position and that no rectiers 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 rectiers
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 oat 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 o:………°C
