TRANSMITTER HEAD 3300 SERIES
The Entity concept allows interconnection of intrinsically safeapparatus to associated apparatus not
specifically examined in combination as a system. The approved values of max. open circuit voltage (Uo)
and max. short circuit current (Io) and max. power (Uo x Io / 4), for the associated apparatus must be less
than or equal to the maximum safe input voltage (Ui), maximum safe input current (Ii), and maximum safe
input power (Pi) of the intrinsically safe apparatus.In addition, the approved max. allowable connected
capacitance (Co) of the associated apparatus must be greater thanthe sum of the interconnecting cable
capacitance and the unprotected internal capacitance (Ci) of the intrinsically safeapparatus, and the the
approved max. allowable connected inductance (Lo) of the associated apparatus must be greater than
the sum of the interconnecting cable inductance and the unprotected internal inductance (Li) of the
intrinsically safe apparatus.
