5. Maintenance
5.1. General
Read and observe 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.
Due to the design of the Extension Unit the only component recommended to be
replaced is the fan unit. The spare parts list, consequently, contains only units which
can be replaced without tuning or soldering work. For replacing any other
component, please contact the supplier.
Take care not to unintentionally damage any seals to maintain warranty. Please keep
these guidelines in mind during maintenance:
 Note: The Extension Unit does not require preventative maintenance measures.
 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.
 Note: Ensure the Extension Unit has been disconnected from mains power
during maintenance.
 Note: When sending back the unit, use appropriate packaging (see also section
6.2.2 Mechanical Specifications for details). Use of the original packaging
for shipping the unit is strongly recommended.
 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.
 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.
 Note: All Extension 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.
