Chapter 3 PowerBrick™ Installation
In addition to the PowerBricks, a voltage sensing board is to be connected in the
power circuit.
Table 2 lists the voltage sensing board catalog numbers.
Table 2 - Voltage Sensing Board Catalog Number
Sizing the Enclosure
Use the data in Table 3 to assist in calculating the enclosure size.
Table 3 - PowerBrick Specifications
Catalog Number Voltage Sensing Board Input (3 phase, 50/60 Hz)
7703E-VSM 10,000…12,000V
7703E-VSN 12,001…14,400V
ATTENTION: The enclosure for the power stack assemblies must be adequately
sized to provide sufficient airflow to cool the units. Failure to provide adequate
cooling may result in reduced duty cycles or component failure.
