ACE recommends the use of a double-pole, single-throw master power switch.

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 orungrounded (floating). Connect the signal common (-) to S1 and the signal reference (+) to S2. See theOperations section for jumper settings.EnableShort terminals EN and COM to accelerate the motor to set speed. Open the ENABLE terminals to coastthe 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.DirectionShort terminals DIR and COM to change the direction of the motor.

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.WiringUse 18 - 24 AWG wire for logic wiring. Use 14 - 16 AWG wire for AC line and motor wiring.Shielding GuidelinesAs a general rule, ACE recommends shielding of all conductors. If it is not practical to shield powerconductors, ACE recommends shielding all logic-level leads. If shielding of logic-level leads is notpractical, the user should twist all logic leads with themselves to minimize induced noise. It may benecessary 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 endaway from the drive. Do not ground both ends of the shield.FusingACE drives require an external line fuse for protection. Use fast acting fuses rated for 250 VAC orhigher and 150% of the maximum armature current. Fuse the HOT leg of the AC line when using 115VAC and both lines when using 230 VAC.Safety Warnings• DO NOT INSTALL, REMOVE, OR REWIRE THIS EQUIPMENT WITH POWER APPLIED. Have a• qualified electrical technician install, adjust and service this equipment. Follow the National• Electrical Code and all other applicable electrical and safety codes, including the provisions of the• Occupational Safety and Health Act (OSHA), when installing equipment.• Circuit potentials are at 115 or 230 VAC 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 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• 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.• Only connect to terminal L2-DBL if using a 115 VAC line with a motor rated higher than 130 VDC.READ ALL SAFETY WARNINGS BEFORE INSTALLING THIS EQUIPMENT1/20 - 1/31/20 - 1/21/10 - 2/31/10 - 3/4HorsepowerRange3.6*ContinuousArmatureCurrent (Amps)0 - 900 - 1300 - 1800 - 240ArmatureVoltage Range(VDC)115or230LineVoltage(VAC)PMB703-3ModelSpecifications......................................................115/230 VAC ± 10%, 50/60 Hz, single phase..........................................................................................................................1.05..........................0.5 - 11 seconds........................0.5 - 20 seconds.........................0.5 - 11 seconds.......................0.5 - 20 seconds........................................................0 - 5; 0 to ± 10 VDC........................................................................4 - 20 mA.......................................................................................>50K ohms...................................................................................1% base speed or better.......................................................................................................................100:1...........................................................................................0.5G maximum..............................................................................................0.1G maximum.....................................................................................0°C - 40°C..............................................................................................................................1.1 lbsAC Line VoltageForm FactorAcceleration Time Range for 90 / 130 VDC armature voltagefor 180 / 240 VDC armature voltageDeceleration Time Range for 90 / 130 VDC armature voltagefor 180 / 240 VDC armature voltageAnalog Input Voltage Range (S1 to S2)Analog Input Current Range (S1 to S2)Input Impedance (S1 to S2)Load RegulationSpeed RangeVibration (0 - 50 Hz)(>50 Hz)Ambient Temperature RangeWeight* When mounted vertically.
