3. Open terminal block enclosure
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
7. All SPARTAN floodlights/highbay have terminal blocks suitable for looping 4mm2
cable, only one cable should be connected to each terminal block connection – when
incoming cables are installed a creepage and clearance of 5mm and 4mm respectively.
8. To use DALI/Dimming interface, connect the DALI terminals on the terminal block
9. Ensure no cables are trapped and gasket is seated correctly and replace terminal
block cover. Tighten to 4Nm
10. If carrying out Insulation Resistance tests the normal method of insulation testing
is to connect Live and Neutral together and test between this point and Earth to
prevent the risk of damage to the electronic control gear.
Wire the Mains cable into the terminal block. Provision has been made for this and identified
as the E (Earth), L1 (Switched Live), L2 (permanent live) 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 L2 terminals on a standard unit are not electrically connected but allows
them to be used on the same circuits as
emergency bulkheads.
