NSTRUCTIONS
In the event of loss of mains, a battery fault or a PSU fault, the corresponding Fault signal contacts will open. If the output of
the PSU fails, the cause of the failure should be investigated e.g. short circuit load, connection of a deeply discharged
battery. The fault should be rectified before restoring power to the PSU. If any of the fuses require replacing, ensure the
correct fuse rating and type is used.

AINTENANCE
This unit is intended for use by Service Personnel only. There are NO USER SERVICEABLE parts inside.
There is no regular maintenance required of the PSU other than periodic testing, calibration check and replacement of the
standby batteries.
Reference should be made to the battery manufacturer's documentation to determine
typical/expected battery life with a view to periodic replacement of the battery.

ALIBRATION
C
HECK
This power supply does not require calibration. If it is necessary to validate the calibration to comply with system inspection
requirements then use the following procedure.
1)
Set a calibrated DVM on maximum resolution range to read 6.00 Vdc.
2)
Connect meter to calibration pins marked J4.
3)
Verify that the meter reading is within the range 5.00 – 5.50 Vdc.
If the unit fails its calibration check, it will continue to function but with reduced accuracy of detection of Low Battery
voltage and Low output voltage. Please contact the manufacturer for recalibration options.

PERATION
The unit may be operated with only one battery. To avoid generating a fault condition cve (red) battery lead to
Bat1+ and Bat2+, and connect the -ve (black) Battery lead to either Bat1- or Bat2-.
CAUTION
Dispose of used batteries according to the battery manufacturer’s
instructions and all local and national regulations.
