Installation

Mounting

• Drive components are sensitive to electrostatic discharge. Avoid direct contact with the circuit
• board. Hold the drive by the 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. Four 0.19" (5 mm) wide slots
• in the heat sink accept #8 pan head screws.
• The heat sink should be earth grounded. Use a star washer beneath the head of at least one of the
• mounting screws to penetrate the anodized heat sink 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, 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

PWL400-15 series drives provide on board fusing for the AC line (L1, 230). Fuses are fast acting fuses
rated for 20A at 250 VAC.

• 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
Armature Horsepower
• Electrical Code and all other applicable electrical and safety codes, including the provisions of the
Range
• Occupational Safety and Health Act (OSHA), when installing equipment.
1/4 - 1 1/2
15.0 • Circuit potentials are at 115 or 230 VAC above earth ground. Avoid direct contact with the printed
1/2 - 3
• 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.
• 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.
.................................1 - 15 seconds
• 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 115 if using 115 VAC line power or to L1 and 230
if using 230 VAC line power. 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.
Field
At 115 VAC, connect the field leads to terminals F+ and L1 for a 50 VDC field or to F+ and F- for a 100 VDC field.
At 230 VAC, connect the field leads to terminals F+ and L1 for a 100 VDC field or to F+ and F- for a 200 VDC field.
Do not make any connections to F+ and F- if using a permanent magnet motor.
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].
