EN 50288-7 Cables
APPLICATION

EN 50228-7 cables are used for transmission of analogue and digital signals in instrument and control systems; allowed for use in zone 1 and zone 2, group II, classified areas (IEC 79-14), not allowed for direct connection to low impedance sources, e.g. public mains electricity supply.
Recommended for indoor and outerdoor installation, on racks, trays, in conduits, in dry and wet
locations; not for direct buiral.
Recommended for use as fire protection messure for people and important material assets.

STANDARDS Basic design to EN 50288-7
