For further information visit the Socomec website: www.socomec.com.
NOTE!
Any work carried out on the equipment must be performed by skilled, qualied technicians.
NOTE!
Before carrying out any operations on the unit read the installation and operating manual care- fully. Keep this
manual safe for future reference.
NOTE!
The models are not available for all markets. Contact Socomec for further information.
DANGER!
Failure to observe safety standards could result in fatal accidents or serious injury, and damage equipment or
the environment.
CAUTION!
If the unit is found to be damaged externally or internally, or any of the accessories are damaged or missing,
contact SOCOMEC. Do not operate the unit if it has suffered a violent mechanical shock of any kind.
NOTE!
Install the unit in accordance with clearances in order to prevent access to handling devices and guarantee
sufcient ventilation (refer to ‘Environmental requirements and handling’ chapter).
NOTE!
Only use accessories recommended or sold by the manufacturer.
NOTE!
When the equipment is transferred from a cold to a warm place wait approx. two hours before putting the unit
into operation.
NOTE!
When carrying out electrical installation, all standards applicable specied by the IEC, in particu- lar IEC
60364, and the electricity supplier must be observed. All national standards applicable to batteries must be
observed. For further information refer to ‘Technical specications’ chapter.
CAUTION!
A battery can present a risk of electrical shock and high short circuit current. The following precautions should
be observed when working on batteries:
- Remove watches, rings or metal objects.
- Use tools with insulated handles.
- Wear rubber gloves and boots.
- Do not lay tools or metal parts on top of the batteries.
- Disconnect the charging source prior to connecting or disconnecting battery terminals.
- Determine if battery is inadvertently grounded. If inadvertently grounded, remove source from ground.
Contact with any part of grounded battery can result in electrical shock. The likelihood of such shock
can be reduced if such grounds are removed during installation and maintenance (applicable to
equipment and remote battery supplies not having a grounded supply circuit).
WARNING!
Connect the protective earth (PE) conductor before making any other connections.
DANGER! RISK OF ELECTRIC SHOCK!
Before carrying out any operations on the unit (cleaning and maintenance performances, connection of
appliances, etc.) disconnect all power sources.
DANGER! RISK OF ELECTRIC SHOCK!
After disconnecting all power sources wait approx. 5 minutes for the complete discharge of the unit.
NOTE!
The UPS may be powered from an IT distribution system with a neutral conductor.

OFYS RT 1 - 3kVA - 551906A - SOCOMEC
6EN
NOTE!
Installing the equipment correctly guarantees the IP20 protection level
NOTE!
Any use other than the specied purpose will be considered improper. The manufacturer/ supplier shall not be
held responsible for damage resulting from this. Risk and responsibility lies with the system manager.
CAUTION: Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic.
CAUTION: Do not dispose of batteries in a re. The batteries may explode.
WARNING: Care shall be taken not to wear clothes and footwear which may build up electro- static charge.
Absorbing cloth moistened only with water shall be used for battery cleaning. Other cleaning agents may
result in built up of static charge or may damage the battery cases.
NOTE: Only use accessories recommended or sold by the manufacturer.
NOTE: Batteries must only be replaced with batteries recommended or sold by the manufacturer. Batteries
must only be replaced by qualied technicians.
NOTE: The batteries are toxic waste. If the battery cabinet needs to be scrapped it is essential to entrust the
equipment solely and exclusively to rms specialising in the disposal of the materials making up the system.
These are obliged to break up and dispose of the various components in accordance with the legal provisions
in force in the country where the system is installed.
Note: the product you have chosen is designed for commercial and industrial use only. In order to be used for
particular critical applications such as life support systems, medical applications, commercial transportation, nuclear
facilities or any other application or system where product failure is likely to cause substantial harm to people or
prop- erty, the products may have to be adapted. For such uses we would advise you to contact SOCOMEC
beforehand to conrm the ability of these products to meet the requested level of safety, performance, reliability and
compliance with applicable laws, regulations and specications.
NOTE!
This is a product for commercial and industrial application – installation restrictions or additional measures
may be needed to prevent disturbances.
WARNING!
This is a category C3 UPS product. This is a product for commercial and industrial application in the second
environment – installation restrictions or additional measures may be needed to prevent disturbances.
The product falls within the C2 category if one 2.5 kW module is used, therefore in a residential environment it
may cause radio interference and users may be required to take additional meas- ures.
Safety requirements for secondary batteries, battery installations and backfeed protection as well.
The installer is responsible for ensuring that the battery installation and their operating environ- ment conform
to national and international codes and safety standards.
