On request, the switchboard can be fitted with a relay microprocessor unit. This unit combines all the protection, control, measuring, etc. functions usually entrusted to several devices in a single piece of apparatus. The relay unit also makes it possible to dialogue with the installation control and automation systems, allowing plant data acquisition and processing. Surface treatment The units are made of pre-galvanized sheet. The doors and front panels are painted grey RAL The surface appearance is semi gloss. The standard version switchboards have their sides made of pre-galvanized sheet (on request, RAL 7035 painted versions are available). Degrees of protection IP2X inside the switchboard IP3X on the external housing. Quality Assurance system Complies with ISO 9001:2008 Standards, certified by Lloyd Register Quality Assurance Italy.

Earthingswitch Compartments The structure of each unit is entirely constructed using pre-galvanizedmetalsheets. Each unit consists of several compartments withmetalsegregations between them. Each unit is presetwithspecial holes for xing to the oor and is provided with bottom closure tted with special openings for medium voltage and auxiliary circuit cable passage. All the units ttedwitha door have an interlockwhichonly allows door opening under safe conditions. The busbarcompartment is accessed from the roof or from the front by dismantling the special metal cover. There is a special metal wiring duct in each unit to segregate the low voltage circuits from the medium voltage circuits. Busbarcompartment(A) This contains themainbusbarsystem. The busbars,madeof electrolytic copper, are xed to the terminals of the insulation isolator or of the switch-disconnector. Insulation is guaranteed in air. Feedercompartment(B) This is normally segregated fromthebusbarcompartment bymeansof an isolator or a switch-disconnector. It contains the apparatus shown in the gure below. Auxiliarycircuits A box containing all the lowvoltageapparatus normally used can be provided in front of the busbarcompartment. In particular: -terminal boxes,wiringducts and cables to connect the auxiliary circuits of the unit; -auxiliary accessories of the circuit-breaker and unit (measuring instruments, protection relays, control and signalingdevices, fuses, auxiliarycircuit protection circuit-breakers, etc.) Cable passage for inter-panel connections is made by means of special holes provided in the walls of the box itself. Installation room The installation room must be prepared according to the switch-board dimensions and version. Observance of the distances indicated guarantees a regular operation of the apparatus.

6 LOW VOLTAGE SWITCHBOARDS GENERAL The low-voltage distribution elds, which are determined according to their basic type OH-D, OH-R, C, U, SK, consists of a framework structure made of adequately dimensioned metal enclosed C-sections. Their front view and size dimensions being standardized and suited on the request and needs of the customer. Field description is given below and de ned according to their rated current, circuit breaker, switch and the number of outgoing feeders. Main characteristics of all elds are the following: The busbarsare placed in the busbarcompartment on supporting insulators in the upper side of the elds. All metal parts which are normally free of voltage are respectively galvanicallyconnected through toothed washers and are connected to the central earthingstrip passing through the elds. The surface protection is carried out by applying standard paint RAL 7035 in an up-to-date manner, thus ensuring a high degree of anti corrosion protection. The degree of protection depending both on the requirements and the conditions prevailing at the location where these elds are to be installed, may be up to IP 33. Combining these elds allows obtaining typical low-voltage distribution boards, which bear the following basic markings: -DpR-Incoming eld with circuit breaker-outgoing eld -DsR-Incoming eld with switch -outgoing eld -UDpR-Street lighting incoming eld with circuit breaker-outgoing eld -UDsR-Street lighting incoming eld with switch -outgoing eld -2Dp2RC -Two incoming elds with circuit breaker-coupling eld -two outgoing elds. -2Ds2RC -Two incoming elds with switch -coupling eld -two outgoing elds -U2Dp2RC -Two street lighting incoming elds with circuit breaker-coupling eld -two outgoing elds -U2Ds2RC -Two street lighting incoming elds with switch -coupling elds -two outgoing elds -D1pR-Incoming eld with circuit breaker-outgoing eld (inseparable) -D1sR-Incoming eld with switch -outgoing eld (inseparable) -UD1pR-Street lighting incoming eld with circuit breaker-outgoing eld (inseparable) -UD1sR-Street lighting incoming eld with switch -outgoing elds (inseparable)
