24 Volt DC ONLY
CAUTION:
Please observe cable voltage drop
Please observe cable voltage drop. Distance between the applied DC transformer and the ICAD terminal box may
cause a voltage drop. Cross section of cables and size of DC transformer must be calculated so that the voltage at
all time at the ICAD terminal box
(1)
, both during standstill and during operation of ICAD, is within this range:

Data communication
RS-485: It is important that the installation of the data communication cable is done correctly. Remember
termination at the bus termination. Max length of cable: 1200 m with specic cable and limited data rate. Follow
RS-485 standard.
Insulation from power supply input, metallic part and interface output: 500 V DC: For input/output connections.
