Warning
! Do not use switching power supplies near Smart Relays. All mains adaptors 
are to be provided by the customer; they cannot be acquired from SimonsVoss. 
3.4  YOU NEED TO DETERMINE THE INSTALLATION LOCATION 
The transponder transmission range for Smart Relay (read range) is a max. of 1.5 m, 
but may be reduced in metallic environments, particularly in magnetic fields or where 
there is aluminium. 
Ideally, you should perform a read range test with an authorised transponder and a 
battery-operated Smart Relay. 
3.5 FURTHER INFORMATION 
-  All cabling used to connect Smart Relay should be type IY(ST)Y ....x0.6 - 
twisted pair, shielded cable - and cables should not exceed 100 m in length. 
Power losses should be taken into account when dimensioning the power 
supply. 
-  The technical data regarding inputs and outputs are to be taken into account 
(see Technical Data). 
-  All cabling must be installed and connected as per VDE regulations (VDE = 
German Association of Electro-technology, Electronics & Information Technol-
ogy). 
4.0  Before installation 
  Unpack Smart Relay and check for any damage. 
  Connect Smart Relay to a power supply or a battery. 
  If Smart Relay is to be operated via a mains adapter, insert the backup battery 
in the designated holder (see Installation of backup battery). 
  Check that Smart Relay functions with a transponder in its as-delivered condi-
tion. 
  Remove the housing if you install in a flush-fitted masonry box. 
  If mounted on the surface, the base plate can be used as a template for the 
drill holes (6 mm).
