Upstream and Downstream Protection for IEC

NOTE: For local directives which require 4-pole circuit breakers: If neutral conductor is expected to carry a high current, due to line-neutral non-linear load, the circuit breaker must be rated according to expected neutral current.

The bypass/output breakers 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 breakers are sized based on end-of-discharge voltage which has been defined as 380 VDC.

Preconditions for Live Swap of Power Modules

Live Swap of power modules is only allowed under the following preconditions for the UPS installation; Follow either scenario 1 or scenario 2:

Preconditions for UPS installation – scenario 1 with instantaneous override values and trip times set according to the tables below in Recommended Upstream Protection for IEC	Preconditions for UPS installation – scenario 2 with alternative breaker configurations supported with GVLOPT011 and breaker with ERMS mode*
Circuit breakers must have instantaneous trip time of maximum 60 ms.	Circuit breakers must be installed for input (unit input breaker UIB) and bypass (static switch input breaker SSIB).
Circuit breakers must have instantaneous override values set according to the table below.	Circuit breakers (UIB, SSIB) must be equipped with NEC 240.87, NFPA70E, IEEE1584, or EN51110-1 compliant ERMS mode.
Circuit breakers must be installed for input (unit input breaker UIB) and bypass (static switch input breaker SSIB).	For parallel systems with three or more UPSs: Circuit breakers must be installed for the output (unit output breaker UOB) of each UPS. The unit output breaker (UOB) is sized as the static switch input breaker (SSIB).
For parallel system with three or more UPSs: Circuit breakers must be installed for the output (unit output breaker UOB) of each UPS. The unit output breaker (UOB) is sized as the static switch input breaker (SSIB).	Circuit breaker (UOB) must be equipped with NEC 240.87, NFPA70E, IEEE1584, or EN51110-1 compliant ERMS mode.
Live Swap is not supported for >65kA_bf installations where current limiting disconnect devices are used to protect the UPS.	GVLOPT011 (Galaxy VL door switch kit) must be installed in the UPS and connected so ERMS mode is set to ON on UIB and SSIB and UOB when the front door of the UPS 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 for scenario 1 or scenario 2 are not met.

DANGER
Hazard of electric shock, explosion, or arc flash Only perform Live Swap of the power modules in UPS installations that follow the preconditions for scenario 1 or scenario 2. Failure to follow these instructions will result in death or serious injury.

Recommended Cable Sizes for IEC

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 240 mm². 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:

4 on input/output/bypass busbars
4 x 240 mm² on input/output/bypass busbars
4 x 240 mm² or 8 x 150 mm² on DC+/DC- busbars
8 on N busbar
16 on PE busbar

NOTE: Overcurrent protection is to be provided by others.

Cable sizes in this manual are based on the minimum requirements in table B.52.3 and table B.52.5 of IEC 60364-5-52 with the following assertions*:

90 °C conductors
An ambient temperature of 30 °C
Use of copper or aluminum conductors
Installation method F
Single layer on a perforated cable tray

PE cable size is based on table 54.2 of IEC 60364-5-54.

If the ambient temperature is greater than 30 °C, larger conductors are to be selected in accordance with the correction factors of the IEC.

The bypass/output cables 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 DC cables are sized based on end-of-discharge voltage which has been defined as 380 VDC per IEC 60364.3 Omission of devices for protection against overload.

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

Load Sharing in Bypass Operation in a Parallel System

The impedance of the bypass paths need to be controlled in a parallel UPS system. When operating in bypass mode, the parallel load sharing is determined by the total impedance of the bypass path comprising cables, switchgear, static bypass switch, and cable formation.

Parallel System – Dual Mains

NOTICE
Risk of equipment damage To ensure correct load sharing in bypass operation in a parallel system, the following recommendations apply: The bypass cables must be the same length for all UPSs. The output cables must be the same length for all UPSs. The input cables must be the same length for all UPSs in a single mains system. Cable formation recommendations must be followed. The reactance of busbar layout in the bypass/input and output switchgear must be the same for all UPSs. If the above recommendations are not followed the result can be uneven load sharing in bypass and overload of individual UPSs. Failure to follow these instructions can result in equipment damage.

eConversion Limits for Parallel UPS Systems

eConversion requires a minimum load percentage on the UPS for parallel UPS systems. The minimum required load percentages depend on the power cable sizes.

NOTE: For installations using the recommended cable sizes, refer to this table for the minimum load percentages: Standard eConversion Limits Based on Recommended Cable Sizes.

Standard eConversion Limits Based on Recommended Cable Sizes

UPS rating	Minimum load %
200 kW	34%
250 kW	27%
300 kW	23%
350 kW	19%
400 kW	17%
450 kW	15%
500 kW	14%

The other prerequisites to use this table include:

The values are calculated based on the use of recommended cable sizes.
Installations with maximum two cables on each phase are supported.
The bypass and output cables must have equal length for all UPSs.

NOTE: For certain installations such as installations with 80% breakers or where other installation methods have been applied to comply with the IEC standard, it is possible that non-recommended cable sizes will be used. For installations using non-recommended cable sizes, refer to this table for the voltage rating percentages: Standard eConversion Limits Based on Non-recommended Cable Sizes.

Standard eConversion Limits Based on Non-recommended Cable Sizes

UPS rating	Minimum load %
200 kW	50%
250 kW	40%
300 kW	34%
350 kW	29%
400 kW	25%
450 kW	22%
500 kW	20%

The other prerequisites to use this table include:

The values are calculated based on the scenario of using non-recommended cable sizes.
Installations with three or four cables on each phase are supported.
The bypass and output cables must have equal length for all UPSs.
