End of Battery Discharge (EOD): The point at which the batteries are fully discharged (default

1.75V/C * 18 cells for 36V inverter) and the power supply shuts off, preventing permanent damage
to the batteries.

Frequency Range Limit (may be used when powering with AC Generator): AC input voltage
frequency range limit. This limit establishes the acceptable input frequency range outside of which
standby operation is initiated.

Output 1 Overcurrent Trip level

Primary leg: Value of RMS current that causes an overcurrent

trip on the Output 1A + Output 1B protection relay after a specified delay. This limit is linked to
counter data item Overcurrent Tolerance Period. This parameter is only visible when the Protective

Interface Module (PIM) is attached.
Output 2 Overcurrent Trip level

Secondary leg: Value of RMS current that causes an

overcurrent trip on the Output 2 protection relay after a specified delay. This limit is linked to
counter data item Overcurrent Tolerances Period. This parameter is only visible when the optional
PIM is attached.

Battery Type

: (HP models only) The AlphaCell battery type can be specified in the smart display

(if not AlphaCell, leave as default battery type, Other). If AlphaCell is selected, Accept, Float,
Temp, Comp and Battery Capacity is automatically selected. If Other, these parameters will need

to be manually set to the manufacturer’s recommended rating.

4.6 Smart Display Glossary

Battery Capacity: The capacity of the battery strings attached to a particular Intelligent

CableUPS. When batteries are not attached, the setting must be programmed to “0.” This disables
standby operations, including test mode and disables the No Batteries Alarm. If batteries are
attached, then this setting should be programmed to the total rating of all the battery strings.
This setting can be programmed to higher values to accommodate multiple battery strings (i.e., 1
battery string = 100 AH, 2 battery strings = 200 AH, 3 battery strings = 300 AH. 4 battery

strings = 400AH).

If the power supply is used in a non-standby application, this variable must be programmed to “0” to
disable the battery maintenance cycle portion of a self test.

NOTE:

Charger Accept Voltage: Battery Accept charge voltage control in volts per cell. This voltage,

2.40Vdc (adjustable) per cell, is temperature compensated to ensure longer battery life. It properly

completes the charge cycle and is factory set for AlphaCell batteries. If another manufacturer’s
batteries are used, consult the battery manufacturer for Accept voltage levels.

Charger Float Voltage: Battery Float charge voltage control in volts per cell. The average is

approximately 2.27Vdc (adjustable) per cell. It is factory set for AlphaCell batteries. If another

manufacturer’s batteries are used, consult the battery manufacturer for Float voltage levels.
Charger Temperature Compensation: Battery charger temperature compensation control.

Programming this parameter to “0.0” disables temperature compensation. It is factory set for

AlphaCell batteries (5mV/cell). If another manufacturer’s batteries are used, consult the battery
manufacturer for Charger Temperature compensation ranges.

Device Address: The power supply must have a unique address to communicate with a system

controller. The system controller uses the address as an identifier to query the power supply for

information. Each power supply on the same communications bus must be identified with a value
between 1 and 7.

If AlphaCell is selected, Accept, Float, Temperature Compensation and Battery Capacity are not
displayed.

NOTE:

The device address does not reset to 1 when factory defaults are reset.
