Installation
Mounting
• Drive components are sensitive to electrostatic discharge. Avoid direct contact with the circuit
• board. Hold the drive by the chassis only.
• Protect the drive from dirt, moisture, and accidental contact.
• Provide sufficient room for access to the terminal block 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 0.19" (5 mm) wide slots
• in the chassis accept #8 pan head screws. Fasten either the large base or the narrow flange of the
• chassis to the subplate.
• The chassis should be earth grounded. Use a star washer beneath the head of at least one of the
• mounting screws to penetrate the anodized chassis surface and to reach bare metal.
Wiring
Use 18 - 24 AWG wire for logic wiring.
Use 14 - 16 AWG wire for AC line (L1, L2) and motor (A1, A2) 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. Refer to
the user's manual for details on earth grounding shielded wires and filtering.
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
Armature
• 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
Range
• Electrical Code and all other applicable electrical and safety codes, including the provisions of the
• Occupational Safety and Health Act (OSHA), when installing equipment.
5.0 1/8 - 1/2
• Circuit potentials are at 115 above earth ground. Avoid direct contact with the printed circuit board
• or with circuit elements to prevent the risk of serious injury or fatality. Use a non-metallic
5.0 1/4 - 1
• 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, 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
• switch contacts should be rated for 250 VAC and 200% of motor nameplate current.
• Removing AC line power is the only acceptable method for emergency stopping. Do not use
• regenerative braking, decelerating to minimum speed, or coasting to a stop for emergency stopping.
• 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.
Line Input
Connect the AC line power leads to terminals L1 and L2. ACE recommends the use of a double-pole,
single throw master power switch. The switch should be rated at a minimum of 250 VAC and 200% of
motor current.
Motor
Connect the DC armature leads to terminals A1 and A2. If the motor does not spin in the desired
direction, power down the drive and reverse these connections.

Connections
Speed Potentiometer
Use a 50K ohm, 1/4 W potentiometer for speed control. Connect the counter-clockwise end of the
potentiometer to S0, wiper to S2, and the clockwise end to S1. 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 S0 and S1 connections. See the Operation section
for alternative wiring setups.
Regenerative Brake
Short terminals S0 and RB to regeneratively brake the motor to zero speed. The time it takes the motor
to come a stop is dependent on load inertia, friction, and the FWD TQ and REV TQ trim pot settings.
Open terminals S0 and RB to accelerate the motor to set speed.
Do not use the regenerative braking for emergency stopping.
