RPC-40L8A4 Series; Quick Start Guide
3. Hardware Installation
Apply Power to the RPC-408LA4
Refer to power rating nameplate on the back panel, and then remove the protective cover
from the terminal block and connect the RPC unit to an appropriate power source as
shown in Figure 2 below.
Note:
RPC-40L8A4 series units feature two completely independent buses,
and for each circuit, voltage is connected to the +/- terminal (for negative 48 or
positive 48 volt units, power is connected to the +/- terminals and for positive 24
and 12 volt units, positive power is also connected to the +/- terminals.)
Warning:
An exposed wire lead from a DC input power source can conduct
harmful levels of electricity. Make certain that no exposed portion of the DC
input wire extends from the terminal block.
Input voltages for RPC-40L8A4 units are described in the table below:
Model Number
Voltage
Voltage Range
RPC-40L8A4-48
+48 or - 48 VDC
18 to 72 VDC
RPC-40L8A4-24
+24 VDC
18 to 72 VDC
RPC-40L8A4-12

9 to 36 VDC
When you have finished connecting power lines to the RPC-40L8A4 unit, make certain to
replace the protective input terminal block cover.
