Repairing the TimeProvider 5000
Repairing the TimeProvider 5000 is limited to replacing modules. Refer to
With Modules, on page 67, for information on how to properly handle modules to
prevent electrostatic or physical damage.
Each power module in the TimeProvider contains a 3A fuse, but these fuses are not
field-replaceable. There are no field-serviceable fuses in the TimeProvider 5000. If a
fuse blows in a TimeProvider 5000, the unit must be returned to the factory for
repair.
