Omega Vehicle Security OMB-DBK-34A Manuel D’Utilisation

 

•  The operator must observe all safety cautions and operating conditions specified in the 

documentation for all hardware used. 

•  The host computer and all connected equipment must be CE compliant. 
•  All power must be off to the device and externally connected equipment before internal access to 

the device is permitted. 

•  Isolation voltage ratings:  do not exceed documented voltage limits for power and signal inputs. 

All wire insulation and terminal blocks in the system must be rated for the isolation voltage in use.  
Voltages above 30 Vrms or ±60 VDC must not be applied if any condensation has formed on the 
device. 

•  Current and power use must not exceed specifications.  Do not defeat fuses or other over-current 

protection. 

 

The specific immunity conditions for CE compliance vary by product; but general immunity conditions 
include: 

•  Cables must be shielded, braid-type with metal-shelled connectors.  Input terminal connections are 

to be made with shielded wire.  The shield should be connected to the chassis ground with the 
hardware provided. 

•  The host computer must be properly grounded. 
•  In low-level analog applications, some inaccuracy is to be expected when I/O leads are exposed to 

RF fields or transients over 3 or 10 V/m as noted on the Declaration of Conformity. 

 

This section of describes three CE enhancements. 

•  DBK41/CE 
•  Edge Guards for the DBK5, DBK8, and DBK44 
•  BNC Connectors for CE compliance 

A plastic barrier attached to the end of a DBK card helps prevent access to leads, and to live circuits. 
The edge guards attach to DBKs (see figure below) that are mounted in a DBK41/CE, with EMI shield 
plates.  The access slot allows insulated wires to pass through the barrier.
