The warranty terms and conditions are stipulated in the offer, by default the following clauses apply.
The SOCOMEC UPS warranty is strictly limited to the product(s) and does not extend to equipment which may
be integrated with this/these product(s), nor the performance of such equipment.
The manufacturer guarantees its products to be free from manufacturing faults and defects in design, material
or workmanship, subject to the limits set forth below.
The manufacturer reserves the right to modify the delivery with a view to fullling these guarantees or to replace
defective parts. The manufacturer's warranty does not apply in the following cases:
•fault or defect in the design of parts added or supplied by the customer
•fault due to unforeseen circumstances or force majeure
•replacement or repair resulting from normal wear and tear of the modules or machinery
•damage caused by negligence, lack of proper maintenance or misuse of the products
• repair, modication, adjustment or replacement of parts undertaken by unqualied third parties or person-
nel without the express consent of SOCOMEC UPS.
The warranty period is twelve months commencing from the date of delivery of the product.
The repair, replacement or modication of the parts during the warranty period does not imply or justify any
extension of the warranty beyond the original period.
In order to establish a valid warranty claim, the purchaser must notify the manufacturer in writing immediately
after the discovery of any apparent material defects and provide any and all supporting evidence of the defects
at the latest within eight days before the date of expiry of the warranty.
Defective parts which have been returned and replaced free of charge shall become the property of SOCOMEC UPS.
The warranty is void if the purchaser has undertaken modications or repairs on the devices on his or her own
initiative and without the express consent of the manufacturer.
The manufacturer's responsibility is strictly limited to the obligations dened in this warranty (repair and replace-
ment) excluding any other right to claim compensation or indemnity.
Any import tax, duty, fee or charge of any nature whatsoever imposed by European regulations or those of an
importing country or of a transit country shall be paid by the purchaser.

DELPHYS MX 250-900 - Ref.: OPMDELMX1010-GB_01
We thank you for the trust you have in our Uninterruptible Power Systems.
This equipment is tted with up to date technology. Rectier and inverter subsets are provided with power semicon-
ductors (IGBT) including a digital micro-controller.
Our equipment complies with standard IEC EN 62040-2 and 62040-1.
“This is a product for restricted sales distribution to informed partners. Installation restrictions or addi-
tional measures may be needed to prevent disturbances”.
SAFETY REQUIREMENTS
Using conditions:
Do read carefully these operation instructions before using the UPS and comply with the safety notes mentioned.
Whatever the repairs, they must be made only by authorised staff, who have been suitably trained. It is recommend-
ed that the ambient temperature and humidity of the UPS environment are maintained below the values specied by
the manufacturer.
This equipment meets the requirements of the European directives applied to this product. As a consequence it is
labelled as follows:
REGULATIONS CONCERNED WITH ENVIRONMENTAL ISSUES
Recycling of electrical products and equipment
Provision is made in European countries to break up and recycle materials making up the system. The various com-
ponents must be disposed of in accordance with the legal provisions in force in the country where the system is
installed.
Battery wastes
Used batteries are considered as toxic wastes. It is therefore essential to entrust them solely and exclusively to rms
specialised in their recycling. They can not be treated with other industrial or household wastes, as set out in local
regulations in force.

3. GENERAL
3. 1.
Scope
This document provides required information for operating DELPHYS MX systems. It describes the facilities of-
fered on the control panels:
•Scrolling through the menus displayed
•Load transfer onto the automatic and/or maintenance bypass
•System start up or shutdown
The operating instructions refer to the most frequently used congurations, i.e.:
•Single UPS’s with bypass
•Modular systems
•Central bypass systems
3. 2.
purpoSe And upS compoSition
DELPHYS MX provide:
•very low distortion and high power factor to the upstream power supply,
•voltage and frequency stability as well as continuity of supply to downstream loads –whatever the outages
or disturbances on the upstream power supply-.
The system is tted with double conversion VFI-SS-111 technology.
When the input power supply is present, the UPS acts as a stabilizer. In the event of a utility outage, it acts as
a source of electrical power. In such case, the required power is supplied by the battery, which is kept charged
when the mains is present.
DELPHYS MX provide three-phase sinusoidal output. The UPS is composed of:
•1 fully controlled three-phase rectier of DBC type (Double Bridge Converter),
•1 three-phase inverter of S.V.M. type (Space Vector Modulation),
•1 static bypass to transfer the load automatically and without interruption to the bypass supply.
•1 maintenance bypass, which allows a seamless load transfer to the mains during maintenance operations,
•1 battery,
•1 DC/DC converter for recharging the batteries,
•1 control panel made up of a mimic panel, an 8-line display and an intuitive user interface.

CAUTION
The equipment can only be switched on or used if the following conditions are fullled:
•electrical connections comply with the regulation in force (earth bonding, appropriate protections and cross-
section of cables)
•all means to comply with the protection index of the system are in place, such as side panels, doors,
glands, shields or whatever....
ADVICE
•Carefully follow the instructions described in this manual.
•All operations must only be carried out by personnel who are suitably trained and with authorized ac-
cess to restricted areas.
CAUTION
Do not forget that even when the load is stopped the unit is live:
•because of the mains voltage, the rectier and the bypass.
•because of the voltage generated by the battery and by the rectier.
•because of the load voltage when the maintenance bypass Q5 is closed and the bypass mains is present.
DANGER
Any operation inside the cabinets is to be completed:
•once the UPS is stopped and no longer live
•after 5 minutes, the time for the capacitors upstream of the rectier and inverter to discharge.
the residual voltage of the capacitors may still cause heavy electrical arcs after 5 minutes.
HAzARD INDICATION
While the UPS is operating, this label indicates that the parts are live and therefore the risk of electrical hazard.
All operations behind protection panels must only be carried out by personnel who are suitably trained.
3. 4.
power Supply inputS
Three power supply inputs are needed to operate the system:
•voltage on input 1 for the supply to the rectier,
•voltage on input 2 for the supply to the automatic bypass (depending on the system, inputs 1 and 2 can be common),
•the DC voltage for the battery (about 500Vdc).
