Receiving & Inspection Baldor products are thoroughly tested at the factory and carefully packaged for shipment.
When you receive the BPS, there are several things you should do immediately.
1. Observe the condition of the shipping container and report any damage
immediately to the commercial carrier that delivered the product.
2. Remove the BPS from the shipping container and remove all packing materials.
The container and packing materials may be retained for future shipment.
3. Verify that the part number of the BPS you received is the same as the part
number listed on your purchase order.
4. Inspect the BPS for external physical damage that may have been sustained
during shipment and report any damage immediately to the commercial carrier.
5. If the BPS is to be stored for several weeks before use, be sure that it is stored
in a location that conforms to published storage humidity and temperature
specifications stated in this manual.
Location Considerations The location of the BPS is important. Installation should be in an area that is protected
from direct sunlight, corrosives, harmful gases or liquids, dust, metallic particles, and
vibration. Exposure to these can reduce the operating life and degrade performance.
Several other factors should be carefully evaluated when selecting a location for
installation:
1. For effective cooling and maintenance, the BPS should be mounted on a
smooth, non-flammable vertical surface.
2. At least 0.6 inches (15mm) top and bottom clearance must be provided for air
flow. Refer to Section 7 for mounting dimensions.
3. Altitude derating. Up to 3300 feet (1000 meters) no derating required. Derate
the continuous and peak output current by 1.1% for each 330 feet (100 meters)
above 3300 feet.
4. Temperature derating. From 5°C to 40°C ambient no derating required.
Above 40°C, derate the continuous and peak output current by 2.5% per °C
above 40°C. Maximum ambient is 50°C.
BPS LEDs’The system troubleshooting procedures involves observing the status of the “Ready”
LED, the “DB On”LED and the “Monitor”7 segment display. Table 2-1 provides
information related to the indications provided by these devices.
The DB LED is on whenever Dynamic Brake power is dissipated into the optional DB
(Dynamic Brake) resistor.

2-2 Installation MN1221
Mechanical Installation The BPS must be securely fastened to the mounting surface by the BPS mounting holes.
The location of the mounting holes is shown in Section 3 of this manual.
Electrical Installation All interconnection wires between the BPS, control, AC power source, motor, host control
and any operator interface stations should be in metal conduits. Use listed closed loop
connectors that are of appropriate size for wire gauge being used. Connectors are to be
installed using crimp tool specified by the manufacturer of the connector. Only class 1
wiring should be used.
System Grounding The BPS is designed to be powered from standard three phase lines that are electrically
symmetrical with respect to ground. System grounding is an important step in the overall
installation to prevent problems. The recommended grounding method is shown in
Figure 2-1 and 2-2.

System Grounding Continued
Ungrounded Distribution System
With an ungrounded power distribution system it is possible to have a continuous current
path to ground through the MOV devices. To avoid equipment damage, an Isolation
transformer with a grounded secondary is recommended. This provides three phase AC
power that is symmetrical with respect to ground.
Input Power Conditioning
The BPS is designed for direct connection to standard three phase lines that are
electrically symmetrical with respect to ground. Certain power line conditions must be
avoided. An AC line reactor or an isolation transformer may be required for some power
conditions.
SIf the feeder or branch circuit that provides power to the BPS has permanently
connected power factor correction capacitors, an input AC line reactor or an
isolation transformer must be connected between the power factor correction
capacitors and the BPS.
SIf the feeder or branch circuit that provides power to the BPS has power factor
correction capacitors that are switched on line and off line, the capacitors must
not be switched while the BPS is connected to the AC power line. If the
capacitors are switched on line while the BPS is still connected to the AC power
line, additional protection is required. TVSS (Transient Voltage Surge
Suppressor) of the proper rating must be installed between the AC line reactor
or an isolation transformer and the AC input to the BPS.
Line Impedance The BPS requires a minimum 3% line impedance. If the impedance of the incoming
power does not meet the requirement for the BPS, a 3 phase line reactor can be used to
provide the needed impedance in most cases. Line reactors are optional and are
available from Baldor.
The input impedance of the power lines can be determined as follows:
Measure the line to line voltage at no load and at full rated load.
Use these measured values to calculate impedance as follows:
%Impedance +(VoltsNo Load Speed *VoltsFull Load Speed)
(VoltsNo Load Speed) 100
Line Reactors Three phase line reactors are available from Baldor. The line reactor to order is based on
the full load current of the motor (FLA). If providing your own line reactor, use the
following formula to calculate the minimum inductance required.
L+(VL*L 0.03)
(I 3
Ǹ 377)
Where: L Minimum inductance in Henries.
VL-L Input volts measured line to line.
0.03 Desired percentage of input impedance.
I Input current rating of BPS.
377 Constant used with 60Hz power.
Use 314 if input power is 50Hz.

2-4 Installation MN1221
Power Disconnect A power disconnect should be installed between the input power service and the BPS for
a fail safe method to disconnect power. The BPS will remain in a powered-up condition
until all input power is removed from the BPS and the internal bus voltage is depleted.
Protection Devices The AC input power lines must have suitable protection devices installed. Input and
output wire size is based on the use of copper conductor wire rated at 75 °C. Use the
recommended circuit breaker or fuse types as follows:
Circuit Breaker: 1 phase, thermal magnetic.
Equal to GE type THQ or TEB for115 or 230 VAC
3 phase, thermal magnetic.
Equal to GE type THQ or TEB for 230 VAC or
GE type TED for 460 VAC.
Fast Action Fuses: Buss KTN on 230 VAC or
Buss KTS on 460 VAC, Buss FRS or equivalent.
Time Delay Fuses: Buss FRN on 230 VAC or
Buss FRS on 460 VAC or equivalent.
Table 2-2 describes the wire size to be used for power connections and the ratings of the
protection devices.
Recommended fuse sizes are based on the following:
115% of maximum continuous current for time delay fuses.
150% of maximum continuous current for fast or very fast acting fuses.

General Information
2-8 Installation MN1221
Optional I/O Connections Connector X4 contains the input and output connections for the BPS (Baldor Power
Supply). Connection to the X4 I/O terminal strip is optional. No connections are required
for normal operation. However, to monitor BPS status or to “Reset”the BPS you may
make some or all of these optional connections.
Status monitor output connections (Opto Isolated Outputs)
Status monitor output connections are shown in Figure 2-7. The output signals (X4-1, 2
and 3) can then be connected to an external device (referenced to X4-10). These internal
contacts close when active and apply the voltage +24VDC at the output.
The Alarm Output (X4–2) activates immediately when one of the following faults occur:
Loss of AC Power, Phase Loss (AC input), Loss of Logic Power, Bus Undervoltage,
Overtemperature or Dynamic Brake fault. The other Status Monitor outputs (X4–1 and 3)
have a 100ms delay before activation.
Note: The maximum current draw when all three outputs are active must not exceed
100mA.
