IEC 62109-1 Safety of power converters for use in photovoltaic power systems – Part 1: General requirements

This Part of IEC 62109 specifies the safety requirements that are generally applicable to all equipment within its scope. For certain types of equipment, these requirements will be supplemented or modified by the special requirements of one or more subsequent parts (for example IEC 62109-2, IEC 62109-3, etc.) of the standard which must be read in conjunction with the Part 1 requirements.

For the purposes of this document, the fllowing terms and definitions apply.
NOTE Unless otherwise specified, values of “voltage” and “current” are the r.m.s. values of an alternating, direct
or composite voltage or current.

accessible
able to be touched with the standard access probes when used as specified in 7.3.4

basic insulation
insulation which provides a single level of protection against electric shock under fault-freeconditions
NOTE Basic insulation may serve also for functional purposs.

battery type
the battery chemistry (e.g. lead-acid) and type (e.g. flooded, gel, etc.) or types of batteries intended for use with the PCE

battery . sealed
a battery with no provision for the addition of water or electrolyte, and constructed so as to prevent the emission of liquid or gasses under normal operation
battery = non-sealed
a battery with removable caps or other provision for addition of water and/or electrolyte
