• Once a unit is removed from service, vacuum all air vents, including the front panel
grill.
• Clean the exterior with a mild solution of detergent and water. Apply the solution onto
a soft cloth, not directly to the surface of the unit. To prevent damage to materials, do
not use aromatic hydrocarbons or chlorinated solvents for cleaning.
• Check external connections for integrity of insulation, loose contacts, and proper
torque.
• If there is any evidence of short-circuits or arcing, overheating, or corrosion, contact
the factory for recommended service.
5.3 Fuses
There are no user replaceable components in the power supply. Internal fuses are listed
in Table 5–1. Fuses are sized for fault isolation, and, an open fuse might indicate that a
circuit component has been damaged. Contact the factory for further assistance.
CAUTION!
To reduce the risk of fire or electrical shock, replace fuses only
with the same type and rating.
