C.6. INSTALLATION
C.6.1 Battery Backup Unit Installation
The procedure for installing and commissioning an AFL Cell Enhancer Battery Backup Unit is
generally as follows:
1 Fix the Battery Backup Unit in the chosen position.
2 Connect a suitable mains power supply to the Battery Backup Unit.
3 Connect the DC cable from the Battery Backup Unit to the Cell Enhancer.
4 Switch the Battery Backup Unit on by switching on the two circuit breakers and the
battery output switch on the internal indicator panel.
5 Test the Cell Enhancer to ensure correct operation from the Battery Backup Unit.
C.6.2 Power Supply Input Voltage Selection
The SMPSU module used within the AFL Cell Enhancer Battery Backup Unit is capable of
operation at any voltage between 90 Vac and 264 Vac. The battery charger power supply (Traco)
must be switched to either 115 or 230V nominal AC supplies. The supply changeover switch is
located on the top surface of the battery charger supply near to the front of the battery backup
case. This slide switch is recessed within the supply and can be operated by a small screwdriver.
C.7. MAINTENANCE
C.7.1 General Comments
The AFL Cell Enhancer Battery Backup Unit requires no routine maintenance. If a failure is
suspected it is possible with the aid of the block schematics (see section 3) to locate any
defective unit.
It should be borne in mind that a failure indicated by the alarm system could actually be a failure
in the alarm system! It is always worth checking that there really is a genuine problem by AC and
DC voltage measurements before starting to dismantle parts of the system. Lead-acid batteries
should be inspected every year for general condition the same way an auto battery would be
regarded.
