INSTALLATIONS
A clean, flat surface capable of supporting the Package Compact Substation unit weight is the
only requirement for a foundation. It is, however, important that adequate accessibility,
ventilation and ease of inspection of the unit must be provided.
In all installation work, the safety regulations for electrical installations have to be observed.
CONNECTIONS
Each Package Compact Substation must be permanently grounded or earthed by connecting an
affective recognised ground or earth as prescribed by the latest applicable edition of IEC or
ANSI requirements.
The Package Compact Substation is designed to operate with a solidly grounded neutral system.
The neutral connection should be solidly and permanently grounded.
