FR-F 740 EC

A large number of options allows an
individual adoption of the inverter to
the according task. The options can be
installed quickly and easily. Detailed in-
formation on installation and functions
is included in the manual of the options.

The options can be divided into two major
categories:

앬

Internal options

앬

External options

The internal options comprise input and
output extensions as well as communica-
tions options supporting the operation of
the inverter within a network or connected
to a personal computer or PLC.
