Specifications 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 Naonal
• Electrical Code and all other applicable electrical and safety codes, including the provisions of the
• Occupaonal Safety and Health Act (OSHA), when installing equipment.
• Circuit potenals 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 adjusng the calibraon trim pots. Use approved personal protecon
• 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 protecon, thermal protecon, and enclosure. Follow sound maintenance procedures.
• ACE strongly recommends the installaon 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 potenometer tabs do no make contact with the potenometer’s body. Grounding the
• input will cause damage to the drive.

Installation
Mounng
• Drive components are sensive to electrostac 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 calibraon trim pots.
• Mount the drive away from heat sources. Operate the drive within the specified ambient operang
• temperature range.
• Prevent loose connecons by avoiding excessive vibraon of the drive.
• Mount the drive with its board in either a horizontal or vercal 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
• mounng screws to penetrate the anodized chassis surface and to reach bare metal.
Heat Sinking
The PWL400-10 requires an addional heat sink when the connuous armature current is above 5
amps. Use ACE heat sink kit part number HSK-0003. Use a thermally conducve heat sink compound
(such as Dow Corning 340® Heat Sink Compound) between the chassis and the heat sink surface for
opmal 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 praccal to shield power
conductors, ACE recommends shielding all logic-level leads. If shielding of logic-level leads is not
praccal, 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 series drives provide an on board fuse for the AC line (L1) HOT. Fuse is a fast acng fuse.
PWL400-3 models contain a fuse rated for 8A at 250 VAC. PWL400-5 models contain a fuse rated for
10A at 250 VAC, and PWL400-10 models contain a fuse rated for 20A at 250 VAC. If using 230 VAC line
power, fuse the L2 connecon. Use fast acng fuses rated for 250 VAC or higher and 150% of the
maximum armature current.
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 direcon,
power down the drive and reverse these connecons.
Field
At 115 VAC, connect the field leads to terminals F1 and L1 for a 50 VDC field or to F1 and F2 for a 100 VDC field.
At 230 VAC, connect the field leads to terminals F1 and L1 for a 100 VDC field or to F1 and F2 for a 200 VDC field.
Do not make any connecons to F1 and F2 if using a permanent magnet motor.
Speed Potenometer
Use a 10K ohm, 1/4 W potenometer for speed control. Connect the counter-clockwise end of the potenometer
to S1, the wiper to S2, and the clockwise end to S3. If the potenometer works inversely of desired funconality,
(i.e. to increase motor speed, you must turn the potenometer counterclockwise), power off the drive and swap
the S1 and S3 connecons.
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 connecng to the inhibit terminals; part number KTW-0001
[18 in (46 cm) leads] and part number KTW-0002 [36 in (91 cm) leads].
