Revision B
Wire the Mains cable into the terminal block. Provision has been made for this and
identified as the E (Earth), L (Live), Ls (Live switched) and N (Neutral) terminals. There
are two pairs of contacts for each of these to facilitate a mains cable that can be looped
in and out of the unit. The Ls terminals on a standard unit are not electrically connected
but allows them to be used on the same circuits as
*emergency floodlights.
4.
Installer should earth the unit separately
– an internal and external earth point are
provided as standard
5.
Connect wires to mains supply.
6.
If the unit is opened for any reason, disconnect mains
–
*On emergency luminaires
there may be more than one mains supply
7.
All SPARTAN floodlights have terminal blocks suitable for looping 4mm
2
cable, only one
cable should be connected to each terminal block connection
8.
*The battery fuse located within the Bulkhead housing on emergency variants is
disconnected after final manufacturing testing. When installing the floodlight the battery
fuse will need to be reconnected and the unit charged for 24 hours and then discharged
(repeated 3 times) to bring the battery up to peak capacity.
9.
*If a 4 core cable is used on emergency luminaires
– L, Ls, N and E the link cable at the
front of the terminal block between L and Ls should be removed
10.
*During emergency operation the light output and duration will be determined by the
variant purchased
3. MAINTENANCE
1. It is essential that all SPARTAN Bulkhead units are maintained in accordance with the
requirements of the EN60079-17standard: (Electrical apparatus for explosive gas
atmospheres
– other than mines).
2.
IMPORTANT.
No modifications are permitted to the unit, all spare parts must be
purchased from the manufacturer, unauthorized modifications or spare parts will
invalidate certification and make the equipment dangerous.
3. Isolate the SPARTAN Bulkhead from the mains supply and allow to cool before carrying
out any maintenance work.
4. In the unlikely event of a number of LED
’s failing, the light engine assembly must be
replaced. This is achieved by loosening front cover bolts, disconnecting the white LED
cables to power supply, remove four M6 bolts from rear of light engine and pull the light
engine assembly clear. Re fitting a light engine is a reversal of the above procedure.
