Page 3: Purpose
Master HE is a series of UPSs designed entirely by Riello UPS a leading manufacturer of uninterruptible power supplies from 350 VA to 800 kVA, with over 25 years of experience in the sector. -
Page 4: Applications
A PP L IC A T IO N S The UPSs of the Master HE series are suitable for all applications requiring protection of the critical load, from simple installations to more complex systems where a higher level of reliability and maintainability is required. -
Page 5: Configurations
MASTER HE 5. C O N FI G UR A TI O N S The following configurations are available: Single UPS The single version of the system, normally used for simple installations, can be extended to up to 8 units to satisfy increases in load power or to introduce a level of redundancy. - Page 6 MASTER HE The units exchange information on the operating status and the sync signals by the connections in loop with dual redundancy. This means that even in the event of the accidental interruption of both connections, only the UPS affected by this interruption cuts itself off, while the other one continues to operate without any interference.
- Page 7 • Battery can be arranged as common or separate (same as distributed parallel system) • Maintenance bypass is part of the system either embedded in Riello UPS solution (Fig. 1) or supplied by the customer together with all Input/Output/distribution switches (Fig. 2) This manually control switch will enable the load feeding directly from the mains insulating the UPS whenever there is an intervention on its critical parts.

System configuration with centralized bypass without: NOTE: It is warmly suggested to arrange a proper on site procedure (written or via castell key mechanical interlock) so that SWOUT can be open just after SWBY opening manoeuvre.

- Page 9 MASTER HE Dual Bus System (UGS) Two independent systems can be configured in Dual Bus with a single or separate power source. The synchronization option (UGS) keeps the outputs of the two systems constantly synchronized, regardless of the input variations and when the system is powered by the battery. Each system comprises up to a maximum of 8 parallel UPSs.
- Page 10 MASTER HE Dynamic Dual Bus System (PSJ) Two independent systems (up to 4 units each) can be connected in a “Dynamic Dual Bus” configuration by means of the PSJ (Parallel System Joiner) option. This enables the two systems to be joined to form a single system when, for example, part of one system is undergoing maintenance and it is felt appropriate to use the redundant UPS for both bars of the load.

MASTER HE 6. UP S D ESC R I PT I O N The uninterruptible power supply can be set to operate in four operating modes: ON-LINE, STAND-BY ON, SMART ACTIVE and STAND-BY OFF. Mode: ON-LINE • Normal Operation: The rectifier draws energy from the mains to power the inverter and keep the batteries charged;... -
Page 12: Ac/Dc Converter
MASTER HE 6.1. AC/DC Converter The AC/DC Converter converts the alternate voltage into direct voltage to power the inverter at nominal load and to charge the batteries. The input stage of Master HE UPS is realized with a technology such as to reduce the harmonics of current rejected into the mains by up to 3% and increase the power factor up to the unit from 10 to 100% of the load (see the tables with the Technical Data at the end of the present specifications). -
Page 13: Dc/Dc Converter
MASTER HE • Inhibition of bypass synchronism: in case of the generator set with a very unstable output frequency, the Inverter synchronization with bypass can be inhibited. In such as case the inverter generates an output voltage in the free running mode by using the internal oscillator. Consequently, the transfer of the load on the bypass is not allowed. - Page 14 MASTER HE Frequency regulation The inverter output frequency is generated autonomously by an internal oscillator in synch with that of the by-pass mains; the frequency stability towards the load therefore depends on the operating conditions: a) Frequency stability a. With mains available: the internal oscillator follows the variations in frequency of the by-pass mains, according to the set value, which is normally ±2% (can be calibrated form ±1% al ±6%).

MASTER HE 6.3. Static switch The Static Switch is an electronic device that transfers the load onto the by-pass mains without any break in power in the following circumstances: a) manual shutdown of the inverter; b) exceeding of the inverter overload limits; c) exceeding of the internal over temperature limits;... -

This allows 2 systems connected in a “DUAL BUS” configuration to keep synchronised with each other for any variation in the mains voltage, including total failure. The UGS also allows an RIELLO UPS to be synchronised with another power source or to an independent non RIELLO UPS system, even one of a different power rating. -
