Installation Instructions

Secure Racking

If Secure Racked units are installed in a closed or multi-unit rack assembly, they may require further

evaluation by Certication Agencies. The following items must be considered.

1. The ambient within the rack may be greater than room ambient. Installation should be such
that the amount of air ow required for safe operation is not compromised. The maximum
temperature for the equipment in this environment is 45°C. Consideration should be given to the
maximum rated ambient.

2. Installation should be such that a hazardous stability condition is not achieved due to uneven
loading.

Input Supply

Check nameplate ratings to assure there is no overloading of supply circuits that could have an eect
on overcurrent protection and supply wiring.

Grounding

Reliable earthing of this equipment must be maintained. Particular attention should be given to
supply connections when connecting to power strips, rather than direct connections to the branch
circuit.

No Serviceable Parts Inside; Authorized Service Personnel Only

Do not attempt to repair or service this device yourself. Internal components must be serviced by
authorized personnel only.

Disconnect Power

If any of the following events are noted, immediately disconnect the unit from the circuit and contact
qualied service personnel:

1. If the power cord becomes frayed or damaged.

2. If liquid has been spilled into the device or if the device has been exposed to rain or water.

Two Power Supplies

Note that this unit includes two separate power circuits. Before attempting to service or remove this
unit, please make certain that both power sources are disconnected.

1. Introduction

This Quick Start Guide describes a simplied installation procedure for the
RPC-4850 Series 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 Guide does not provide a detailed description
of unit conguration or discuss advanced operating features in
detail. For more information, please refer to the User’s Guide,
which can be found on our web site at the address below, or by
scanning the QR Code to the right.

2. Hardware Installation

Apply Power to the RPC

Refer to power rating nameplate on the back panel, and then connect the RPC unit to an
appropriate power source as shown in Figure 1 or Figure 2.

The RPC 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.

The ON LED should light, and the RDY LED should begin to ash. This indicates that
the RPC is ready to receive commands.

Connect your PC to the RPC

The RPC can either be controlled by a local PC, that communicates with the unit via
cable, controlled via external modem, or controlled via TCP/IP network. In order to
switch circuits On/O or select parameters, commands are issued to the RPC via either
the Network Port or Console Port. Note that it is not necessary to connect to both the
Network and Console Ports, and that the Console Port can be connected to either a local
PC or External Modem.

• NetworkPort: Connect your 10Base-T or 100Base-T network interface to the RPC
Network port.

• ConsolePort: Use the null modem cable supplied with the unit to connect your PC
COM port to the RPC Console (RS232) Port.

• ExternalModem: Use a standard AT or modem cable to connect your external
modem to the RPC's Console (RS232) Port.
