Bond the panel chassis to the rack system ground, connecting a ground wire with
ring tongue to the front panel ground stud. (1/4-20 thread)
Connect Bus A loads to output channels A1 to A4 using suitably rated wire sized
for the breaker installed on the channel, with crimped on spade lug terminals
compatible with the output terminal block screws. Note which load is connected
to each channel, for future reference.
Repeat for the Bus B loads if required. The unit may be operated with either Bus
A or Bus B powered, or both.
NOTE!
All channel RTN lines, and the main high power Bus A and Bus B RTN terminals
are common, and tied to a single internal Return bus. Bus A and Bus B inputs can
be wired to a different dc voltage (10 to 60Vdc) of either polarity, but must share
a common RTN voltage, normally at earth potential.
Connect the main Bus A RTN line to the external battery or power supply return
using suitably sized wire and dual hole lug connector rated for up to 100A
continuous current. Connect the lug to the dual ¼-20 thread Bus A Rtn studs, and
then securely fasten with the supplied hardware.
Connect the Bus A Input through a suitably rated disconnect switch (set in the
open position) with a fuse or circuit breaker rated for 100A max continuous
operation to the external battery or power supply output, using suitably sized
wire and a dual-hole Lug connector rated for 100A continuous current. Connect
the Input lug to the dual ¼-20 thread Bus A Input studs, then securely fasten with
the supplied hardware. Snap the clear cover on to the Bus A input connector to
help prevent accidental contact with the input stud connections.
Repeat input wiring for the Bus B input, its power source and over current
protection device, if the Bus B outputs are to be used. Bus A and Bus B Input and
output Return lines are internally connected together, so will share a common
ground. The Bus A and Bus B Input terminals are isolated, and support operation
from separate + or –10 to 60V power sources, as long as they share a common
Return potential.
Connect the two form-C relay bus alarm outputs to an external monitoring
system if needed, by stripping and terminating 16-28AWG alarm wiring in the
Alarm 7-pin connector plug (lower), and installing in the front panel. Each Bus
Alarm output will trigger for any breaker open, or other alarm related to any
channel on that bus (Factory Default). Most alarm conditions can be masked off
so that they will not trigger the Alarm output if required, using the web based
graphical interface.
