Safety

Replacement:
This part 2-2 of IEC 61558 applies to stationary or portable, single-phase or poly-phases, aircooled control transformers associated or otherwise having a rated supply voltage not exceeding 1 000 V a.c. or 1 415 V ripple free d.c. and rated frequency not exceeding 500 Hz and no limitation of the rated output.
This standard is applicable to transformers used between circuits where double or reinforced insulation is not required by the installation rules or by the equipment specification.

Replacement:
This part 2 of IEC 61558 applies to stationary or portable, single-phase or polyphase, air-cooled isolating transformers, associated or otherwise, having a rated supply voltage not exceeding 1000 V a.c. and rated frequency not exceeding 500 Hz, the rated output not exceeding: - 25 kVA for single-phase transformers; - 40 kVA for polyphase transformers.

Replacement:
This part 2 of IEC 61558 applies to stationary or portable, single-phase or polyphase, aircooled safety isolating transformers, associated or otherwise, having a rated supply voltage not exceeding 1000 V a.c. and rated frequency not exceeding 500 Hz, the rated output not exceeding: - 10 kVA for single-phase transformers; - 16 kVA for polyphase transformers.

This is the harmonized CSA Group and UL standard for General Requirements for Battery-Powered Appliances. It is the first edition of CSA C22.2 No. 0.23, and the second edition of UL 2595. This edition of UL 2595 supersedes the previous edition published on May 22, 2013.
Scope:

This part of IEC 60896 applies to all stationary lead-acid cells and monobloc batteries of the valve regulated type for float charge applications, (i.e. permanently connected to a load and to a d.c. power supply), in a static location (i.e. not generally intended to be moved from place to place) and incorporated into stationary equipment or installed in battery rooms for use in telecom, uninterruptible power supply (UPS), utility switching, emergency power or similar applications.

Abstract: Part 2 sets out recommended practices for the installation, maintenance, testing and replacement of sealed secondary batteries permanently installed in buildings.
Scope:

Abstract: Specifies requirements for the installation of vented secondary batteries permanently installed in buildings.
Scope:

In recent years, there has been a marked increase in the deployment of lithium ion batteries in energy storage systems (ESS). Many ESS are being deployed in urban areas both in high rise structures and single- and multi-family residences. Local Authorities Having Jurisdiction (AHJs) along with the ESS integrators and installers are challenged by the lack of clear direction on fire protection and suppression in these installations.

Scope

1.1.1
This Model Code provides marking and test/construction requirements for the field evaluation of electrical equipment by an inspection body, where certification of that equipment is impracticable or otherwise unavailable.

1.1.2
Field-evaluated equipment found to be in conformity with the requirements of this Model Code is considered to be acceptable to the AHJ.

1.1.3

1 Scope
1.1 These requirements apply to controls that employ solid-state devices and are intended for specified safety-related protective functions.
