General Installation Instructions
Please consider besides these general instructions also any product-specific instructions in the
"Installation" chapter of this manual.
Unpacking
Check the equipment for any transport damage. If the unit is mechanically damaged, if liquids
have been spilled or if objects have fallen into the unit, it must not be connected to the AC
power outlet, or it must be immediately disconnected by unplugging the power cable. Repair
must only be performed by trained personnel in accordance with the applicable regulations.
Installation Site
Install the unit in a place where the following conditions are met:
The temperature and the relative humidity of the environment must be within the
specified limits during operation of the unit. Relevant values are the ones at the air
inlets of the unit.
Condensation must be avoided. If the unit is installed in a location with large
variation of ambient temperature (e.g. in an OB-van), appropriate precautions must
be taken before and after operation.
Unobstructed air flow is essential for proper operation. Air vents of the unit are a
functional part of the design and must not be blocked in any way during operation
(e.g. by objects placed upon them, placement of the unit on a soft surface, or
installation of the unit within a rack or piece of furniture).
The unit must not be heated up by external sources of heat radiation
(sunlight, spot lights).
Ambient Temperature
Units and systems by LightViper are generally designed for an ambient temperature range (i.e.
temperature of the incoming air) of +5...+40 °C. When rack mounting the units, the following
facts must be considered:
The admissible ambient temperature range for operation of the semiconductor
components is 0 °C to +70 °C (commercial temperature range for operation).
The air flow through the installation must provide that the outgoing air is always
cooler than 70 °C.
Average heat increase of the cooling air shall be about 20 K, allowing for an
additional maximum 10 K increase at the hot components.
In order to dissipate 1 kW with this admissible average heat increase, an air flow of
2.65 m_/min is required.
Example: A rack dissipating P = 800 W requires an air flow of 0.8 * 2.65 m_/min which
corresponds to 2.12 m_/min.
If the cooling function of the installation must be monitored (e.g. for fan failure or
illumination with spot lamps), the outgoing air temperature must be measured
directly above the modules at several places within
