operating voltage for nominal 48 volt plants or approximately
0.5 volt above operating voltage for nominal 24 volt plants. The
actual operating voltages in float and equalize modes are
determined by the battery manufacturer's recommendations and
by any restrictions imposed by the load equipment.
DIP switches must be set for the proper plant operating voltage
(24 or 48 volts). All DIP switches must be set for the same
operating voltage. The switch settings may be done as part of the
BD and HV level setting procedure in “Battery on Discharge
Threshold” and “High Voltage Shutdown Thresholds,”
respectively. See the DIP switch setting instructions in
“Controller Setup.” For batteryless plants, disable equalize and
use a 3-volt margin for the HV setting on 48 volt plants and a 1.5
volt margin for the HV setting on 24 volt plants.
If a battery plant has the boost charge feature, set both the HV
and EQ/HV DIP switches to the same voltage.
Rectifier Port
Selection
The ECS-6U controller is factory configured for use with Lucent
Technologies Lineage

2000 J855-series ferroresonant
rectifiers. Rectifier connections should be made to the respective
ports (Rectifier 1, etc.) on the lower tray backplane. These ports
correspond to the S3 positions on the RIB. (See Figure 4-8.)
To connect Lucent Technologies J855-series ferroresonant
rectifiers to the controller, set the S3 respective positions on the
RIB to On (closed).
To connect Lucent Technologies switch mode (SR) rectifiers or
non-Lucent rectifiers, or if no rectifier is connected, open the S3
respective positions on the RIB.
The same table of settings shown in Figure 4-9 also appears as a
label on the inside of the door of the controller. Standard
interface cables are listed in Table 4-D.
