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 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 

  dynamic 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. Dynamic 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. 

•  The field output is for shunt wound motors only. Do not make any connections to F1 and F2 when 

  using a permanent magnet motor. 

•  Change voltage switch settings only when the drive is disconnected from AC line voltage. Make sure 

  both switches are set to their correct position. If the switches are improperly set to a lower voltage 

  position, 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 

Mounting

NEMA 4X cased drives come with two 0.73 inch (18.5 mm) conduit holes at the bottom of the case.

The drives may be vertically wall mounted using the four 0.19 inch (5 mm) slotted holes on the

attached heat sink. For loads less than 5 amps, the drive may be bench mounted horizontally or

operated without mounting.

1. Install the mounting 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 bottom plate. 

Do not remove the three screws securing the

3. 

bottom plate to the heat sink.

4. Set the POWER

 

switch to the off position before applying applying AC line voltage.

5. Install conduit hardware through the 0.73 inch (18.5 mm) knockout holes. Connect external wiring

3. 

to the terminal block.

6. Place the front cover back into place. Avoid pinching any wires between the front cover and the

3. 

heat sink.

7. Reinstall the 6 screws on the front cover. 

The two shorter screws are for the two lower holes of the

3. 

front cover.

 Reinstall the 5 screws on the bottom plate.

Wiring

Use 14 - 16 AWG wire for AC line and motor.

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

PAT440 series drives provide on board fusing for the AC line (L1, L2 (230)). Fuses are fast acting fuses

rated for 15A at 250 VAC.

 

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 direction, 

power down the drive and reverse these connections. 

 

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 connections to F1 and F2 if using a permanent magnet motor. 

 

 

Speed Potentiometer (Pre-wired) 

PAT440 series drives are pre-installed with a 10K ohm, 1/4 W potentiometer for speed control. 

 

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 connecting to the inhibit terminals; part number KTW-0001 

[18 in (46 cm) leads] and part number KTW-0002 [36 in (91 cm) leads].
