■Section Safety
General Precautions
•The diagrams in this section may include options and drives without covers or safety shields to illustrate
details. Be sure to reinstall covers or shields before operating any devices. The option should be used
according to the instructions described in this manual.
•The diagrams in this manual are provided as examples only and may not pertain to all products covered by this
manual.
•The products and specifications described in this manual or the content and presentation of the manual may be
changed without notice to improve the product and/or the manual.
•Contact Yaskawa or a Yaskawa representative and provide the manual number shown on the front cover to
order new copies of the manual.
DANGER Do not ignore the safety messages in this manual. If you ignore the safety
messages in this manual, it will cause serious injury or death. The manufacturer is not responsible for
injuries or damage to equipment.
WARNING Electrical Shock Hazard. Do not modify the drive or option circuitry. Failure to obey
can cause serious injury or death, or cause damage to the drive or option and will void warranty. Yaskawa
is not responsible for modifications of the product made by the user.
NOTICE Damage to Equipment. Do not use steam or other disinfectants to fumigate wood
for packaging the drive. Use alternative methods, for example heat treatment, before you package the
components. Gas from wood packaging fumigated with halogen disinfectants, for example fluorine,
chlorine, bromine, iodine or DOP gas (phthalic acid ester), can cause damage to the drive.
2 Overview
◆About This Option
The BACnet MS/TP Communication Option (Model SI-B3) connects a Yaskawa drive to
a Building Automation and Control network (BACnet) network and facilitates the
exchange of data.
When you install the option to the drive, you can use the BACnet protocol to do these
operations:
•Operate the drive
•Monitor the drive operation status
•Change drive parameter settings
Up to 127 drives can communicate on a single BACnet MS/TP network. Applications
requiring more drives or BACnet devices require a BACnet router to allow another MS/
TP network to be available with up to another 127 drives. Actual maximum number of
units depends on total network transceiver load. Refer to EIA-485 standards for more
information about network hardware specifications.

5 Installation Procedure
◆Section Safety
DANGER Electrical Shock Hazard. Do not examine, connect, or disconnect wiring on an
energized drive. Before servicing, disconnect all power to the equipment and wait for the time specified on
the warning label at a minimum. The internal capacitor stays charged after the drive is de-energized. The
charge indicator LED extinguishes when the DC bus voltage decreases below 50 Vdc. When all indicators
are OFF, measure for dangerous voltages to make sure that the drive is safe. If you do work on the drive
when it is energized, it will cause serious injury or death from electrical shock.
WARNING Electrical Shock Hazard. Do not operate the drive when covers are missing.
Replace covers and shields before you operate the drive. Use the drive only as specified by the
instructions. Some figures in this section include drives without covers or safety shields to more clearly
show the inside of the drive. If covers or safety shields are missing from the drive, it can cause serious
injury or death.
WARNING Electrical Shock Hazard. Only let approved personnel install, wire, maintain,
examine, replace parts, and repair the drive. If personnel are not approved, it can cause serious injury or
death.

5 Installation Procedure
YASKAWA TOEP YAICOM 22A BACnet MS/TP Installation & Technical Manual 13
WARNING Electrical Shock Hazard. Do not remove covers or touch circuit boards while the
drive is energized. If you touch the internal components of an energized drive, it can cause serious injury
or death.
WARNING Electrical Shock Hazard. Do not use damaged wires, put too much force on the
wiring, or cause damage to the wire insulation. Damaged wires can cause serious injury or death.
WARNING Fire Hazard. Tighten all terminal screws to the correct tightening torque.
Connections that are too loose or too tight can cause incorrect operation and damage to the drive.
Incorrect connections can also cause death or serious injury from fire.
NOTICE Damage to Equipment. When you touch the option, make sure that you observe
correct electrostatic discharge (ESD) procedures. If you do not follow procedures, it can cause ESD
damage to the drive circuitry.
NOTICE Damage to Equipment. Do not de-energize the drive while the drive is outputting
voltage. Incorrect equipment sequencing can cause damage to the drive.
NOTICE Do not operate a drive or connected equipment that has damaged or missing parts.
You can cause damage to the drive and connected equipment.
NOTICE Use Yaskawa connection cables or recommended cables only. Incorrect cables
can cause the drive or option to function incorrectly.
NOTICE Damage to Equipment. Correctly connect the connectors. Incorrect connections
can cause malfunction or damage to the equipment.
NOTICE Damage to Equipment. Make sure that all connections are correct after you install
the drive and connecting peripheral devices. Incorrect connections can cause damage to the option.
◆Procedures to Install and Wire Options on a Drive
