UPS/NTA GB/DSEXPC1.F - page 3 1. SAFETY

ADVICE - Carefully follow the instructions described in this manual. - All handling must only be carried out by personnel who are

suitably trained .

CAUTION

Do not forget that even when the load is stopped the unit is live : - because of the mains voltage the rectifier and the by-pass. - because of the voltage generated by the battery and by the rectifier. - because of the load voltage when the manual by-pass Q5 is closed and

the by-pass mains is present.

DANGER

- Once the UPS is disconnected, wait 5 minutes for the capacitors to discharge.

- the residual voltage of the capacitors may still cause heavy electrical arcs after 5 minutes.

2. PURPOSE AND UPS COMPOSITION

The DELPHYS DS static supply protects the connected load, and maintains : - the supply continuity, - the voltage stability, - the frequency stability, whatever outages or disturbances on the upstream mains.

When the upstream mains is present, the UPS acts as a stabilizer. In the event of a mains failure, 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. The UPS provides single-phase or three-phase sinusoidal output. The UPS is composed of : - 1 fully controlled three-phase rectifier, - 1 single-phase or three-phase P.W.M. (Pulse Width Modulation) inverter, - 1 static by-pass to transfer the load automatically and without interruption to the mains in the

event of an overload, - 1 manual by-pass which allows a break-free load transfer to the mains during maintenance

handling, - 1 battery, - 1 control panel made up of a mimic panel, an 8-line display and an intuitive user interface.

8. FLOATING CORRECTION ACCORDING TO THE TEMPERATURE

DELPHYS DS UPSs can be fitted with a temperature probe enabling the adjustment of the rectifier floating voltage according to the battery ambient temperature. This feature ensures a greater reliability of the battery life.

Floating voltage values are to be used in accordance with the data provided by the battery manufacturer.

Equipment required : An additional temperature probe (provided as a standard in our cabinets) mounted in the battery room and connected to the unit on the "input - output FU610" interface PCB.

Principle :

- Battery manufacturers impose an accurate floating voltage per cell for a given temperature,

usually 2,25V/cell at 25°C or 2,27V/cell at 20°C. - Between 0 and 45°C, the floating voltage is adjusted according to a « slope » that can be set

by the factory for each type of battery. This slope can range from 2mV to 8mV/°C/cell. - The battery temperature displayed on the control panel can vary from 0 to 75°C. - In case the ambient temperature exceeds 45°C, the floating voltage remains at the floating

value of 45°C.

UPS/NTA GB/DSEXPC1.F - page 24 An alarm for the battery is given : - if the temperature exceeds 40°C, - if the temperature sensor or the connection system fails. Example :

9. OVERLOAD MONITORING

9.1. In mode normal

Principle : The UPS overload monitoring is based on reference levels. The overload principle can be compared to a tank, filling up more or less rapidly. 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 UPS overload < 30°C (load on inverter)

Overload rate Transfer to mains is possible Transfer to mains is impossible 110% 30 minutes 60 minutes 125% 10 minutes 10 minutes 150% 30 seconds 1 minute

NOTE : Should an extended overload occur, the static contactor warms up which results in the disconnection of the load after some time. If the load is supplied by the by-pass mains 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.


9.2. In eco mode The UPS OVERLOAD alarm is activated when the load rate exceeds 105%. In such a case, the static contactor warms up. When the by-pass general alarm is given, the static contactor stops conducting and the load is therefore no longer supplied.

10. REMAINING BACK UP TIME The remaining back up time is displayed on the control panel when the UPS operates in autonomy. The calculation is obtained from the battery capacity and the Ampères per hour consumed by the load.
