WARNING: Do not use motor overload relays with an automatic reset feature.
These are dangerous since the process may injure someone if a
sudden or unexpected automatic restart occurs. If manual reset
relays are not available, disable the automatic restart feature using
external control wiring.
WARNING: This unit has an automatic power up start feature that will start the
motor whenever input power is applied and a RUN (FWD or REV)
command is issued and maintained. If an automatic power up start
of the motor could cause injury to personnel, this feature should be
turned off.
WARNING: Be sure the system is properly grounded before applying power. Do
not apply AC power before you ensure that grounds are connected.
Electrical shock can cause serious or fatal injury.
WARNING: Do not remove cover for at least five (5) minutes after AC power is
disconnected to allow capacitors to discharge. Electrical shock can
cause serious or fatal injury.
WARNING: Motor circuit may have high voltage present whenever AC power is
applied, even when motor is not rotating. Electrical shock can
cause serious or fatal injury.
WARNING: Dynamic brake resistors may generate enough heat to ignite
combustible materials. Keep all combustible materials and
flammable vapors away from brake resistors.
Caution: Suitable for use an a circuit capable of delivering not more
than 5,000 RMS symmetrical amperes, at rated voltage.
Caution: Disconnect motor leads (T1, T2 and T3) from control before
you perform a “Megger” test on the motor. Failure to
disconnect motor from the control will result in extensive
damage to the control. The control is tested at the factory for
high voltage / leakage resistance as part of Underwriters
Laboratories Inc. requirements.
Caution: Do not connect AC power to the Motor terminals T1, T2 and

Section 3
Receiving and Installation
3-1 Receiving and Installation MN715P
Receiving & Inspection
The Series 15P Inverter control is thoroughly tested at the factory and
carefully packaged for shipment. When you receive your control, 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 your control.
2. Verify that the control you received is the same as listed on your
purchase order.
3. If the control is to be stored for several weeks before use, be sure that it
is stored in a location that conforms to published storage specifications.
(Refer to Section 6 of this manual).
Physical Installation
The mounting location is important. The control should be installed in an area
that is protected from direct sunlight, corrosives, harmful gases or liquids,
dust, metallic particles and vibration. Exposure to these elements can reduce
the operating life and degrade performance of the control.
Several other factors should be carefully evaluated when selecting a location
for installation:
1. For effective cooling and maintenance, the control should be mounted
on a smooth, non-flammable vertical surface. Table 3-1 lists the Watts
Loss ratings for enclosure sizing.
2. Provide at least two inches of clearance on all sides for airflow.
3. Front access must be provided to allow the control cover to be opened
or removed for service and to allow viewing of the Keypad LEDs.
4. Altitude derating. Up to 3300 feet (1000 meters), no derating is
required. Above 3300 feet, derate peak or continuous output current by
2% for each 1000 feet above 3300 feet.
5. Temperature derating. Up to 40°C, no derating is required. Above
40°C, derate peak or continuous output current by 2% per °C above
40°C.
Maximum ambient is 55°C.

Control Installation
The control must be securely fastened to the mounting surface. Use the four
(4) mounting holes to fasten the control to the mounting surface or enclosure.
Shock Mounting
If the control will be subjected to levels of shock greater than 1G or vibration
greater than 0.5G at 10 to 60Hz, the control should be shock mounted.
Excessive vibration within the control can cause internal connections to
loosen and could lead to component failure or electrical shock hazard.

MN715P Receiving and Installation 3-2
Electrical Installation
Interconnection wiring is required between the motor control, AC power
source, motor, host control and any operator interface stations. Use UL listed
closed loop connectors that are of an appropriate size for the 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
Baldor controls are 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.

AC Line Connections
A power disconnect should be installed between the input power service and
the control for a fail-safe method to disconnect power. The control will remain
in a powered-up condition until all input power is removed from the control and
the internal bus voltage is discharged.
Protective Devices
Recommended fuse sizes are based on the following:
115% of maximum continuous current for time delay.
150% of maximum continuous current for Fast or Very Fast action.
Note: These general size recommendations do not consider harmonic currents or
ambient temperatures greater than 40°C.
Be sure a suitable input power protection device is installed. Use the
recommended fuses listed in Tables 3-4 and 3-5 (Wire Size and Protection
Devices). Input and output wire size is based on the use of copper conductor
wire rated at 75 °C. The table is specified for NEMA B motors.

For motors with spring set brakes, connect the brake power leads and the
motor power leads separately. Because the inverter has variable voltage
output to the motor, the inverter may not supply enough power at low
frequencies for proper brake operation. If using a motor with an internally
connected brake, the brake power leads must be connected to a separate
power source for proper brake operation. Refer to Figure 3-2 for terminal
locations.
Optional Dynamic Brake Hardware
Dynamic Brake (DB) Hardware must be installed on a flat, non-flammable,
vertical surface to obtain effective cooling and operation. The ambient
temperature must not exceed 80°C. DB connections are shown in Figure 3-6.

General Machinery Load Calculations:
1. Calculate braking duty cycle:
Duty Cycle +Braking Time
Total Cycle Time
2. Calculate deceleration torque:
TDecel +RPM change Wk2
308 time *Friction(Lb.Ft.)
where: TDecel = Deceleration torque in lb-ft.
Wk2= Inertia in lb-ft2
time = In seconds
3. Calculate watts to be dissipated in dynamic braking resistor:
Watts +TDecel ǒSmax *SminǓ Duty Cycle (0.0712)
where: Smax = Speed to start braking
S
min = Speed after braking
4. Multiply watts calculated in step 3 by 1.25 to allow for unanticipated
loads (safety factor).

Analog Input
(S1-7 = OFF)
If S1-7 is OFF, the front panel % Speed potentiometer is selected. The J4
inputs are ignored.
(S1-7 = ON)
One analog input is available at J4-2 and J4-1 as shown in Figure 3-7. The
input may be connected to a potentiometer as shown or an input signal can be
applied to pin J4-2. The analog signal can be 0-10VDC or 4-20 mA as
selected by S1−6 (see Table 3-6).
Note: A potentiometer value of 5kto 10k, 0.5 watt may be used.

(S1-8 = OFF)
If S1-8 is OFF, the front panel commands FWD, REV and STOP are selected.
The J4 inputs are ignored.
(S1-8 = ON)
Three inputs are available on the J4 connector. Switch S1-5 determines
whether two wire or three wire operation is used. If two wire is selected
(S1-5= OFF) the STOP input at J4-6 is not used.
Note: Pressing the STOP switch on the front panel keypad will override the J4
commands and cause the motor to decel to a stop.
