Requirements
– Power supply: 15 VDC - 26 VDC
– WS station without camera or TFT-display
– Flush Mount Kit (WSFB 50x) or Surface Mount Kit (WSSH 50x)
Mounting instructions / Restrictions
– Do not expose the station to extreme temperature.
– Observe the country specific standards for installation, mounting and
configuration.
– When opening the stations ESD precautions must be observed.
– The housing may only be opened by authorised service engineers.
– Induction Loop Performance compliant with IEC 60118-4 (when correctly
installed)
– Metal Structures significantly affects performance of the induction loop
system. The magnetic field generated by an induction loop system,
induces a current in any closed path of a metal structure placed in the
vicinity of the induction loop. These induced currents tend to weaken the
magnetic field and cause loss.
Examples of metal structures:
– Lightweight floor construction with a (usually profiled) metal sheet
under a thin reinforced concrete slab.
– Girders, beams, constructional metal work
– Metal cladding and walls
– Metal box construction (elevators, lifts)
