Electrical Connections; Power Leads; Motor Protection - PowerTec Ferrite F Series Installation And Operation Manual

ELECTRICAL CONNECTIONS

All connections for the motor are in the main terminal box, except
on 320 frame and 500 frames. On these frames, the feedback
connections are in a separate conduit box.

POWER LEADS

The motor ships from the factory already connected for the
speed, voltage, and power listed on the nameplate. The correct
connection of the motor is shown on the nameplate as
"CONNECTION _ D _ Y". There will be a number "1" or "2"
in front of one of these symbols.

Possible motor connections.
Whatever the motor connections, you must connect the T1 motor
lead to the T1 or U terminal on the motor control. You must
connect the motor T2 to the T2 or V terminal on the motor control.
You must connect the motor T3 to the T3 or W terminal on the
motor control. Wire size must be based on the RMS current on
the nameplate of the motor. The motor may draw up to 150% of
this value for periods of up to one minute.
In addition to the wiring of T1, T2, and T3, you must install a
ground wire, which may be one size smaller than the power
leads. It must run from a ground bolt in the motor's junction box to
a ground bolt on the motor control. This ground wire is in addition
to required grounding of the motor to its frame.
Electrical connections to the motor must be tight and well insulated
from each other and from the frame.
NOTE: Drives with IGBT output devices generate higher
voltages at the motor terminals than are normally seen with
bipolar transistor types. Additional care must be taken in taping
and insulating of motor leads in the motor junction box.

MOTOR PROTECTION

POWERTEC Series motors come in two types:
Resolver type motors are equipped with an integral resolver
mounted in the rear of the motor (non-drive end), and with two
thermal switches in the windings. See page 3.
Encoder type motors are equipped with a hall-effect encoder
mounted in the non-drive end of the motor and a bi-metallic
thermal switch in the windings. See page 3.
Thermal switches may be used in separate control circuits up to
240 VAC. Failure to connect the motor protection properly may
result in damage to the motor, or drive, or both.
BLOWER MOTOR CONNECTIONS
Cooling blowers are supplied on DPBV and TEAO motors.

Blower motor connections are located in their own box on the
blower motor. Blowers will vary on non-standard motors.

WIRE COLOR:
Size 2 blowers are single phase, 115VAC. These motors are
impedance protected. Size 3 blowers supplied on 210T through
256T series motors are 3 phase, dual voltage design. For 200 or
230VAC input, they are connected in a delta configuration. For
380 or 460VAC operation they are connected in a star
configuration. Size 8, 9, and 10 blowers use standard AC motors.
They are dual voltage motors that operate on 208-230 or
460VAC. Special motors are supplied on 380VAC. Check blower
motor nameplate for rating data.
If starters, fuses and overloads are not supplied with a motor
control, blower motors must be supplied by proper disconnect
and protective devices.
