Warnings overleaf.
CAUTION: Risk of Danger
Read complete instructions prior to installation and
operation of the unit
CAUTION: Risk of electric shock
Intended Use: The APM has been specifically designed for engineers requiring an effective way to monitor and
display data. The APM accepts a range of electrical inputs (depending on the model) and displays the data on its
integrated multi-format display. The APM has been designed for industrial use only, by installation into electrical
cabinets or display panels.
