Throughout this manual, the following notes are used to alert you to safety
considerations:
Important: Identifies information that is critical for successful application and
understanding of the product.

ATTENTION: Identifies information about practices or
circumstances that can lead to personal injury or death, property
damage, or economic loss.

ATTENTION: The drive may contain high voltages that can cause
injury or death. Remove all power from the drive, and then verify
power has been removed before installing or removing an RS485
DF1 module. Failure to observe these precautions could result in
severe bodily injury or loss of life.
ATTENTION: Only qualified electrical personnel familiar with
drive and power products and the associated machinery should
plan or implement the installation, start up, configuration, and
subsequent maintenance of the product using an RS485 DF1
module. Read and understand this manual in its entirety before
proceeding. Failure to observe these precautions could result
bodily injury and/or damage to equipment.
ATTENTION: DPI host products must not be directly connected
together via RECBL-xxx cables. Unpredictable behavior due to
timing and other internal procedures can result if two or more
devices are connected in this manner. Failure to observe this
precaution could result in bodily injury and/or damage to
equipment.
ATTENTION: If the RS485 DF1 module is transmitting control
I/O to the drive, the drive may fault when you reset the module.
Determine how your drive will respond before resetting a module.
Failure to observe this precaution could result bodily injury
and/or damage to equipment.
ATTENTION: Comm Flt Action (parameter 10) lets you determine
the action of the module and connected drive if communications
are disrupted. By default, this parameter faults the drive. You can
set this parameter so that the drive continues to run. Precautions
should be taken to ensure that the setting of this parameter does
not create a hazard of injury or equipment damage. When
commissioning the drive, verify that your system responds
correctly to various situations (for example, a disconnected cable
or a faulted controller). Failure to observe this precaution could
result bodily injury and/or damage to equipment.
ATTENTION: When a system is configured for the first time, there
may be unintended or incorrect machine motion. Disconnect the
motor from the machine or process during initial system testing.
Failure to observe this precaution could result in bodily injury
and/or damage to equipment.
