4. Hardware Overview
4.1. Applying Power to RPC-4850 Series Units
Note:ThisprocedurediffersforRPC-40L8A4seriesunits.Forinstructionson

Refer to power rating nameplate on the back panel, and then connect the RPC-4850
series unit to an appropriate power source as shown in Figure 4.1.
RPC-4850 series units features two separate DC inputs; connect power cables to
the unit's Circuit "A" and/or Circuit "B" terminal blocks, then connect the cables to an
appropriate power supply. 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 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.
CAUTIONS:
• Before attempting to install this unit, please review the warnings and
cautions listed at the front of the user's guide.
• This device should only be operated with the type of power source
indicated on the instrument nameplate. If you are not sure of the type of
power service available, please contact your local power company.
• Reliable earthing (grounding) of this unit must be maintained. Particular
attention should be given to supply connections when connecting to
power strips, rather than directly to the branch circuit.
