WARNING
Risk of serious personal injury or damage to equipment and property! Always
observe the following:
•
Shut off or disconnect all dc power sources before connecting or
disconnecting wiring
•
Use wire and connectors rated for the maximum load current and size of fuse,
and keep cable lengths as short as practical
•
Carefully observe wiring polarity when making input and output connections
•
Securely tighten all connections
Bond the panel chassis to the rack system ground, connecting a ground wire with
ring tongue to the back panel ground stud. (8-32 thread)
Connect Bus A loads to each output channel using suitably rated wire (10 AWG
maximum) sized for the fuse installed on the channel, stripping 10-11mm of
insulation and firmly clamping in the Bus A channel 1 to 10 output connectors.
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 (20 to 60 volts DC) of either polarity, but must share
a common RTN voltage, normally at earth potential.
Connect the main Bus A RTN line to an external DC power supply return using
suitably sized wire and dual hole lug connector rated for up to 100 amperes
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 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.
If the Bus B outputs are to be used, please configure Bus B the same as Bus A.
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
