5.8 Commissioning record
This is a step-by-step commissioning record for easy commissioning of Power Supply
Systems. Do not continue if any faults occur during this commissioning. The checkpoints
are to be considered as a minimum for commissioning of the system.
Checked
(
)
Result
1
Check that the rack is level
2
Check that all breakers are turned to “off”
position and that no rectifiers are mounted in the
subrack(s).
3
Connect AC, and measure voltage on the mains
input connections in the cabinet, Is to be 230V
AC (Measure 230V from phase to N when 400V
mains input is used)
L1-N:……….V AC
L2-N:...............V AC
L3-N:...............V AC
4
Mount the rest of the rectifiers
5
After connection of battery, verify right polarity
by measuring the voltage drop across the battery
breakers (normally not more than 5V DC).
6
Check float charge, U1, and boost charge, U2.
It is to be adjusted according to the battery
manufacturers requirements.
U1:…….V DC
U2:.........V DC
7
Check temperature compensation. It is to be
adjusted according to the battery manufacture
requirements.
Check temperature read from the controller
compared to the ambient temperature.
Comp.:…….V/10°C
Read off:………°C
8
Check symmetry measurement and set number
of battery strings according to actual number of
supervised battery strings in the system.
Number: ….
Alarm limit:……
9
Check alarm transmission by running an alarm
test.
