CHAPTER 1: GENERAL
UPS/NTA GB/DELMP_EXPC1C3C6_B 5
1.1 SCOPE
This document provides required information for operating DELPHYS MP and DELPHYS MP
elite systems. It describes the facilities offered 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 configurations, i.e.:
- Single UPS’s with bypass
- Modular systems
- Central bypass systems
1.2 PURPOSE AND UPS COMPOSITION
DELPHYS MP and DELPHYS MP elite 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 fitted 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 MP and DELPHYS MP elite provide three-phase sinusoidal output. The UPS is
composed of:
- 1 fully controlled three-phase rectifier with 6 thyristors or IGBT (DELPHYS MP elite),
- 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 control panel made up of a mimic panel, an 8-line display and an intuitive user interface.
UPS/NTA GB/DELMP_EXPC1C3C6_B 6
1.3 SAFETY
CAUTION
ADVICE
The equipment can only be switched on or used if the following conditions
are fulfilled:
- 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....
- Carefully follow the instructions described in this manual.
- All operations must only be carried out by personnel who are
suitably trained and with authorized access to restricted areas.
Caution
CAUTION
DANGER
Do not forget that even when the load is stopped the unit is live:
- because of the mains voltage, the rectifier and the bypass.
- because of the voltage generated by the battery and by the rectifier.
- because of the load voltage when the maintenance bypass Q5 is closed
and the bypass mains is present.
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
rectifier and inverter to discharge.
CAUTION: the residual voltage of the capacitors may still cause
heavy electrical arcs after 5 minutes.
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.

1.4 LAYOUT OF DELPHYS MP AND DELPHYS MP ELITE SYSTEMS
DELPHYS MP DELPHYS MP elite
1.5 POWER SUPPLY INPUTS
Three power supply inputs are needed to operate the system:
- voltage on input 1 for the supply to the rectifier,
- 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 450Vdc).

NOTE: when the process is completed, all the UPS units are stopped.
Do not forget that even when the loads are stopped the units are live:
- because of the utility voltage to the rectifier and the bypass.
CAUTION
- because of the residual voltage of the capacitors.
- because of the load voltage when the maintenance bypass Q5 is closed
and the bypass supply is present.
3.7.5 System with two redundant units
In a system with two redundant units, only one maintenance bypass can be closed.
3.7.6 System with two non redundant units or more than two parallel units
In such a system, the maintenance bypass is common to the whole system.

- successively shutdown the rectifiers (open Q1 if provided).
Note: at this stage the load is supplied by the maintenance bypass (no protection) and the
modules are stopped.
UPS/NTA GB/DELMP_EXPC1C3C6_B 36
4.6.7 Operating a module of the system
Module uncoupling can only be achieved if the system is
redundant, meaning that it can supply all the energy required
to the load with one module disconnected.
4.6.7.1 Uncoupling of a module
The uncoupling of a module is to be made from its control panel by selecting:
- the menu "UNIT COMMANDS"
- the submenu "UNIT UNCOUPLING" ("cancel" is being displayed)
- press key
- press key ENTER to confirm the request
- open switch Q2
to reach the module uncoupling option
4.6.7.2 Shutdown of a module
In the control panel of the appropriate module, select:
- the menu "SUBSET COMMAND"
- the submenu "INVERTER OFF" and confirm with the ENTER key
- the submenu "RECTIFIER OFF" and confirm with the ENTER key
- open Q1 (if provided) and Q20 (battery protection),
Note 1: operations are identical for all modules.
Note 2: in case of a redundant system, the command is inhibited if the module
uncoupling causes the loss of redundancy; the corresponding alarm is displayed
on the central bypass cabinet.
Do not forget that even when the load is stopped the module is
live:
- because of the input voltage upstream of Q1,
CAUTION
- because of the load voltage coming from the common busbar
downstream of Q2,
- because of the continuous voltage generated by the
capacitors. The safety level is only reached after 5 minutes.
4.6.8 Starting and coupling a module
The startup of the modules is run through an interactive procedure.
In the control panel of the module:
- select the menu "UNIT COMMANDS"
- select the submenu " UNIT AUTOMATIC STARTUP"
- confirm with the ENTER key
- comply with the instructions displayed i.e.:
- close Q1 (if provided) to supply the rectifier
- validate startup with the battery before closing Q20
- close Q2.
Note 1: operations are identical for all modules.
At this point, the module is connected to the common busbar.

5.3 OVERLOAD MONITORING
Principle:
The UPS overload monitoring is based on reference levels (the higher the load rate, shorter the
overload capacity). There are two distinct reference levels:
- the first one corresponds to the overload capacity of the bypass input,
- the second one corresponds to the overload capacity of the inverter.
While operating from the inverter, the load is automatically transferred to the automatic bypass
when the overload capacity reaches 50% and the bypass input is present.
Signalling and automatic actions:
The UPS OVERLOAD alarm is activated if:
- the load rate exceeds 103% ("LOAD ON INVERTER"),
- the load rate exceeds 105% ("LOAD ON MAINS").
The alarm disappears if the load rate drops below 100%
Typical unit overload < 30°C
Overload rate Inverter and byp
110% 60 minutes 60 minutes 30 min + 60 min
125% 10 minutes 10 minutes 5 min + 10 min
150% 1 minute 1 minute 30 sec + 1 min
NOTE: Should an extended overload occur, the static switch warms up, which results in the
disconnection of the load after some time.
If the load is supplied by the bypass input following an automatic transfer, no return to the
inverter is possible as long as the UPS is overloaded and the UPS OVERLOAD alarm has not
been reset.
Automatic bypass Total overload time

inverter + automatic byp
5.4 REMAINING BACK UP TIME
The remaining back up time is displayed on the control panel when the UPS operates from the
battery. The calculation is obtained from the battery capacity and the Ampères per hour (Ah)
consumed by the load.
Text displayed can be set by Commissioning, Inspection and Maintenance Department.
