Function:

The LLE -P series are used for the standard illumination while LLEE -P series are proposed with function “normal + emergency” in order to grant a sufficient illumination to leave the area in case of temporary black-out. The wiring diagram of LLEE -P series is designed to provide a continuous power supply to the emergency unit to grant its full functionality anytime. Besides a LED unit, well visible from outside, indicates the status of emergency unit through green/yellow/red colours to facilitate the maintenance activity. The internal wiring is designed to allow any combination of loop-in loop-out installation. The light fitting can be installed using different mounting types as descri bed in dedicated section of this catalogue.

Construction:

The materials used to manufacture the LLE / LLEE -P series have been studied to grant the maximum protection against the highly corrosive agents present in these industries:

• the body in glass fiber reinforced polyester (GRP), provides a very high mechanical strength together with a good resistance against the UV ray effects;

• the transparent diffuser in UV ray resistance polycarbonate has a self-extinguishing property according to Standard UL 94;

• the gasket on cover grants an IP66 protection level ;

• the closing system in one single spot, apart from facilitating greatly the maintenance operations, is itself a guarantee of first-rate holding system since it provides a constant pressure of seals over all the perimeter of the diffuser ;

• the internal electrical components are fully sealed to prevent any corrosive action that could cause electrical faults;

• the body has two cable entries M25x1.5 on one side and one cable entry M25x1.5 on the opposite side so to allow any loop-in loop-out installation. On request it’s possible to have two cable entries M25x1.5 on both sides;

• all the light fittings are equipped, as standard, with one cable gland and two stopping plugs in polyamide, Atex/IECEx certified. Other materials or combinations are available as option;

• the LED modules are fixed on internal frame and are available with or without diffuser; the diffuser is anyway available as option;

• electronic ballast, equipped with some self-protective functions, works with a multirange voltage and has a two-supply circuit design so to continue to energize one LED module in case the second one is faulty;

• internal circuit is protected by fuses so to minimize any possible problems caused by over-voltage during normal operation.
