PS-1120 POWER SUPPLY OPERATION MANUAL
6.0 MAINTENANCE
6.1 REPAIRS
The PS-1120 Power Supply is, generally speaking, a trouble-free unit. No
routine maintenance or repair is required.
The power supply is protected by a 7A slo-blow fuse in one leg of the DC input.
If this fuse opens, do not replace it. Return the unit to the factory for repair.
In the event that the unit fails or does not function properly, it is strongly
suggested that no attempt be made to troubleshoot. Field repairs or customer
modifications are not authorized, and, if attempted, will void the warranty.
Repairs must be made only by factory-trained personnel.
6.2
REPACKING AND STORAGE
If the PS-1120 is to be stored for a prolonged period, shipped to another location,
or returned to the factory for repair, it should be repacked in the original
packaging material. If the packaging material has been discarded, the unit
should be packaged in a suitable container with sufficient protective material to
ensure that the unit cannot move within the package and is protected from
damage that could occur from improper handling.
Any storage area used for the unit should be dry, at a temperature of -40
°
F to
+194
°
F (-40
°
C to +90
°
C).
WARNING!
The PS-1120 output voltage MUST be limited to match the
specifications of those components to which it is
connected. Exposing any system component to voltage (or
any other operating condition) that exceeds its rating can
result in damage to the unit and personal injury.
