Safety Instructions:
Before installation read these instructions carefully and
completely. This installation instruction cannot account for
every possible condition of installation, operation or
maintenance. Further information can be obtained from
your local distributor’s office or from the product data sheet,
which can be downloaded, from the Internet
at www.tracopower.com/products/txh.pdf
Before any installation, maintenance or modification work
ensure that the main switch is switched off and prevent ed
from being switched on a gain. Non-observance, touching
of any live components or improper handling of this power
supply can result in death, severe personal injury or
substantial property damage. Proper and safe operation is
dependent on proper storage, handling, installation and
operation.
Compliance with the relevant national regulations must be
ensured. Before operation is started the following conditions must be ensured:
Connection to mains supply in compliance with national
regulations (VDE0100 and EN50178).
By use of stranded wires, all strands must be fastened
in the terminal blocks. (Potential danger of contact with
the case)
Power supply and mains cables must be suff iciently
fused.
All output wires must be rated for the power supply
output current and must be connected with the correct
polarity.
Sufficient cooling must be ensured.
Never work on the power supply if power is supplied!
Risk of electric arcs and electrical shock, which can cause
death, severe personal injury or substantial property
damage.
.
Installation Instructions:
This power supply is designed for professional indoor
systems. In operation the power supply must not be
accessible. It may be installed and put into service by
qualified personnel only.
The correct mounting position for optimal cooling
performance must be observed. Do not cover any
ventilation holes. Leave a free space of minimum 50mm
(2in.) above and on the sides of the power supply. Observe
power derating. (see our data sheet)
Do not operate without PE connection! To comply with
EMC and safety standards (CE mark, approvals) the
power supply must be operated only if PE terminal is
connected to the non-fused earth conductor.
While putting on connectors or wires, no mechanical stress
should be applied to the printed circuit board and its
components.
The internal fuse(s) may not be replaced by the user. If an
internal fuse has blown, the power supply has an internal
defect and, for safety reasons, must be shipped to your local distributor .
Note: This unit contains an automatic inp ut voltage
selection switch. Do not change the input voltage without
disconnecting the input connector.
Recycling: The unit contains elements that are suitable for
recycling, and components that need special disposal. You
are therefore requested to make sure that the power
supply will be recycled env ir on ment frie ndly at the end of
its service life.
Warning: Hazardous voltages and components storing a
very substantial amount of energy are present in this
power supply during normal operating conditions. However,
these are inaccessible. Improper handling may result in an
electric shock or serious burns!
Do not open the power supply.
Do not introduce any objects into the power supply. An
output voltage adjustment potentiometer may only be
actuated using an insulated screw driv er.
Keep away from fire, water and chemicals.
