PRODUCT SPECIFICATIONS
ABOUT THIS PRODUCT - Bodine’s PACESETTERTM “NEMA 4” series
inverter is designed to provide variable speed control of standard three-
phase AC induction motors. Adjustable linear acceleration and
deceleration are provided, making the drive suitable for soft start
applications. The output voltage is sinewave coded PWM operating at 16
kHz, which provides high motor torque, high efficiency, and low noise.
The full featured drive is easy to install and operate. Simple trimpot
adjustments eliminate the computer-like programming required on other
drives. However, for most applications, no adjustments are necessary.

IMPORTANT SAFETY PRECAUTIONS
Model 2995 has been evaluated by Underwriters Laboratories for conformance
to UL standards 508 and 50 and CSA standard C22.2 No. 14 and bears the UL
Recognized Component mark.
The AC Drive is a power electronic device. For safety reasons, please read
through this operations manual in detail and observe those paragraphs with the
safety alert symbol.
This is the safety alert symbol. It is used to alert you
to potential personal injury hazards. Obey all safety
messages that follow this symbol to avoid possible
injury or death.
WARNING
WARNING indicates a potentially hazardous
situation which, if not avoided, could result in
death or serious injury.
CAUTION
CAUTION indicates a potentially hazardous
situation which, if not avoided, may result in
minor or moderate injury.
CAUTION
CAUTION used without the safety alert
symbol indicates a potentially hazardous
situation which, if not avoided, may result in
property damage.
WARNING
Do not touch printed circuit board (PCB) right after
turning off power. Wait until power light turns off.
Do not attempt to wire circuitry while power is on.
Do not attempt to examine components and signals on
the PCB while the inverter is operating.
Do not attempt to disassemble or modify internal
circuitry, wiring, or components of the inverter.
Inverter must be properly grounded.

INSTALLATION
This control should only be installed by a qualified person familiar
with its operation and associated hazards. The National Electrical
Code (NEC), local electrical and safety codes, and when
applicable, the Occupational Safety and Health Act (OSHA) should
be observed to reduce hazards to personnel and property.
Step 1. Examine before installation
Check that the model number on the control matches the model number
ordered. The control model number is printed as part of the serial number on an
adhesive label on the outside bottom surface of the control enclosure. Carefully
examine the control for shipping damage. Parts errors should be reported to
Bodine. Shipping damage claims should be made to the freight carrier.
Figure 2 – The model number is the first four digits of the serial number
(S/N) on the control’s nameplate.
CAUTION
Do not connect the control to the power supply if there is
any sign of damage. Notify the carrier and your distributor
immediately.

Step 2. Choose a Suitable Location
The installation site directly impacts the functionality and lifespan of the control.
Avoid areas where surrounding air temperature exceeds 40OC (direct
sunlight or near heating equipment or inside a panel without a cooling fan.
Avoid locations where the front panel dial and switch may be bumped and
accidentally turned on/off or damaged.
Avoid environments with corrosive gas.
Avoid locations near radioactive matter or flammable material.
Avoid locations near equipment that generate electromagnetic interference
(soldering or power machinery).
Avoid mounting the control to a surface that vibrates.
Step 3 – Mount the
Control
Prepare the mounting surface by
drilling four holes with their
centers located as shown in
Figure 3. If #10 screws are to be
used for mounting, then use a #6
(.204) clearance drill. If #10-32
machine screws are to be used
for mounting, then use a #20
(.161) tap drill. After the
mounting surface has been
prepared, mount the control with
screws through the four
mounting brackets (already
attached to back of control
enclosure).

CONNECTION
CAUTION
The PCB inside the inverter enclosure is vulnerable to
static electrical charges. Avoid contact with the PCB.
Choose an appropriate power source with correct
voltage settings for the specification of the AC inverter.
Do not use a separate device between control and
motor to switch motor ON or OFF during operation.
Step 4 – Preliminary Setup
Figure 4 - Inside of control, showing location of jumpers and fuses.
BASE FREQUENCY JUMPER - Model
2995 is factory set to operate 60 Hz and
50/60 Hz motors. For 50 Hz motors,
remove jumper J1 on the lower printed
circuit board. When the control is set for
50 Hz operation, the DECEL/B trimpot
will automatically change to adjustable
boost. The control can also operate 60
Hz and 50/60 Hz motors (not 50 Hz
motors) in an over speed mode by
moving the jumper to the 120 Hz
position. Figure 5 - The different ways o
f
setting the base frequency jumper.
9
In this mode, the motor will produce full rated torque up to 60 Hz. Above 60 Hz,
torque will linearly reduce to 50% at 120 Hz.
Figure 6 - Graph showing reduction in motor torque at frequencies above 60 Hz.
AC LINE VOLTAGE SELECTOR JUMPERS – There are three voltage selector
jumpers that must be repositioned if the input line voltage is 230 VAC instead of
115 VAC. If the control is to be operated from a 230 VAC power supply, pull out
the voltage selector jumpers J1, J2, and J10 from their “115V” positions and
reinsert them into their “230V” positions. See Figure 4 for the locations of the
jumpers.
CAUTION
Connecting 230 VAC to a control configured for 115 VAC will
permanently damage the control.
AC LINE FUSE JUMPER WIRE – If the control is to be operated from a two-
phase 230 VAC power supply, where both lines are hot (typically in the USA),
then remove the jumper wire between the spades labeled “J5” and “J8.”
AC LINE FUSES – Model 2995 has a 12A fuse already installed in both the “F1”
and “F2” fuse holders. A fuse is only really necessary in “F2” if a two-phase 230
VAC power supply (with two hot sides) is used.

Step 5 – Connect the Motor
A cord should be used for the motor connection in order to properly seal the
liquid tight fitting. The fitting will accept cord diameters between 0.17” and 0.47”
diameter. The length of the cord should be kept short for minimum voltage drop
and only copper wire with 60OC rated insulation should be used. Loosen the nut
from the liquid tight fitting and insert the cord through the fitting and into the
enclosure. Connect the three motor power leads to “U”, “V”, and “W” on the
terminal block inside the control. Since the controls are capable of changing
motor direction electronically, it doesn’t really matter which motor wires go to
which terminal. However, if it is desired for the motor to rotate a specific
direction when wired a certain way, then refer to the connection diagrams for
Bodine inverter-duty motors in Figures 8 and 9 on the next page. If the motor
doesn’t rotate in the desired direction as connected, with reference to the
“forward” and “reverse” settings of the direction switch on Model 2995, then
swap any two of the three motor wires. Note that these connection diagrams
apply to Bodine motors only. The terminal block will accept wire sizes from 18 to
14 gauge. The terminal block screws should be tightened to 6 lb-in (0.678 Nm).
Connect the motor frame ground to “CHASSIS GROUND” on the terminal block.
When the connections are done, tighten the nut on the liquid tight fitting.
