Upstream and Downstream Protection

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.

NOTE: For local directives which require 4-pole circuit breakers: Refer to the earthing diagrams for details about neutral connection.

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 308 VDC.

Required Upstream Protection for 380/400/415 V (IEC) and Minimum Prospective Phase-To-Earth Short Circuit at the UPS Input/Bypass Terminals

DANGER
Hazard of electric shock, explosion, or arc flash The upstream overcurrent protective device (and its settings) must be sized to ensure a disconnecting time within 0.07 seconds in case of a short circuit between the input/bypass phase and the UPS. Failure to follow these instructions will result in death or serious injury.

Compliance is assured with the recommended breaker (and its settings) from the table below.

Required 3-Pole Upstream Protection

NOTE: Ir must be set on the breakers during start-up.

Recommended Cable Sizes

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 6 mm² (10 -15 kVA UPS), 16 mm²(20 kVA UPS) , 25 mm² (30 kVA UPS), or 35 mm² (40 kVA UPS). Shrink sleeves must be fitted over the 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.

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 6 mm² (10 -15 kVA UPS), 16 mm²(20 kVA UPS) , 25 mm² (30 kVA UPS), or 35 mm² (40 kVA UPS).
Shrink sleeves must be fitted over the 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.

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 conductors
PE cable size is based on table 54.2 of IEC 60364-5-54
Installation method C
Specific to AC cables: Maximum length 70 m with a line voltage drop <3% installed on perforated cable trays, XLPE-type insulation, single layer trefoil formation, THDI between 15% and 33%.
Specific to DC cables: Maximum length 15 m with a line voltage drop <1%

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

NOTE: Recommended cable sizes and maximum allowable cable size may vary for the auxiliary products. Refer to the installation manual provided with the auxiliary product.

NOTE: The DC cable sizes given here are recommendations – Always follow the specific instructions in the battery solution documentation for DC cable sizes and DC PE cable sizes and ensure that the DC cable sizes match the battery disconnect device rating.

Load Sharing in Bypass Operation in a Parallel System

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.

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.

The impedance of the bypass paths needs 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.
