on the lower inside rear portion of the pedestal unit. Secure the top of the UB1 using the
wing nut placed on the carriage bolt installed on the PED near the top of the enclosure.
Carefully slide the MTA downward on the Universal Bracket. The slot in the top of the
MTA fi ts over the tab on the UB1.
Tighten the captive screw to secure the MTA to the lower portion of the universal bracket
assembly.
