Periodic System Maintenance
Perform Periodic Maintenance every six (6) to twelve (12) months, depending on
the environmental conditions.
A. Turn power to the dimmer pack OFF.
B. Remove Ramp Cards and Power Supply Card from the Motherboard,
dust them off with a soft natural bristle brush, and clean their edge con-
nectors with a mixture of 70% denatured alcohol and 30% distilled water
(or other cleaning compound intended for gold edge connectors).
C. Inspect the dimmer pack for loose connections, build-up of dust, and
(for permanent or semi-permanent installations) placement of obstruc-
tions around it which may impede air flow. Tighten any loose connec-
tions found at this time.
D. Vacuum out any excessive dust build-up in the dimmer pack while
power to the pack is shut down.
D. Exercise all circuit breakers by turning them ON and OFF several times.
E. Replace Power Supply Cards and Ramp Cards.

ages and adjust as required.
