    Full text manual (for reference)

    Installation instructions for the Video Mount Products (VMP) ER-184-4PKIT — a rack expansion kit that extends an ER-184 equipment rack by 4U of additional rack space.

    Overview

    The ER-184-4PKIT is an add-on kit designed to connect to an already-assembled VMP ER-184 equipment rack, extending its usable rack height. The kit uses connector plates and "L" support brackets to join the new section to the existing rack frame.

    Safety Warning

    The installer of this rack must verify that the equipment placed within does not exceed the load rating for the rack. Video Mount Products will not be held liable for improper use or installation of its products.

    Installation Steps

    1. Before starting, lay out all parts and match them to the parts list provided. Verify you have all parts before beginning assembly. Note: the ER-184 base rack must already be assembled before installing the ER-184-4PKIT.
    2. Attach the connector plates (#10) to support plate A (#4A) using the ¼"–20 UNC screws (#7).
    3. Connect support plate A (#4A) to the left and right "L" supports (#2A and #2B). First line up the rearmost hole and insert the screw (#7). Then grab the support plate and slightly twist it until the foremost holes line up with the holes in the "L" supports.
    4. Attach the middle connector plates (#11) to the left and right "L" supports (#2A and #2B) using the ¼"–20 screws and nuts (#7 and #8).
    5. Connect the ER-184-4PKIT to the ER-184: first remove the four screws on the rear of the support plate (#4B). Using those screws plus the remaining ¼"–20 screws and nuts (#7 and #8), attach the connector plates (#10) to support plate (#4B), the middle connector plates (#11) to the left and right supports (#1A and #1B), and the left and right "L" supports (#2A and #2B) to the back of the base plate (#3).
