Using Intelligent Input Terminals

Terminals [1], [2], [3], [4], and [5] are identical, programmable inputs for general use.
The input circuits can use the inverter's internal (isolated) +24V field supply or an
external power supply. This section describes input circuits operation and how to
connect them properly to switches or transistor outputs on field devices.
The X200 inverter features selectable
the connection to the external switching device–it either
to GND) or
sink/source naming convention may be different in your particular country or industry.
In any case, just follow the wiring diagrams in this section for your application.
The inverter has a short bar (jumper) for
configuring the choice of sinking or sourcing
inputs. To access it, you must remove the
front cover of the inverter housing. In the
figure to the top right, the short bar is
shown as attached to the logic terminal
block (connector). For EU and US version
(suffix –xFE, and –xFU), it is originally
located as source type logic. If you need to
change to the sink type connection, remove
the short bar and connect it as shown in the
figure at the bottom right.
CAUTION: Be sure to turn OFF power to the inverter before changing the short circuit
bar position. Otherwise, damage to the inverter circuitry may occur.
