ITVC Power cables: max. 10mm²
Signal cables: max. 2,5mm² (Use of shielded cables is recommended, especially for analogue signals)
Earthing and protective conductors:

Insert the connection cables into the electrical enclosures through the cable glands (or conduits) and connect the
electrical supply and the control signals to the ITVC terminal blocks, according to the Wiring Diagram. Screw the cable
glands (or the conduits) tightly into the threaded entries, in order to guarantee the weatherproof and explosion-proof
protection (when applicable). Thread sealant is necessary for explosion proof capability. Replace the plastic plugs of the
unused
enclosure entries by metal ones, to guarantee perfect weatherproof tightness and to comply with the explosion-
proof protection codes (where applicable).
11.3 Weights and Measurements
Ferrite bead
Assemble the ferrite bead/s
provided by DVG with
documentation package, onto
the digital control cable/s
Grounding must be done according to statutory requirements.
Connect the internal ground lead/s to the bus bar/s
Connect external ground lead to external ground connection
To avoid electromagnetic interference due to electrical cables coupling use separated
cables for power and signals. Use shielded cables for analogue and data signals

without battery is 17 Kg / with battery 19 Kg.
Total weight of the ITVC,
SS 316L (cast CF3M) enclosure, without battery is 46.5 Kg
/ with battery 50 Kg.
See Annex C and E for weight and measurement of ITVC
