Upstream and Downstream Protection - Easy UPS 3S Pro 380/400/415 V

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. The battery disconnect devices 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 circuit breaker (and its settings) from the table below.

Required 3-Pole Upstream Protection

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