Important Safety Instructions
DANGER!
Adhere to the “Important Safety Instructions” presented at the front of this document.
WARNING!
Observe proper polarity when making output connections.
General
NOTE!
The system is intended to be negative pole grounded (+12 VDC). Field provide a properly sized DC power return wire
to earth reference from the GND/RETURN busbar to Earth.
NOTE!
The installation may consist of one (1) main module mounting assembly and up to two (2) expansion module
mounting assemblies, or all main module mounting assemblies. In installations with one main module mounting assembly and
up to two expansion module mounting assemblies, all module mounting assemblies are on one DC bus and are controlled by
a single SCC controller. A common CAN bus is shared across all module mounting assemblies and all rectifiers load share
and all rectifiers are load managed via the SCC. In installations with all main module mounting assemblies, each module
mounting assembly is on a separate DC bus and each module mounting assembly is controlled by (contains) a separate SCC
controller. A separate CAN bus exists per module mounting assembly, rectifiers load share per module mounting assembly,
and rectifiers are load managed via an SCC per module mounting assembly.
DC output leads are connected to the output busbars located on the back of the module mounting assembly(s) as shown in
. These busbars provide clearance holes for installation of customer-provided two hole lugs. Customer must order or supply lugs
and lug mounting hardware.
