Safety Warnings
READ ALL SAFETY WARNINGS BEFORE INSTALLING THIS EQUIPMENT
•
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 installed 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 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
•
DC injection 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. DC injection 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 enclosure. Grounding the
•
input will cause damage to the drive.
• Caution should be taken when operating fan-cooled motors at low speeds because their fans may
•
may not move sufficient air to properly cool the motor. American Control Electronics recommends
•
“inverter-duty”
motors when the speed range is beyond 10:1.
• Drive is designed to work with permanent split capacitor, shaded pole, and standard three phase
•
induction motors. In general, the drive can work with capacitor-start motors, but it is conditional
•
on the current pull when the capacitor is in effect and how long the application calls for a speed that
•
the capacitor will stay in the auxiliary winding. It is recommended to contact the motor manufacturer
•
to see if the motor can be ran with a VFD.

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 0.20” (5 mm) wide slots
•
in the chassis accept #8 pan head screws.
• 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 and motor wiring.
Shielding Guidelines
As a general rule, it is recommended to shield all conductors. If it is not practical to shield power
conductors, it is recommended to shield 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
The 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.
Connections
Line Input
Connect the AC line power leads to terminals L1 and L2 ACE recommends the use of a
single-throw, double-pole master power switch. The switch should be rated at a
minimum of 125 VAC and 200% of motor current.
Motor
If using a three phase motor, connect the AC motor leads to terminals U, V, and W. If
the motor does not spin in the desired direction, power down the drive and swap any
two of these connections. If using a single phase motor, connect the AC motor leads to
terminals U and V. Refer to the Operations section for possible wiring setups.

LINE INPUT
Speed Potentiometer or Analog Input Signal
Use a 10K ohm, 1/4 W potentiometer for speed control. Connect the counter-clockwise end of the potentiometer to
S1, the wiper to S2, and the clockwise end to S3. If the potentiometer works inveresly of desired functionality, (i.e. to
increase motor speed, you must turn the potentiometer counterclockwise), power off the drive and swap the S1 and S3
connections. The drive may also follow a 0-5 VDC analog signal that is isolated from earth ground. Connect the signal
common to terminal S1 and the signal input to terminal S2.
Direction Switch
If a direction switch is desired, wire a switch to terminals E1 and DIR. When the connection is open, the motor will run in
the forward direction. When the connection is closed, the motor will run in reverse. If no direction switch is desired,
leave this connection open.
Enable
Open the terminals E1 and E2 to coast the motor to minimum speed. Close terminals E1 and E2 to accelerate the motor
to set speed. If no enable switch is desired, jumper terminals E1 and E2.
Do not use the enable for emergency stopping.
