PURPOSE
The aim of these specifications is to provide:
• the information required to choose the right uninterruptible power supply for a specific application.
• the information required to prepare the system and installation site.
The specifications are intended for:
• installation engineers.
• design engineers.
• engineering consultants.

1.1. Range
Delphys MX integrates the latest and most powerful generation of Insulate Gate Bipolar Transistors (IGBTs). The use of microproces-
sors increases the number of functions for more secure operation.
The implementation of cutting-edge technology such as Surface Mounted Technology (SMT) has reduced the number and size of
the circuit boards. This reduction in the number of components enhances the reliability of Delphys MX by increasing its resistance
to electromagnetic disturbances.

Delphys MX has been specifically designed to meet the demands of loads in specific application contexts, in order to optimise the
features of the product and to facilitate its integration within the system.

2. FLEXIBILITY
2.1. Power ratings from 250 to 900 kVA
The equipment has been designed with a minimum direct and indirect footprint (the actual space occupied by the unit and the space
required around it for maintenance, ventilation and access to the operating mechanisms and communication devices). The careful
design also provides easy access for maintenance and installation.
All of the control mechanisms and communication interfaces are located in the upper front part and can be accessed from the door.
The air inlet is on the front, with outflow to the rear only; this means other equipment or external battery enclosures can be placed
alongside the UPS unit.

2.2. Flexible backup time
Selection of the back-up time is flexible thanks to the wide range of DC bus voltages. The batteries are organised internally into
racks based on their relative sizes, so as to ensure a compact unit while still guaranteeing substantial backup times. To guarantee
maximum back-up time availability and battery life, the Delphys MX includes Expert Battery System (EBS), smart battery charging
management and BHC Universal (Battery Health Check) to optimise the battery lifetime (available on request).
2.3. Parallel
Delphys MX consists of modular UPS units (rectifier, battery, inverter and bypass) connected in parallel (up to 6 UPS units). This
solution, which is ideally suited for 1+1 redundancy, offers flexible power upgrading and enables stand-alone UPS units to be expan-
ded, even if this was not planned in the original design of the system.
Each UPS unit has a built-in maintenance bypass.
It is possible to add an external maintenance bypass, common to all of the UPS units, for maintenance access.

3.1. Communication interfaces
Delphys MX can manage various different serial, contact and Ethernet communication channels at the same time:
The various cards and signalling accessories can be housed in the communication slots mounted as standard on all models. This
provides Delphys MX UPS systems with a highly flexible interface for the purposes of integration at a later stage after installation,
also in terms of hot switching and with no need for specialist personnel.

Connection to the mains power supply and to the load(s) must be made using cables of suitable size, in accordance with current
standards. If not already present, an electrical control station which can isolate the network upstream of the UPS must be installed.
This electrical control station must be equipped with a circuit breaker (or two, if there is a separate bypass line) of an appropriate
rating for the power draw at full load, and a residual current circuit breaker.
Current flowing to earth varies depending on the size of the UPS, therefore installation engineers must install a residential current
circuit breaker of an appropriate rating upstream of the UPS using a selective model (not sensitive to transitory currents).
Potential dispersion of current from utilities downstream of the UPS should be added to that discharged from the UPS, and it should
also be noted that current peaks are also reached, albeit very briefly, during transitory phases. It is recommended to isolate the
residual current circuit breaker by adding 30mA protection downstream of the UPS on power lines to utilities.
We also recommend checking first for any earth leakage current with an uninterruptible power supply installed and running at the
final load to prevent any untimely tripping of the breakers.
If an external manual bypass is required, only the model supplied by the manufacturer must be installed.
See the relevant table for the data on the cable size and safety devices required.
For detailed information, see the installation and operating manual.
