Temporary Component Storage
During installation, it is recommended that you designate a secure temporary storage area for the components that you remove from the enclosure. LCL filter modules and power modules present a tip-over hazard when removed from the enclosure. Measures must be taken to be sure that modules are stored in such a way that they do not pose a hazard.
Do not store components in active isles or work areas. A dedicated area that is designated for the temporary storage of the components that are removed during the installation process is recommended. Loose components can be hazardous and easily damaged.
