NECA 411:2014 PDF Download

The NECA 411:2014 standard provides guidelines for the installation and maintenance of Uninterruptible Power Supplies (UPS) in commercial and industrial settings. This standard specifically focuses on UPS units that are rated at 30 kVA (kilovolt-ampere) or higher and operate at voltages of 600 Volts or less.

The standard covers both the installation and maintenance procedures for static three-phase UPSs, which are solid-state power systems that provide continuous regulated AC power. These UPSs can operate from either an AC power source or a battery system. Additionally, the standard also includes guidelines for the installation of related battery systems that are connected to the UPS.

The standard applies to both indoor and outdoor installations and is intended to ensure safe and efficient operation of UPS units in commercial and industrial applications.
