Mandatory
Mandatory
Do not touch the sharp portions (such as leads of parts on the board, the corner of board,
or etc.) on this option.
It may lead to injuries.
Warning
This option is an electrostatic discharge sensitive device. Handle it, where the
environment is protected against electrostatic electricity.
Otherwise, permanent damage to device will result.
Transportation and installation
Danger

Otherwise, damage or malfunction will result.
Do not install or operate the inverter if it is damaged or any part of it is missing.
Operating a defective inverter may lead to electric shocks or fire.
For repairs, call your sales/repair agency.
Prohibited
Do not put any flammable material near the product.
It may catch fire due to the product sparking in the case of a malfunction.
Use this product under the environmental conditions prescribed in the instruction manual.
Usage it under any other conditions may result in malfunction.
An emergency stop device must be installed that fits with system specifications
(e.g. shut off input power then engage mechanical brake).
Operation cannot be stopped immediately by the inverter or this unit alone, thus risking an
accident or injuries.
Install this option into VF-FS1 and secure it by tightening the terminal board fixing
screws to the specified torque. Otherwise, it may cause the product falling, the damage,
or malfunctions.

Wiring
Warning
Electrical construction work must be done by a qualified expert.
Connection of input power by someone who does not have expert knowledge may result
in electric shocks or fire.
Turn off input power before wiring.
Wait at least 10 minutes and make sure that the charge lamp (on the inverter unit) is no
longer lit. Otherwise, it may lead to electric shocks.
Tighten the screws on the terminal blocks to the specified torque when connecting cables
to terminal blocks.
Mandatory
Otherwise, it may lead to fire.
Operations
Danger
Do not pull on the cable and connector.
It may cause damage or malfunctions.
Prohibited
Mandatory
Use this option under the environment specified in the instruction manual.
Usage under the environment other than them may cause damages or malfunctions or
an accident.
Use an additional safety device with your inverter or system to prevent a serious
accident due to the unit malfunctions.
Usage without an additional safety device may cause an accident.
Warning
Set up ³Communication error trip function (see below)´ to stop the inverter when the
option unit is deactivated by an unusual event such as an operating error, power outage,
failure, etc.
- Communication error trip time (Between the inverter and option board) (f803)
- Network timeout (f892)
®
(See the VF-FS1 BACnet Communication Function Manual for details)
Mandatory
Disposal
Deactivated option unit may cause an accident, if the ³Communication error trip
function´ is not properly set up.
Make sure that the operation signals are STOP before resetting inverter¶s fault. The
motor may suddenly start and that may result in injuries.
Warning
If you dispose off this unit, have it done by a specialist in industrial waste disposal*.
Improper disposal may result in explosion of capacitors or produce noxious gases,
resulting in injuries.
(*) Persons who specialize in the processing of waste and known as ³Industrial Waste
Product Collectors and Transporters´ or ³Industrial Waste Disposal Persons.´ If the
collection, transport and disposal of industrial waste is done by someone who is not
licensed for that job, it is a punishable violation of the law (Laws in regard to cleaning and
processing of waste materials).
Mandatory
Notes on operation
Notes
Avoidꢀinstalling in a place where ambient temperature or/and humidity change sharply.
Keep the transmission cable separate from the power cable of the inverter to prevent the
inverter from malfunctioning due to electromagnetic noise.
Ground of SCR terminal on this option at the grounding terminal separated from those of
inverters and motors. It may cause malfunction due to noise.

3. Installation and Setup
3.1. Installation method
Install the BACnet communication option to VF-FS1 as follows.
(1) Turn off the input power of VF-FS1 and wait for at least 10 minutes and then check that the
CHARGE lamp on VF-FS1 is no longer lit.
(2) Open the VF-FS1 front cover, remove the terminal board fixing screw and take off the VF-FS1
standard terminal board.
(Be careful not to lose the terminal board fixing screw when removed since it may be used again.)
(3) Perform wiring an inverter before installing BACnet communication option.
(4) Please attach the insulating sheet in VF-FS1.
(Fix to the terminal board fixing screw hole and PWB catch pin.)
(5) Install the BACnet communication option over the insulating sheet and secure it with the board
fixing screw (tightening torque of M3 tapping screw: 0.7 to 0.8Nm).
(6) Set up the SW of the board with the input terminal for sink or source.
(7) Stick the cabling label for BACnet communication option on the standard cabling label stuck on
the reverse side of the VF-FS1 front cover. And stick the BACnet communication option
nameplate near the standard nameplate. (Be careful not to cover slits on the VF-FS1 enclosure.
N.B.: To install or remove the terminal board, make it slide in or out in parallel with board.

Tightening torque for the terminal block is 0.5Nm.
* Fix a cable so that a communication connector may be not taken the weight of wire.
3.4. Network configuration
Make up the network as follows.
- Transmission/reception signals (A, B)
Make up the communication path by connecting all transmission/reception data cables.
- Signal common (GND)
GND is the signal common.
- Grounding the shield of cable (SCR)
Connect the all shield lines of network cable. The shield shall be grounded at one end only prevent
currents from being created.
- Termination resistor
A termination resistance of 120 ohms plus or minus 5% shall be connected at each of the two ends
of the segment medium. This option has a termination resistor, so if use, set up the termination
resistor SW. (Refer to 2.1 Outline)
At least one set, and no more than two sets, of network bias resistors shall exist for each segment.
This option has local bias resistors.

3.5. Wiring of a control terminal
Observe the following when wiring.
- Use 0.3 to 1.5mm2 solid/stranded wire (AWG 22 to 16) for control cables.
- Remove the sheath of a cable about 7mm (6mm for FLA, FLB, FLC and G/E) from the end of cable.
- Use a flat-headed screwdriver with its blade 0.6mm in thickness and 3.5mm in width.
- Screw tightening torque for the terminal block screws should be 0.5 to 0.6Nm.
N.B.: Keep the control signal cables 20cm or more separate from the power cables to prevent from
malfunctioning due to electromagnetic noise.
N.B.: Provide an inter-lock system stated in below, when using a programmable controller that has
the open collector output.
When the programmable controller is turned off with the inverter is on, the difference between
each control power potential will cause wrong signals to the inverter as shown in below figure.
Provide an inter-lock so that the programmable controller cannot be turned off when the
inverter power is alive.
