Mounting conditions
During operation the permissible ambient temperature as stated in the must not be
exceeded. If the unit is exposed to direct solar radiation ensure that the total temperature will
not exceed the maximum permitted temperature. If these conditions cannot be fulfilled the
SITRANS SL must be installed in a cabinet with a controlled environment.
CAUTION
Avoid condensation
As condensation is normally a problem when moving the device from outdoor to the inside
of a building, the device should be adapted to the new ambient conditions for a couple of
hours before starting it.
NOTICE
The front (lid) side of the units must be accessible. To facilitate maintenance and service
there shall be at least 60 cm of free space in front of SITRANS SL transmitter and receiver
respectively. To meet the safety requirements for air convection and cooling there must be
a free space of at least 10 cm around the SITRANS SL.
Supply voltage
When the supply voltage is interrupted for more than 20 ms the unit performs an automatic
restart. 120 sec after the restart the unit works properly again.
With a slow rise of supply voltage the unit may stop working. A manual restart may be
necessary.
