MGETM GalaxyTM 6000 : Specification guide
Parallel UPS, three-phase, 250 to 3000 kVA*
* Power rating for an N+1 redundant configuration
5.6 - System earthing arrangement
The UPS shall be compatible with the following system earthing arrangements:
ωupstream source
…[ TT/ IT / TNS / TNC ]…
ωdownstream installation …[ TT/ IT / TNS / TNC ]…
If the upstream and downstream earthing arrangements are different, galvanic isolation shall be provided on the
6 - Mechanical characteristics
6.1 - Mechanical structure
UPSs and batteries shall be installed in cabinet(s) with a degree of protection IP20 (standard IEC 60529). Access to the subassemblies making up the system shall be exclusively through the front.
…………………………………………………………………………………………
6.2 - Modular design
The UPS system shall be designed to allow the installed power to be easily increased on site by connection of additional UPS units, either to meet new load requirements or to enhance system availability by introducing redundancy.
This transformation shall be possible directly on site, without returning the equipment to the factory and without causing excessive system downtime.
6.3 – Dimensions
The UPS shall require as little floor space as possible. To gain space, it shall be possible to install the UPS with the back to the wall.
6.4 - Connection
To facilitate connections, all terminal blocks must be easily accessible from the front when the UPS is installed with the back to the wall. Entry of upstream and downstream power cables, as well as any auxiliary cables, shall be possible through the bottom for a false floor.
The UPS shall be equipped with an
The cables shall comply with the standards listed in section 12 "Standards and tests" and be mounted in compliance with the stipulations in section 6.6 "Safety". The neutral conductor shall be oversized for any
6.5 - Ventilation
The UPS units shall be provided with
To facilitate positioning of UPS units (back to the wall), ventilation shall take place through the top with an air intake on the front.
6.6 - Safety
For the safety of maintenance personnel, the cabinet shall be provided with a manually operated mechanical bypass designed to isolate the rectifier, charger, inverter and static switch while continuing to supply the load from the bypass AC source.
It shall be possible to send to the UPS an external EPO order resulting in opening of the battery circuit breaker and the upstream circuit breaker.
