3. Maintenance
1. It is essential that all SPARTAN Bulkhead units are maintained in accordance with
the requirements of the EN60079-17 standard: (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.
• For Emergency variants, battery must be isolated/ connected when a hazardous
environment is NOT present prior to 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.
5. The unit has one independent power supply, in the event that the power supply
needs to be replaced the cables to the LED and mains terminal block will need to
be disconnected, the four M6 bolts released, then the power supply can then be
removed. Fitting a new power supply is a reversal of the above procedure.
6. Disposal of packaging, SPARTAN unit and old LED assemblies should be carried out
in accordance with national regulations.
