The Device Panel, MP-3000 and DP-4000 all fit in this same size low
voltage door cutout. The low voltage control panel is behind the low
voltage door and is completely isolated from the medium voltage
compartment. A standard viewing window allows visual verification
of the isolation switch status before attempting to open the medium
voltage door. The medium voltage door is locked closed whenever
the isolation switch is closed.
