Display Functionality
The location should provide adequate airflow around the UPM. Pro-
vide a minimum 3” clearance on all sides for proper ventilation.
Applying Power to the UPM
Connect the power cord to a verified grounded 3 wire receptacle. Verify
that the Site Wiring Fault “SF” is off (120 VAC models only). Once properly
connected and initially checked, turn on the UPM by pressing and holding the
front panel On/Off switch for 3 seconds.
