Wiring
Installation
TR1 Series variable frequency
drive contains dangerous voltages
when connected to line power.
After disconnecting from line, wait
at least 14 minutes before
touching any electrical com-
ponents.
Only a competent electrician
should carry out electrical
installation. Improper installation
of motor or TR1 drive can cause
equipment failure, serious injury
or death. Follow this manual,
National Electrical Code and local
safety codes.
WARNING
!
CAUTION
!
CAUTION
!
Electronic components of TR1
variable frequency drives are
sensitive to electrostatic dis-
charge (ESD). ESD can reduce
performance or destroy sensitive
electronic components. Follow
proper ESD procedures during
installation or servicing to prevent
damage.
It is responsibility of user or
installer of TR1 Series variable
frequency drive to provide proper
grounding and motor overload
and branch protection according
to National Electrical Code and
local codes.
DANGER
!
The variable frequency drive generates a carrier
frequency with a pulse frequency between 3
kHz and 14 kHz. This results in radiated
frequency noise from the motor cables. It is
very important that the LonWorks cable be
isolated as much as possible from the drive

output cabling to the motor. Use the
recommended Trane Comm 5 twisted-
shielded pair when connecting to the TR1 VFD
(refer to BAS-SVN01A-EN). Do not run
LonWorks cabling and motor cables in parallel
or in close proximity to one another. Ensure
that the drive is properly grounded.
The following section describes the installation
procedures for the LonWorks option card (see
following illustration). For additional information
on installation and operation of the TR1 Series
VFD, refer to the TR1
