Proceed the opposite way to unmount the monitor.
Make all the connections and fix the cover of the
left part of the housing with the two screws.
NOTE. Connect wires to terminals in accordance to
VM/300.
WARNING. In installations with XA/300LR we
recommend you gather up the ID (SN) codes,
applied on the outside of the housing, and enter
them in the tables that come with the XA/300LR,
MPP/300LR and IPC/300LR.
