Function and application
External
potentiometer for
frequency
commands
An external potentiometer may be used to set the drive frequency. Connect the
potentiometer to control signal terminals [11] to [13] of the inverter.
Multi-function
keypad
Allows you to monitor the status of the inverter including voltage, current, and
input power, as well as to set various parameters in a conversational mode.
Equipped with a liquid crystal display (LCD).
Also allows you to copy function code data from one FRENIC-Multi inverter to
another.
Extension cable
for remote
keypad operation
The extension cable connects the RS-485 communications port (standard)
with a keypad or an RS-485—USB converter.
Three lengths are available: 5 m, 3 m and 1 m
RS-485
Communications
card
This makes communication to a PLC or personal computer system easy.
(Option)
This has a pair of RJ-45 connectors that acts as a transfer port for a multidrop
network configuration without using a branch adapter.
RS-485—USB
converter
A converter that allows connection of an RS-485 communications port to a
USB port on a PC.

Inverter support
loader software
Inverter support loader software, Windows GUI (Graphics User Interface)
based, that makes setting of function codes easy.
Surge absorbers
A surge absorber suppresses surge currents and noise from the magnetic
contactors, mini-relays and timers, and protects the inverter from
malfunctioning.
Surge killers
A surge killer eliminates surge currents induced by lightening and noise from
the power supply lines. Use of a surge killer is effective in preventing the
electronic equipment, including inverters, from damage or malfunctioning
caused by such surges and/or noise.
Arresters
An arrester suppresses surge currents and noise invaded from the power
supply lines. Use of an arrester is effective in preventing electronic equipment,
including inverters, from damage or malfunctioning caused by such surges
and/or noise.

Frequency meter
Displays the frequency in accordance with signal output from the inverter.
Panel-mount
adapter
FRENIC-Multi series of inverters can be installed to your system panel or
equipment using mounting adapters which utilize the mounting holes used for
conventional inverters of FVR-E11S series.
(Three-phase 200 V: 0.1 to 0.75 and 3.7 kW, Three-phase 400 V: 3.7 kW,
Single-phase 200 V: 0.1 to 0.4 and 2.2 kW)
Other op
tions
Mounting adapter
for external
cooling
This adapter allows you to mount your FRENIC-Multi series of inverters on the
panel in such a way that the heat sink assembly may be exposed to the
outside. Using this adapter greatly reduces heat radiated or spread inside your
panel.
Applicable only to inverters with a capacity of 5.5 to 15 kW.
