Installation
Mounting
• Drive components are sensitive to electrostatic discharge. Avoid direct contact with the circuit
• board. Hold the drive by the chassis or heat sink 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. Eight 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.
Heat Sinking
The PWM400-10 requires an additional heat sink when the continuous armature current is above 5
amps. Use ACE heat sink kit part number HSK-0001. Use a thermally conductive heat sink compound
(such as Dow Corning 340® Heat Sink Compound) between the chassis and the heat sink surface for
optimal heat transfer.
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.

• 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.
• 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.
Speed Potentiometer
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 inversely 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.
Inhibit
Short the INHIBIT terminals to coast the motor to zero speed. Open the INHIBIT terminals to
accelerate the motor to set speed. Twist inhibit wires and seperate them from power-carrying wires or
sources of electrical noise. Use shielded cable if the inhibit wires are longer than 18 inches (46 cm). If
shielded cable is used, ground only one end of the shield to earth ground. Do not ground both ends of
the shield. Do not use the inhibit for emergency stopping.
ACE offers two accessory plug harnesses for connecting to the inhibit terminals; part number KTW-0001
[18 in (46 cm) leads] and part number KTW-0002 [36 in (91 cm) leads].
