Current Inputs
For each current input, you must install a resistor. The value
of the resistor must be correct for the expected input range. In-
stall the resistor in the listed resistor pack (RP) location. Note
the resistor pack locations have three through-holes. Install
the resistor as shown in the illustration below.
