VERSIONS

The SCAME range of distribution assemblies includes the following Series: - MEGA - MASTERBOX - DOMINO - BLOCK - GOMMA SCAME's distribution assemblies are available in the following versions: - Fully pre-wired units: standard equipment for industrial and similar applications, construction sites, etc. - Partly pre-wired units: equipment partly factory-wired at SCAME, to be completed by the user. - Empty units with plain front panel: which can house any type of industrial and/or domestic sockets, protective devices and other types of compatible low-voltage electrical equipment (this version is not available for MEGA units). - Empty units with front-panel cut-outs: designed to house industrial 16 A and 32 A IEC309 or EUREKA Series socket outlets, 10 A and 16 A domestic European type socket outlets (to CEI, VDE, UTE and BS) and 16 A and 32 A OMNIA interlocked-switch socket outlets (only for DOMINO units) NOTE: This version is available only in DOMINO and BLOCK Series.

PRE-ASSEMBLIES

Pre-assemblies are ready-made distribution assemblies, fully pre-wired and equipped with industrial and/or domestic sockets, protective devices (modular or moulded-case MCBs and RCDs) and accessories. SCAME also offer a partly wired version (up to the EN50022 rail), equipped with industrial and/or domestic sockets, but without protective devices. The choice, purchase and installation of these articles is left to the customer. Pre-assemblies constructed and wired in-house by SCAME undergo strict quality control to pass all tests required by the standards. This assures the safety, reliability and long life of the equipment, provided the user operates correct installation, practices in accordance with the relevant wiring regulations. The following pages describe many of the standard assemblies produced by SCAME, which differ from each other by version, socket combination, protective devices and protection degree. Together they will meet most of the installation requirements that arise in terminal power distribution.

CUSTOMISED ASSEMBLIES

Consistent with their strongly customer-oriented marketing policy, SCAME also offer distribution assemblies housing combinations of sockets and protection devices made up to specific customer requirements. SCAME are in a position to design, implement and supply to order, accurately finished distribution assemblies at short notice. For any enquires in connection with customised distribution assemblies, please contact SCAME UK.

COMPLIANCE WITH STANDARDS

All SCAME's empty units are constructed to meet IEC 670 requirements. The assemblies comply with EN 60439-1 (IEC 60439-1) and EN 60439-4 (IEC 60439-4) standards.

ACCESSORIES

SCAME supply a kit containing several standard installation accessories together with every empty unit. Other optional accessories are available on request.

DOUBLE INSULATION

All SCAME's thermoplastic units are provided with double insulation. This ensures safety in use since it prevents live parts from coming in contact with the outside of the enclosure in the event of a malfunction.

PRACTICAL ADVICE

Read and follow the instructions carefully. All regulations in force governing electrical installations must be observed: Check the assemblies regularly and replace them as soon as they show evident signs of wear and tear. Always employ qualified technical staff. If the product has been subject to impact or knocks, it should be checked at once even if it has suffered no evident damage. Never enclose the assembly in such a way as to hinder inspection and/or maintenance. Always employ qualified technical staff for any work on the switchgear. If any switchgear has been subject to impact, it should be checked at once even if it has suffered no evident damage.

DISTRIBUTION ASSEMBLIES

COMPLIANCE WITH DISTRIBUTION ASSEMBLIES STANDARDS

Distribution assemblies must comply with the standards listed below:

EUROPEAN STANDARD EN 60439-4 (IEC 439-4)

Distribution assemblies for use on construction sites. In conformity with the requirements of international regulations, distribution assemblies used on construction sites must comply with standard EN 60439-4 "Particular requirements for assemblies for construction sites (ACS)" , which supplement, amend and supersede some articles of standard IEC 439-1. Therefore all assemblies for construction sites (ACS) must take into account both the general standard EN 60439-1 and the specific standard for construction sites EN 60439-4. In particular, standard EN 60439-4 requires that: - the maximum rated voltage does not exceed 1000 V (a.c.) and 1500 V d.c.; - all ACS distribution assemblies bear one or more permanently inscribed data plates which are clearly visible after installation; - the data plates carry the following information: · manufacturer's name or trade-mark · designation of the type and identification number which allow the user to apply to the manufacturer to obtain additional technical information; · reference to standard EN 60439-4; · rated current, type of current and, if a.c, frequency.

European standard EN 60439-1

Distribution assemblies to be used in industrial, agricultural, service industry etc., applications in regular and heavy duty conditions. This standard requires: - that mass-produced distribution assemblies (TTA) are subject to type testing, and - that non-mass produced distribution assemblies (PTTA) are partly subject to type testing. All SCAME distribution assemblies (pre-wired unit fully equipped with sockets, protective devices, etc.) comply with IEC 60439-1. Since they are mass-produced (TTA), they are subject to type testing, an additional assurance for the user.

FINAL DISTRIBUTION ACS

Masterbox Series distribution assembly data plate

Compliance of ACS assemblies to EN 60439-4 is tested by type tests on a sample constructed according to the manufacturer's prescribed production system or without modifications from it such as to affect the performance.

DOCUMENTATION FOR ACS

The manufacturer must specify in their documentation all conditions of installation, operation and maintenance of the assemblies and of the equipment housed in them. If the wiring diagram is not evident, suitable additional information must be supplied, eg. circuit diagrams or tables of connections. The manufacturer must also issue a conformity declaration certifying that the product has been produced in compliance with the standards.

FLEXIBLE USE

An outstanding feature of SCAME's range of distribution assemblies is their highly flexible use due to: - the considerable number of different possible combinations of industrial and/or domestic socket outlets which can be mounted in the assemblies; - the numerous possibilities of stationary and mobile installation: surface mounting, flush mounting, turret mounting, self-supporting, portable and on a wheeled cable-reel stand.

ACS SCAME

SCAME ACS assemblies are available for the functions listed below. Their specifications comply with those prescribed by the standards: Distribution ACS consisting of one inlet unit and several outlet units. - rated current between 125 A and 630 A - outgoing feeder cables connected to terminals or sockets - isolating device that can be padlocked in OFF position. Final distribution ACS consisting of one or more outgoing feeders - Max. rated current 125 A - isolating device can be padlocked in OFF position - no provision for delaying the tripping time of the protective devices - residual current device (RCD) with I dn < 30mA as additional protection against indirect contacts - max. 6 sockets protected by each RCD. Socket-outlet ACS mobile or portable - Max. rated current 63A - incoming cable connection either to appliance inlet or to connecting device - outgoing cables connected only to socket outlets - each socket outlet to be provided with its own overload protection. In addition, all socket outlets (max. 6) to be protected against indirect contacts by means of RCD with I dn > 30 mA. SCAME's factory-assembled MEGA, MASTERBOX and portable DOMINO and BLOCK Series assemblies have been designed and constructed for use on construction sites. These assemblies therefore comply with EN 60439-1 and EN 60439-4; in particular, they meet Standard requirements for the following uses: - MEGA assemblies: distribution ACS - MASTERBOX assemblies: final distribution ACS - DOMINO and BLOCK portable assemblies: socket outlet ACS NOTE: Two or more functions as described above may be combined in a single ACS assembly, eg. a socket outlet ACS may be combined with a transformer ACS. Compliance with the European Standard 60439-4 for assemblies for construction sites (ACS) will be mandatory in all CENELEC member countries.
