Cable grommets and glands
The underside of the Compass cabinet has various types of cable grommets with cable glands. The
cable glands are intended for various types of cabling. Always use a cable grommet and gland that
is associated with a cable type with the specified cable diameter.
Always close a cable gland with a supplied dummy plug if a cable grommet is not being used.
