Installation
Mounting
• Drive components are sensitive to electrostatic discharge. Avoid direct contact with the circuit
• board. Hold the drive by the plate only.
• Protect the drive from dirt, moisture, and accidental contact.
• Provide sufficient room for access to the terminals and calibration trim pots.
• Mount the drive away from heat sources. Operate the drive within the specified ambient operating
• temperature range.
• Prevent loose connections by avoiding excessive vibration of the drive.
• Mount the drive with its board in either a horizontal or vertical plane. Six 0.17" (4 mm) holes in the
• plate accept #8 pan head screws. If mounted horizontally, the drive must be de-rated to 3.0 amps.
• The plate should be earth grounded.
Wiring
Use 18 - 24 AWG wire for logic wiring. Use 14 - 16 AWG wire for AC line and motor wiring.
Shielding Guidelines
As a general rule, ACE recommends shielding of all conductors. If it is not practical to shield power
conductors, ACE recommends shielding all logic-level leads. If shielding of logic-level leads is not
practical, the user should twist all logic leads with themselves to minimize induced noise. It may be
necessary to earth ground the shielded cable. If noise is produced by devices other than the drive,
ground the shield at the drive end. If noise is generated by the drive, ground the shield at the end
away from the drive. Do not ground both ends of the shield.
Fusing
ACE drives require an external line fuse for protection. Use fast acting fuses rated for 250 VAC or
higher and 150% of the maximum armature current. Fuse the HOT leg of the AC line when using 115
VAC and both lines when using 230 VAC.

READ ALL SAFETY WARNINGS BEFORE INSTALLING THIS EQUIPMENT
Continuous
• DO NOT INSTALL, REMOVE, OR REWIRE THIS EQUIPMENT WITH POWER APPLIED. Have a
Armature Horsepower
• qualified electrical technician install, adjust and service this equipment. Follow the National
Current (Amps) Range
• Electrical Code and all other applicable electrical and safety codes, including the provisions of the
1/20 - 1/3
• Occupational Safety and Health Act (OSHA), when installing equipment.
1/20 - 1/2

• Circuit potentials are at 115 or 230 VAC above earth ground. Avoid direct contact with the printed
1/10 - 2/3
• circuit board or with circuit elements to prevent the risk of serious injury or fatality. Use a non-
1/10 - 3/4 • metallic screwdriver for adjusting the calibration trim pots. Use approved personal protection
• equipment and insulated tools if working on this drive with power applied.
• Reduce the chance of an electrical fire, shock, or explosion by using proper grounding techniques,
• over-current protection, thermal protection, and enclosure. Follow sound maintenance procedures.
• ACE strongly recommends the installation of a master power switch in the line voltage input. The
..........................0.5 - 11 seconds • switch contacts should be rated for 250 VAC and 200% of motor nameplate current.
........................0.5 - 20 seconds • Removing AC line power is the only acceptable method for emergency stopping. Do not use
.........................0.5 - 11 seconds • regenerative braking, decelerating to minimum speed, or coasting to a stop for emergency stopping.
.......................0.5 - 20 seconds • They may not stop a drive that is malfunctioning. Removing AC line power is the only acceptable
• method for emergency stopping.
• Line starting and stopping (applying and removing AC line voltage) is recommended for infrequent
• starting and stopping of a drive only. Regenerative braking, decelerating to minimum speed, or
• coasting to a stop is recommended for frequent starts and stops. Frequent starting and stopping can
• produce high torque. This may cause damage to motors.
• Do not disconnect any of the motor leads from the drive unless power is removed or the drive is
• disabled. Opening any one lead while the drive is running may destroy the drive.
• Under no circumstances should power and logic level wires be bundled together.
• Be sure potentiometer tabs do no make contact with the potentiometer's body. Grounding the
• input will cause damage to the drive.
• Only connect to terminal L2-DBL if using a 115 VAC line with a motor rated higher than 130 VDC.
Line Input
If using a 115 VAC line with a 90/130 VDC motor or a 230 VAC line with a 90/130/180/240 VDC motor,
connect to terminals L1 and L2. If using a 115 VAC line with a 180/240 VDC motor, connect to terminals
L1 and L2-DBL. ACE recommends the use of a double-pole, single-throw master power switch. The
switch should rated at a minimum of 250 VAC and 200% of motor current.
Motor
Connect the DC armature leads to terminals U/A2 and V/A1. If the motor does not spin in the desired
direction, power down the drive and reverse these connections.

LOGIC (TOP BOARD)
Speed Potentiometer
Use a 10K ohm, 1/4 W potentiometer for speed control. Connect the counter-clockwise end of the
potentiometer to S1, wiper to S2, and the clockwise end to S3. If the potentiometer works
inversely of desired functionality, (i.e. to increase motor speed, you must turn the potentiometer
counterclockwire), power off the drive and swap the S1 and S3 connections.
Analog Input Signal Range
Instead of using a speed adjust potentiometer, PMB703 series drives may be wired to follow an
analog input signal. This input signal can be in the form of voltage (0-5, 0 to ±10 VDC) or current
(4-20 mA). Because these drives have built in isolation, the input signal can be grounded or
ungrounded (floating). Connect the signal common (-) to S1 and the signal reference (+) to S2. See the
Operations section for jumper settings.
Enable
ENABLE
Short terminals EN and COM to accelerate the motor to set speed. Open the ENABLE terminals to coast
SWITCH
the motor to zero speed. If no ENABLE switch is desired, wire a jumper between terminals COM and EN.
Do not use the enable for emergency stopping.
Direction
Short terminals DIR and COM to change the direction of the motor. If no direction switch is desired,
leave this connection open.
