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 disconnect devices are sized based on the nominal current +10%. This is to accommodate either low grid voltage or deviation in length between parallel UPSs.

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 circuit breaker (and its settings) from the table below.

Required 3-Pole Upstream Protection

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.
