MGETM GalaxyTM 6000 : Specification guide
Parallel UPS, three-phase, 250 to 3000 kVA*
* Power rating for an N+1 redundant configuration
7 - Environment conditions
7.1 - UPS (not including battery)
7.1.1 - Operation
The UPS, not including the battery, shall be capable of operating under the following environmental conditions without loss of performance:
ωambient temperature range: 0° C to +40° C.
ωrecommended temperature range: +20° C to + 25° C;
ωmaximum temperatures: 40 °C for 8 hours
ωmaximum relative humidity: 95% at 25° C;
ωmaximum altitude: 1000 meters.
7.1.2 - Storage
The UPS, not including the battery, shall be designed for storage under the following conditions:
ωambient temperature range:
8 - Protection
8.1 - UPS
Each UPS unit shall include protection against
8.2 - Rectifier and charger
Each rectifier/charger shall be equipped to receive an external order to automatically shut down under the following circumstances:
ωemergency off; in this case, the shutdown will be accompanied by opening of the battery circuit breaker;
ωbattery room ventilation fault.
The rectifier and the charger shall automatically shut down if the DC voltage reaches the maximum value specified by the battery manufacturer.
8.3 - Inverter
The load shall be protected against any overvoltages that could result from voltage regulation failure at the output of the inverters.
The inverter (and the corresponding rectifier/charger) shall automatically shut down if the DC voltage reaches the minimum value specified by the battery manufacturer.
Each inverter shall be equipped with an automatic shutdown system to protect its power circuits against overloads exceeding
8.4 - Batteries
8.4.1 - Protection against deep discharge and self-discharge
The UPS shall comprise a device designed to protect the battery against deep discharges, taking into account the characteristics of the discharge cycles, with isolation of the battery by a circuit breaker.
8.4.2 - Independent regulation and monitoring systems
A regulation system shall regulate the battery voltage and the charge current.
A second system, independent of the regulation, shall monitor the battery voltage and the charge current. Consequently, if the regulation system fails, the monitoring system steps in to shut down the charger and avoid overcharging.
8.4.3- Regulation of the battery voltage depending on the ambient temperature
A temperature sensor adapts the charge voltage to the ambient temperature.
This regulation system takes into account the chemical reaction and prolongs the battery service life. The permissible temperature range is set in the personalisation parameters.
An alarm shall be issued for temperatures outside the permissible range.
8.4.4- Self-test
Battery monitoring shall be carried out by an automatic device.
