Introduction
The 890 Common Bus Adaptors are designed to interconnect 890CD Common Bus Drives using the
SSD_Rail busbar system.
Each Adaptor provides a busbar and a terminal connection for DC+ and DC-. This allows flexible
wiring between rows of busbar-connected units.
Two versions are available:
1. Enclosure/Row Changer (890CA////00).
2. Power Loss Ride-Through Adaptor (890CA////RT) - contains additional bus capacitance to
help a system ride-through a mains power loss, without having an under-voltage trip. Can also
be used as an enclosure/row changer.

•You realise that this guide contains only basic information and that you may need to refer to the
Engineering Reference Guide supplied with the 890 Drive to complete your installation.
SSD_Rail Busbar System
Since the height and depth of every
module is the same, it is very convenient
to assemble drives of varying frame sizes
into one common bus system. Typically
they are installed side-by-side.
SSD_Rail is an innovative busbar system
that connects the DC+ and DC- terminals
of all drives on a common bus without the
use of wire.
