APBU-44CE PPCS Branching and Datalogger Unit

The APBU-44C(E) PPCS Branching and Datalogger Unit is used to implement the
parallel connection of multiple ACS800 series inverter or supply modules. The
APBU-44C(E) also contains a datalogger for collecting and storing real-time data
from the module power stages to help fault tracing and analysis.
The APBU-44C(E) is a DIN rail-mountable unit and requires an external 24 V DC
power source.
The APBU-44C(E) is connected in the PPCS fibre optic link between the RDCU
drive control unit and the modules. The APBU-44C has connections for four inverter
or supply modules, while the APBU-44CE has connections for twelve.

With this setting ON, a fresh battery will retain the memory of an unpowered
APBU-44C(E) for at least 6 months.
The battery must be replaced if the ìBATî LED is not illuminated when the
APBU-44C(E) is powered and the battery is switched on (S3 actuator 6 is set to ON).

The manual describes the APBU-44C(E) unit and its usage. It also gives instructions
for installing the unit in a user-defined cabinet.
The manual is intended for cabinet designers and installation personnel of
ACS800 Multidrive modules, and commissioning and maintenance personnel of
ACS800 Multidrive modules and ACS800 Multidrive.
The reader is expected to know the standard electrical wiring practices, electronic
components, and electrical schematic symbols.
