Input Power Connection; Motor Wiring Connection; Grounding; Electronic Thermal Protection - Trane TR1 6002 Installation And Operation Manual

Run input power, motor wiring and control
wiring in three separate metallic conduits or
raceways for high frequency noise isolation.
Failure to isolate power, motor and control
wiring could result in less than optimum drive
and associated equipment performance.

Input Power Connection

For drives with no auxiliary enclosure, connect input power to drive
terminals L1, L2, and L3, (terminal numbers 91, 92, and 93). If an auxiliary
enclosure is provided, input power connections are made in the auxiliary
enclosure. Refer to the connection diagrams shipped with the drive.
Size wiring to the input current of the drive as shown in the tables
below. Maximum AWG wire size is also provided. Local codes must be
complied with for cable sizes.

Motor Wiring Connection

For drives with no auxiliary enclosure, connect the motor to drive
terminals U, V, and W (terminal numbers 96, 97, and 98). Terminal 99
is earth ground. If an auxiliary enclosure is provided, refer to the
connection diagrams shipped with the drive. Ground the shield on the
motor wire, if used, at both the drive and the motor.
NOTE
WARNING
!
Grounding Hazard!
For operator safety, it is important to ground
drive properly. Follow the grounding guidelines
provided. Failure to follow grounding guidlines
could result in death or serious injury.

Grounding

Ground the drive properly. Use a ground wire at least 7 AWG (10mm
Connect the ground wire directly to a reliable earth ground. Do not use
the conduit connecting to the drive as a replacement for a ground wire. Do
not ground one drive to another in a “daisy chain” fashion.

Electronic Thermal Protection

The electronic thermal relay is UL approved for single motor thermal
protection as long as the following is complied with:
1. Parameter 117, Thermal Protection, is set to ETR TRIP.
2. Parameter 105, Motor Current, is set for the full-load nameplate
motor current.
