6. Maintenance
6.1. General
Read and observe the notices in chapter 1.2 Health and Safety.
Caution: Rotating fans. Risk of injury in operation. Wear tight-fitting clothes and
disconnect mains before connecting or replacing or cleaning the fan unit.
Caution: The unit reaches high temperature in operation. Risk of burns by hot
surface. Do not touch the unit before it has sufficiently cooled down.
F Note: The Remote Unit does not require preventative maintenance measures.
F Note: We recommend checking the cleanliness of the unit and in particular of
the heat sink / fan(s) at appropriate intervals depending on the degree of
dust and dirt at the installation site. If necessary, any dusty or dirty areas /
parts should be cleaned at regular intervals, which also depend on the
degree of dust and dirt at the installation site.
Maintenance of the ION-U High Power RUs should be performed by replacing only
components that are described in this chapter. In order to maintain the warranty,
avoid unintentional damage to the seals on the modules.
The spare parts list, (see chapter 7.3) includes only units that can be replaced in the
field without tuning or soldering work.
F Note: When sending back the unit, use appropriate packaging. Use of the
original packaging for shipping the unit is strongly recommended.
F Note: Defective parts should only be replaced by original parts from the
supplier. All service work performed inside the housing is performed at
the users own risk.
F Note: Ensure the Remote Unit has been disconnected from mains power
during maintenance.
F Note: Label any unlabelled cables before disconnecting them to ensure
correct reconnection.
For most maintenance procedures, appropriate tools are required to ensure correct
handling. All of these tools can be ordered from the supplier.
F Note: All Remote Unit screws have a right-hand thread, and are tightened by
turning the screws clockwise and loosened by turning them counter-
clockwise with an appropriate tool.
Due to the design of the Remote Unit, the fan unit is the only component that should
be replaced in the field. Please contact the supplier for replacement of any other
components.
