Upstream and Downstream Protection for UL

Preconditions for Live Swap of Power Modules

Live Swap of power modules is only allowed under the following preconditions for the UPS system installation:

Circuit breaker must be installed for input (unit input disconnect device UIB).
Circuit breaker (UIB) must be equipped with NEC 240.87, NFPA70E, IEEE1584, or EN51110-1 compliant ERMS mode.
GVLOPT011 (Galaxy VL door switch kit) must be installed in all four UPSs in the UPS system and connected so ERMS mode is set to ON on UIB when the front door of any of the UPSs is opened.
In ERMS mode, the instantaneous trip current shall be set to 5000 A or less. All time-delay settings shall be set to zero.

Schneider Electric reserves the right to remove the Live Swap label from the product front if the preconditions are not met.

DANGER
Hazard of electric shock, explosion, or arc flash Only perform Live Swap of the power modules in UPS system installations that follow the preconditions listed above. Failure to follow these instructions will result in death or serious injury.

Recommended Upstream and Downstream Protection for UL

The output breakers are sized based on the nominal current +10%. This is to accommodate either low grid voltage or deviation in cable length between parallel UPSs. The battery breakers are sized based on the end-of-discharge voltage which has been defined as 380 VDC.

NOTE: Overcurrent protection is to be provided by others and marked with its function.

Recommended Cable Sizes for UL

DANGER
hazard of electric shock, explosion, or arc flash All wiring must comply with all applicable national and/or electrical codes. The maximum allowable cable size is 600 kcmil. Shrink sleeve must be fitted over cable lug crimped zone and must overlap with the cable insulation on all power cables. Failure to follow these instructions will result in death or serious injury.

The maximum number of cable connections per busbar in the I/O cabinet:

9 x 600 kcmil on input busbars
7 x 600 kcmil on output busbars
20 x 600 kcmil on DC+/DC- busbars
16 on N busbar
24 on grounding busbar

NOTE: Overcurrent protection is to be provided by others.

Cable sizes in this manual are based on Table 310.15 (B)(16) of the National Electrical Code (NEC) with the following assertions*:

90 °C (194 °F) conductors (75 °C (167 °F) termination)
An ambient temperature of 30 °C (86 °F)
Use of copper conductors

If the ambient temperature is greater than 30 °C (86 °F), select larger conductors in accordance with the correction factors of the NEC.

Equipment grounding conductors (EGC) are sized in accordance with the minimum requirements in NEC Article 250.122 and Table 250.122.

NOTE: 100% rated circuit breakers for UIB, SIB, MBB disconnect devices. 100% rated circuit breakers for battery disconnect devices.

The output cables are sized based on the nominal current +10%. This is to accommodate either low grid voltage or deviation in length between parallel UPSs. The battery cables are sized based on end-of-discharge voltage which has been defined as 380 VDC.

Guidance for Organizing Input and Output Cables

The input and output cables must be grouped in circuits. On raceways, use one of the two shown cable formations.

eConversion Limits for Parallel UPS Systems

eConversion requires a minimum load percentage on the Galaxy VL 1600-2000 kW UPS system. The minimum required load percentages depend on the power cable sizes.

Standard eConversion Limits Based on Recommended Cable Sizes

UPS rating	Minimum load %
1600 kW	10%
1800 kW	10%
2000 kW	10%

Load Sharing in Balance and Unbalance Scenarios in Bypass Operation or eConversion Mode

In double conversion (normal operation), the load sharing between the UPSs in the UPS system is equal as the inverter controls the output current and voltage. However, when the UPS system is commanded to transfer to eConversion (requested bypass), the load sharing is determined by the UPS system impedances (busbars, SCRs). This means that the entire power path from the common input point to the common output point influences the load distribution. This scenario is not unique to this specific UPS system and is applicable to any UPS system.

During eConversion mode or requested bypass operation, if any UPS in the UPS system experiences a load exceeding 100%, it will automatically transfer back to inverter mode as per the design. This ensures the protection and stability of the system.

NOTE: Unbalanced current may occur in bypass operation or in eConversion mode due to the varying impedances in the power path. It is essential to monitor and manage these conditions to maintain UPS system reliability and performance.
