OBJECTIVES
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.
INSTALLATION REQUIREMENTS AND PROTECTION
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.
If an external manual bypass is required, only the model supplied by the manufacturer must be installed.
We recommend fitting two metres of unanchored flexible cable between the UPS output terminals and the cable anchor (wall or
cabinet). This makes it possible to move and service the UPS.
For detailed information, see the installation and operating manual.

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:

•theairinletisonthefront,withoutflowfromtheupperside;thismeansotherequipmentorexternalbatteryenclosurescanbe

FLEXIBILITY
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:
•EBS (Expert Battery System), smart battery charging management.
2.3. Parallel
DELPHYS MX UPS units (rectifier, battery, inverter and bypass) can be connected in parallel (up to 6 units) with distributed or central
bypass. This solution, which is ideally suited for 1+1 redundancy, offers flexible power upgrading and enables stand-alone UPS units
to be expanded. Each single UPS unit has a built-in maintenance bypass (single unit or distributed bypass).
It is possible to add an external maintenance bypass, common to all of the UPS units, for maintenance access.

(1) Rectifier protection should only be considered in the event of separate inputs. The bypass protection is given by recommendation.
When the bypass and rectifier inputs are combined (common input), the general input protection rating must be the highest of both
(bypass or rectifier).
(2) Must be selective with residual current circuit breakers downstream of the UPS connected to the UPS output. If the bypass network
is separate from the rectifier circuit, or in the event of parallel UPS, use a single residual current circuit breaker upstream of the UPS.
