2. Avoid running signal leads in close proximity to
power leads, motor stator leads, or other sources
of electromagnetic noise. Run signal leads in
separate conduit from power leads. Shields are
recommended for signal leads.
3. Minimize lead lengths.
4. Connect the BDS5 system according to the
System Wiring Diagram, A-93103; pay close
attention to the grounding scheme and notes.
2.6.1 Wiring the Ground
Ground terminals are provided on the front of BDS4's,
BDS5's, and PSR4/5's. These ground screws are
directly below the Power Terminal Block of each unit.
To prevent shock hazard and to ensure proper
operation of the system, the BDS5, PSR4/5, and the
motor must be grounded. Each BDS5 and PSR4/5 has
two ground screws on the front of its chassis.
GROUND YOUR BDS5,
PSR4/5, and motor
PROPERLY! Failure to
provide proper grounding can
result in a shock hazard.
One of the ground screws on the PSR4/5 should be
connected to Earth Ground or Machine Ground. The
other should be connected to the adjacent BDS5
ground screw, along with the ground wire from the
motor. The other ground screw on the BDS5 chassis
should then be connected to the next BDS5, etc. Use
10 AWG or larger wire for grounding between BDS5's
and PSR4/5's and from PSR4/5 to Earth Ground or
Machine Ground.
2.6.2 Wiring the Power Connections
This section discusses how to wire the PSR4/5 and
BDS5 power connections.
To prevent equipment
damage, the AC Line and the
DC bus must be connected as
indicated by the System
Wiring Diagram, A-93103.
The PSR4/5 and BDS5 are configured at the factory
for operation from either a 115 volt or a 230 volt AC
Line. The PSR4/5 and the BDS5 must both have the
same voltage rating. Operating a PSR4/5 or a BDS5
with incorrect voltage can damage the units.
Use the proper AC Line
voltage. PSR4/5's and BDS5's
are configured at the factory
for 115 volt or 230 volt AC
Line voltage. See the model
number description at the
beginning of this chapter to
determine the required
voltage for your PSR4/5 and
BDS5.
2.6.2.1 Wiring the Motor
Connect Pins A, B, and C of the motor connector
through a motor cable to Ma, Mb, and Mc,
respectively, on the Power Terminal Block located on
the front of the BDS5 amplifier. Connect Pin D of the
motor connector through the same motor cable to the
BDS5 chassis ground screw located directly beneath
the Power Terminal Block.
IT IS VERY IMPORTANT THAT YOU WIRE THE
MOTOR PROPERLY. Brushless permanent magnet
motors are not like induction motors. You cannot
simply interchange two phases to reverse the direction
of rotation.
Standard Industrial Drives motor cable has the color
code as shown in Table 2.1.

Incorrect motor wiring can
cause erratic or runaway
motor operation. Use of
factory supplied cable sets is
highly recommended.
