INSTALLATION AND COMMISSIONING
The installation and commissioning of Brooks FT420 CIE shall be carried out by qualified and trained
installers following the requirements of all the related current standards and regulations, such as
AS1670, AS/NZ 3000 and AS/ACIF S-009. Additional procedures detailed in this Chapter must also
be followed.
If any measurements are required during the installation and commissioning, only calibrated and
certified multimeters should be used. The CIE test results and maintenance history shall be recorded
in the forms provided in the APPENDICES from page 71 onwards. Duplicate the forms as necessary
and attach all results to this manual.
5.1 Installation
The Brooks FT420 system is factory pre-wired and fully tested before delivery to the site of installation.
After delivery to site, the system should be carefully checked for any possible mechanical damage
before commencing installation.
The FT420 cabinet can be mounted directly on a flat wall surface or into a wall recess using suitable
hardware.
5.1.1 AC Mains Supply and Battery Check
The FT420 system is connected permanently to the line side of the mains fuses at the main
distribution board.
The mains cable should be separated from other cables entering the cabinet. It should be wired
straight into the termination box situated in the top left hand corner of the cabinet. The mains earth
wire must be terminated at the main earth stud near the mains termination block.
Ensure the mains isolate switch in FT420 cabinet is OFF, do not connect the batteries.
Before applying power to the CIE, the voltage of each battery shall be measured using a multimeter. If
a 12V battery voltage is less than 10.7V, the battery shall be replaced since it might have been deeply
discharged or depleted.
Apply the mains power then measure and calibrate (if required)
18
the battery charging voltage as
follow:
1. Measure the voltage between the Battery terminals. The voltage should be between 27.3V
–
27.5V.
2. If the voltage is out of the range, adjust the trimpot on the AC/DC power supply, refer to
(Figure 38 below) until the voltage falls within 27.3 -27.5V (Turning anticlockwise to increase
voltage).
3. Connect the batteries
4. Record the final battery charger output voltage on the related spread sheet in Appendix A.
18
The power supply voltage is pre-adjusted in the factory, the procedures are required only if the voltage measurement differs
from the recommended values.
