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
Figure 6
. These busbars provide clearance holes or slots for installation of customer-provided two hole
lugs. Customer must order or supply lugs and lug mounting hardware.
