1 DESCRI TION
The emergency power supply ensures the unit's functionality in the event of failure of the
main power supply. It will be carried out by a system of charger and batteries certified
according to EN 54.
2 EMERGENCY OWER SU LY
For maintenance and revision the different components of the emergency power supply in
the NEO series devices are detailed. Their sections are shown in diagram 2:
Diagram : NEO device rear side detailed
Power supply: Emergency power input terminal specific to each NEO series device.
Supervision: emergency power supply pins (power supply status outputs) including
three contact closure inputs.
Each monitoring input has three terminals: Normally Closed (NC) Common and Normally
Open (NO). To activate any fault signals a contact closure must occur on the NO input while
an opening of the NC input.
The NEO series devices read the fault signal when the contact closure on the NC input is
opened. Note that this logic is opposite to that used by the chargers supplied by LDA so the
wiring should be connected as shown in diagram 3.
3 WIRING INSTRUCTIONS
1. Make sure the battery charger is actually disconnected before start the process.
2. Connect the negative pole from first battery to positive pole at second battery.
3. Connect the negative pole from second battery to the battery charger negative input.
4. Connect the positive pole from first battery to the battery charger positive input.
5. Connect battery charger output to NEO series device.
6. Connect the 9 pins of the supervision from the charger to NEO device.
