11)
With mains
disconnected,
connect the two 12 V standby batteries in series using the single cable provided.
Connect the
negative
of one battery to the
positive
of the other.
DO NOT CONNECT
the other two battery
terminals to each other.
12)
Connect the free Positive and Negative terminals of the batteries to the PCB terminals Batt+ and Batt -
using the cables provided. See Figure 2 and 3.
13)
Re-apply mains and, after the LED indicators initial start-up flash, verify that the yellow Fault LED does not
flash (battery connection detected). Verify that the remote GEN PSU Fault monitor shows a
closed
contact.
14)
Disconnect the mains power. Verify that the green Mains LED extinguishes and the yellows Fault LED starts
to pulse (indicating that the PSU is running from its standby batteries).
15)
If connected, verify that the EPS Fault monitor shows an
open
contact and the PSU Fault monitor shows a
closed
contact.
16)
Perform a full functional test of system including full alarm condition. Verify that the standby batteries can
support the system load. Note: ensure batteries have sufficient charge.
Final
17)
Reconnect the mains. Verify that the green Mains LED illuminates and the yellow Fault LED extinguishes.
18)
If connected, verify that the EPS Fault monitor shows a
closed
contact and the GEN PSU Fault monitor
shows a
closed
contact.
19)
Close cover and secure using fastening screws provided.
NOTE: Batteries must be connected before mains power is applied to enable the batteries to be utilised. When
replacing batteries, re-connect new batteries and then cycle the mains power.
In the event of loss of mains, a battery fault or a GEN 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.
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, and replacement of the
standby battery.
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.
