PROTECTA LED (IND)
Warning:
Luminaires are assessed and/or tested for EMC requirements. This is based on the disposition
of entry cables and, where appropriate, through wiring arrangements as supplied or specified.
Users must take care not to introduce wiring into parts of the apparatus materially different to that
which could be reasonably inferred from the disposition of fixed supply terminals and specified wiring.
3.4 Light Emitting Diodes (LED)
LED’s are supplied in either 02L, 04L or 07L options with the colour temperature of 4000K or 5000K.
3.5 Mounting
Luminaires should be installed where access for maintenance is practical and in accordance with any lighting
design information provided for the installation. The standard suspension is via two M8 tapped holes in brass
bushes in the top of the body, the recommended torque for the fixing bolts is 10-15Nm. (at 400mm centres for
02L and 04L and 700mm centres for the 07L model). The brass bushes and lock nuts should not be removed
during installation. Various adaptors, pole clamps and suspension brackets are available to order. The 02L and
04L models are available with integral side entry for 42 mm diameter poles (non- emergency only).
3.6 Cable Connection
3.6.1 Cables
The temperature conditions of the supply cable entry point are such that 70ºC (ordinary PVC) cable can be used.
300/500V cable ratings are adequate and no special internal construction is necessary. Where MCB's are used,
the type with the higher short time tripping current ratio used for motor starting and lighting should be specified.
The standard maximum looping size is 2.5mm² with options of 4mm² through wiring
3.6.2 Cable Glands
Cable glands when installed should maintain the desired IP rating of the enclosure.
3.7 Electrical Connections
Luminaires are available for looping and through wiring. The through rating is 16A. Terminals for 4mm² and
6mm² are available. State which on order. If work is to be done on any Luminaire which has already been
connected to the electrical system, it must be isolated from the system. The diffuser cover is swung down and
removed if convenient by swivelling back as far as possible and the reflector tray is then slid out after releasing
the locking screws. This gives access to the mains terminals. Standard fitting mains terminal blocks have L N E,
where appropriate.
Mains terminal blocks on the emergency luminaires are marked Lc Ls N Earth.
Switching the voltage on the Ls connection enables the luminaire to be switched on and off without the
emergency function being activated. The Ls connection is insulated from Lc and has a signal function only
drawing a very small current.
The emergency units can be connected as switched or un-switched as standard, an non-maintained units on
request. The switching facility is to allow the luminaire to be switched off whilst still charging the battery. Where
switching is required, the un-switched line (Lc) is connected to the continuous mains supply. A link is fitted during
assembly between Lc and switched line (Ls); this is removed for the switch-able mode. If the link is removed and
Ls not supplied, the unit will only operate on emergency.
3.7.1 Installation of HF and Emergency
Following the mounting of the apparatus and the connection of the supply cable the unit
cannot
be insulation
tested. When the unit is ready for operation the mains and the battery connections must be made, the unit is
supplied with the battery disconnected. After commissioning the unit can be shut down for a long period without
loss of function. However with emergency versions the battery should be disconnected to ensure battery life is
maintained.
3.8 Servicing and Operation
3.8.1 Opening and Closing the Cover
The procedure for opening the cover is as follows:
Insert the tool into one of the slots in the clamping bar with the end of the tool located into the outer flange of the
body as a fulcrum point, a wide blade screwdriver is recommended. Gently lever the tool away from the diffuser,
