power supply panel.
2. Allow the lamphead fan to complete its cooling cycle. If this has been
prevented by premature isolation of the control cabinet, always allow
sufficient time for the bulb to cool before proceeding.
3. Turn off the main electrical disconnect. Follow all relevant OSHA
established lockout procedures or local codes as appropriate.
