3. Quick Start
This Quick Start Guide describes a simpliﬁed installation procedure for the
RPC-4850-8N hardware, which will allow you to communicate with the unit in
order to demonstrate basic features and check for proper operation.
Note that this Quick Start procedure does not provide a detailed description
of unit conﬁguration, or discuss advanced operating features in detail. For
more information, please refer to the installation, conﬁguration and operation
sections in this User's Guide.
3.1. Hardware Installation
3.1.1. Apply Power to the RPC-4850-8N
Refer to power rating nameplate on the back panel, and then connect the RPC
unit to an appropriate -48 VDC, 50 Amp (maximum) power source as shown in
CAUTION: Prior to connecting power to the unit, make certain to
review the Safety Precautions listed at the beginning of this User's
The RPC features two separate DC inputs; connect power cables to the unit's
Circuit "A" and/or Circuit "B" terminal blocks, install the protective cover over
the Power Input terminal block, and then connect the cables to an appropriate
Note that it is not necessary to connect power to both input circuits; either
circuit will supply power for operation and control functions. However, when
power is connected to both input circuits, this allows the second circuit to
function as a back-up in the event of a power outage.
Note that each individual output circuit will support up to 15 Amps maximum,
and that the total for all eight circuits cannot exceed 50 Amps.
Once power is applied to the unit, the ON LED should light, and the RDY
LED should begin to ﬂash. This indicates that the RPC-4850-8N is ready to
