1-8 General Information
Section 2
Installation
This section describes the proper mounting and wiring of the
BALDOR Series 10 Inverter. If problems arise, please refer to
the troubleshooting information located in Section 4.
Location and Mounting
Select a mounting surface for the inverter that will allow the
control to be mounted in a vertical position using the four
mounting holes provided. The area selected should allow for
free air circulation around the control. Provide for at least five
inches of clearance on all sides for maximum cooling efficiency.
Caution: Avoid locating the inverter immediately
above or beside heat generating equipment,
or directly below water or steam pipes.
The ambient temperature around the control should not exceed
40°C. If the control is mounted into an existing control cabinet,
the ambient temperature limits should not be exceeded or failure
of the control may result. In cases where extreme temperatures
are unavoidable, a separate blower fan or cooling system should
be considered. Please contact the factory for derating of
controls operated in temperatures above 40°C.
The standard ventilated NEMA 1 enclosure should not be used
in areas where the control will be subjected to liquids, chemicals,
large amounts of airborne material (i.e. dust or lint), or explosive
atmospheres. Appropriate protection should be provided for the
inverter when used in these environments.
If the control will be subjected to levels of vibration above 0.6G,
then the inverter should be shock mounted. Excessive vibration
within the control could cause internal connections to loosen and
cause component failure or electrical shock hazard.
Installation 2-1
Terminal Access Cover Removal
To remove the Terminal Access Cover insert a small blade
screwdriver into the slots located on the lower left and right hand
corners of the access cover. Use a slight twisting motion while
lifting upward to loosen one side. Use the same motion to
loosen the other side then lift the cover off of the control. To
reinstall, simply snap the cover back into place. See Figure 2-1
below.
Figure 2-1
2-2 Installation
Terminal and Jumper Locations
Figure 2-2 shows the location of the power terminal strip , control
terminal strip , ground lug, and user adjustable jumper locations.
Only motor and input power should be connected to the power
terminal strip. Motor ground and input power earth ground
should be connected to the ground lug. Only external control
wiring should be connected to control terminal strip.

Wiring Considerations
Interconnection wiring is required between the motor control, AC
power source, motor, host control and any operator interface
stations. 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.
Installation 2-3
Caution: Separate over-current protection may be
required by the National Electrical Code. The
installer of this equipment is responsible for
complying with the National Electrical Code
and any applicable local codes which govern
such practices as wiring protection,
grounding, disconnects, and other current
protection.
The inverter is self protected from normal AC line transients and
surges. Additional external protection may be required if high
energy transients are present on the incoming power source.
These transients could be caused by sharing a power source
with arc welding equipment, large motors being started across
the line, or other industrial equipment requiring large surge
currents. To prevent inverter damage due to power source
disturbances the following should be considered:
1. Connect the inverter on a feeder line separate from those
supplying large inductive loads.
2. Supply power to the inverter through a suitably sized
isolation transformer. When using an isolation transformer
to power the inverter, always switch the power off and on
between the transformer secondary and the inverter input to
avoid spikes at the inverter when power is removed from
the primary side.
3. Supply power to the inverter through a suitably sized line
reactor. Line reactors serve several purposes:
4.
A. Minimize voltage spikes from the power line that may
cause the inverter to trip on over-voltage.
B. Minimize voltage harmonics from the inverter to the
power line.
C. Provide additional short circuit capability at the inverter.
2-4 Installation
Caution: Do not use power factor correction
HP
Breaker
capacitors on the input power lines to the
inverter or damage to the control may result.
All external control wiring to the inverter should be run in a
separate conduit from all other wiring. The use of shielded
twisted pair wire is recommended for all control wiring. The
shield of the control wiring should be connected to control
terminal CM of the inverter only. The other end of the shield
should be taped to the wire jacket to prevent electrical shorts.
Conduit openings are provided at the bottom of the inverter
housing to allow power and control wiring entrance to the control.
Please refer to the inverter outline drawings located in Section 5
of this manual for sizes of the conduit openings.
The following tables show recommended wire size and
protection devices along with recommended terminal tightening
torques.

2-6 Installation
AC Power Connections
Connect the fused three phase AC power lines to the input
power terminals L1, L2, and L3. The phase rotation of the input
power is not important since the control is not sensitive to phase
rotation of the input power. For single phase AC power connect
to input power terminals L1 and L2.
Connect an earth ground to the inverter according to any
applicable electrical code. The earth ground should be
connected to the inverter chassis ground screw.
The use of a power disconnect is recommended between the
input power and the inverter to provide a fail safe method to
disconnect the inverter from the input power. The inverter will
remain in a power up condition until all input power is removed
from the control and the internal bus voltage is depleted.
Caution: Do not attempt to service this equipment
while bus voltage is present within the
inverter. Remove input power and wait at
least 5 minutes for the residual power in the
bus capacitors to dissipate.
Caution: This unit has an automatic restart feature
that will start the motor whenever input
power is applied and a maintained external
run (FWD or REV) command is present at the
control. If an automatic restart of the motor
could cause personal injury or harm, the
auto restart feature should be defeated with
external control wiring or by adjusting
parameter 82-Start Options.
Installation 2-7
Motor Connections
Connect the three phase power leads of the AC motor to
terminals M1, M2, and M3 of the inverter power terminal strip.
The motor ground lead or case ground should be connected to
the inverter chassis ground screw. The motor should be
connected to the inverter at all times during inverter operation.
If additional motor overload protection is required, the use of
suitably sized motor overload relays are recommended. Motor
overload relays should be connected between the motor and
inverter with the relay trip indicator circuit connected into the
external inverter control circuitry to power down or trip the
inverter in the event of motor overloading.
Caution: Overload relays with an automatic reset
feature are not recommended in applications
where an automatic restart of the motor
could cause personal injury or harm. If
manual reset relays are not available, then
the automatic reset feature should be
defeated.
If the motor is equipped with a normally closed thermostat, the
thermostat should be connected at terminals MOL and CM of the
control terminal strip. The inverter will also need to be
programmed to trip if this thermostat circuit opens indicating a
motor overload condition. The inverter will need to be
programmed by adjusting parameter 77-External Trip Select and
placing the proper jumper position on jumper terminals J19.
If during initial motor start up the motor rotation is opposite to
that desired, disconnect the input power from the inverter and
wait at least 5 minutes for the bus voltage to bleed off.
Interchange any two of the three motor leads at the inverter
power terminal strip M1, M2, and M3 to change the shaft rotation
of the motor.
2-8 Installation
M-Contactor
If required by local codes or for safety reasons, an M-Contactor
(motor circuit contactor) may be installed. However, incorrect
installation or failure of the M-Contactor or wiring may damage
the control.
Caution: If an M-Contactor is installed, the control
must be disabled at least 20msec before the
M-Contactor is opened. If the M-Contactor is
opened while the control is supplying
voltage and current to the motor, the control
may me damaged.
A motor circuit contactor provides a positive disconnect of the
motor windings from the control. Opening the M-Contactor
ensures that the control cannot drive the motor. This may be
required during certain manual operations with the load (like
cleaning cutting knives etc.). Figure 2-3 shows how an
M-Contactor is connected to the H series control.

Logic Wiring
All logic and control connections are made at the control terminal
strip located on the motor control board. Screw type terminals
are provided for easy connection to your external control station
and meters. The control terminal strip can be divided into four
major categories as follows:
1) Analog command inputs.
2) Analog outputs.
3) Opto Isolated inputs.
4) Relay outputs.
Analog Command Inputs
An external 5kohm potentiometer can be connected at terminals
CM, VIN, and REF. The potentiometer should be connected so
that full resistance is connected from CM and REF. REF is a
5VDC potentiometer reference output. The wiper of the
potentiometer should be connected at terminal VIN. The speed
command input will be recognized at terminals CM and VIN.
When using a potentiometer as the speed command, the Analog
Command Select parameter will need to be programmed to 0 or
1 and jumper J19 will need to be set properly.
An external speed command of 0-5VDC, 0-10VDC, 0-20 mA, or
4- 20mA can be used instead of a potentiometer at terminals CM
and VIN. The positive lead should be connected at terminal VIN
and the negative lead should be connected at terminal CM. The
Analog Command Select parameter should also be programmed
to 0 or 1 and jumper J19 will need to be set properly.
