• 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 proper grounding, 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.
• Removing AC line power is the only acceptable method for emergency stopping. Do not use
• dynamic braking, decelerang to minimum speed, or coasng to a stop for emergency stopping.
• They may not stop a drive that is malfunconing. Removing AC line power is the only acceptable
•method for emergency stopping.
• Line starng and stopping (applying and removing AC line voltage) is recommended for infrequency
• starng and stopping of a drive only. Dynamic braking, decelerang to minimum speed, or coasng
• to a stop is recommended for frequent starts and stops. Frequent starng 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.
• The field output is for shunt wound motors only. Do no make any connecons to F1 and F2 when
•using a permanent magnet motor.
• Change voltage switch sengs only when the drive is disconnected from AC line voltage. Make sure
• both switches are set to their correct posion. If the switches are improperly set to a lower voltage
• posion, the motor will not run at full voltage and may cause damage to the transformer. If the
• switches are improperly set to a higher voltage, the motor will overspeed, which may cause motor
• damage, or result in bodily injury or loss of life.
• Under no circumstances should power and logic level wires be bundled together.

Installation
Mounng
NEMA 4X cased drives come with two 0.73 inch (18.5 mm) conduit holes at the boom of the case.
The drives may be vercally wall mounted using the four 0.19 inch (5 mm) sloed holes on the
aached heat sink. For loads less than 5 amps, the drive may be bench mounted horizontally or
operated without mounng.
1. Install the mounng screws.
2. For access to the terminal strip, remove the six phillips screws on the front cover.
3. Remove the five phillips screws on the boom plate. Do not remove the three screws securing the
3. boom plate to the heat sink.
4. Set the POWER switch to the OFF posion before applying AC line voltage.
5. Install conduit hardware through the 0.73 inch (18.5 mm) knockout holes. Connect external wiring
5. to the terminal block.
6. Place the front cover back into place. Avoid pinching any wires between the front cover and the
6. heat sink.
7. Reinstall the 6 screws on the front cover. The two shorter screws are for the two lower holes of the
7. front cover. Reinstall the 5 screws on the boom plate.
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 praccal to shield power
conductors, it is recommended to shield 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
The drive provides on board fusing for the AC line (L1, L2(230)). Fuses are fast acng fuses rated for
15A at 250 VAC. NOTE: DO NOT make
any connections to
F1 and F2 if using a
permanent magnet motor.
Inhibit
Terminals
Line Input
Connect the AC line power leads to terminals L1 and L2-115 if using 115 VAC line power or to terminals
L1 and L2-230 if using 230 VAC line power.
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 (Pre-wired)
PAT443 series drives are pre-installed with a 10K ohm, 1/4 W potenometer for speed control. Set the switch
on the front cover to MANUAL to follow the potenometer.
Analog Signal
Instead of using a speed adjust potenometer, PAT443 series drives may be wired to follow an analog
input signal. This input signal can be in the form of voltage (0-10 VDC) or current (1-5, 4-20, or 10-50 mA).
Because these drives have built in isolaon, the input signal can be grounded or ungrounded (floang).
Connect the signal common (-) to terminal 3 and the signal reference (+) to terminal 2 on the top board.
If using a 4-20 mA signal, place a 1000 ohm resistor (RSH) across terminals 1 and 4 on the top board.
If using a 10-50 mA signal, place a 250 ohm resistor (RSH) across terminals 1 and 4 on the top board.
Set the switch on the front cover to AUTO to follow the remote analog signal.
Inhibit
Short the INHIBIT terminals to coast the motor to minimum 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].
