 CAUTION
1) Be careful of polarity when wiring inputs. Reversed polarity can damage the UP.
2) Keep the remote (auxiliary analog) input signal line as far away as possible from
the power supply circuit and ground circuit.
3) For TC input (remote input with direct input), use shielded compensating lead
wires for wiring. For RTD input, use shielded wires that have low conductor
resistance and cause no significant differences in resistance between the three
wires.
4) If there is a risk of external lightning surges, use a lightning arrester etc.

RSPRemoteInput(E1-terminalarea)
In Single-loop control, used for remote input.
In Cascade primary-loop control, remote input is used for output tracking input.
In Cascade control, remote input is used for Loop-2 PV input.
In Loop control with PV switching or Loop control with PV auto-selector, remote input is
used for PV input 2.
AIN2AuxiliaryAnalogInput(E2-terminalarea)
In Loop control with PV auto-selector for 3 inputs or 4 inputs, auxiliary analog input (E-2
terminal area) is used for PV input 3.
AIN4AuxiliaryAnalogInput(E4-terminalarea)
In Loop control with PV auto-selector for 4 inputs, auxiliary analog input (E4-terminal
area) is used for PV input 4.
