Connecting a DC Reactor
A DC reactor can be installed to the drive. When installing a DC reactor, remove the jumper between terminals +1 and +2
(terminals are jumpered for shipment). The jumper must be installed if not using a DC reactor. Refer to Figure 8.10 for an
example of DC reactor wiring.

Installing Input Fuses
Always install input fuses at the drive input side of the drive to prevent damage from short circuits.
Select the appropriate fuse from the table below.

Attachment for External Heatsink Mounting
An external attachment can be used to project the heatsink outside of an enclosure to ensure that there is sufficient air circulation
around the heatsink.
Contact a Yaskawa sales representative or Yaskawa directly for more information on this attachment.

Installing a Motor Thermal Overload (oL) Relay on the Drive Output
Motor thermal overload relays protect the motor by disconnecting power lines to the motor due to a motor overload condition.
Install a motor thermal overload relay between the drive and motor:
• When operating multiple motors on a single AC drive.
• When using a power line bypass to operate the motor directly from the power line.
It is not necessary to install a motor thermal overload relay when operating a single motor from a single AC drive. The AC
drive has UL recognized electronic motor overload protection built into the drive software.
Note: 1. Disable the motor protection function (L1-01 = 0) when using an external motor thermal overload relay.
2. The relay should shut off main power on the input side of the main circuit when triggered.
