Installation
Mounting
NEMA 4X cased drives come with two 0.88 inch (22 mm) conduit knockout 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 drives may be bench mounted horizontally or
operated without mounting.
1. Install the mounting screws.
2. For access to the terminal strip, turn the slotted screw on the front cover counterclockwise until it is
2. it is free from the case. The right side of the cover is hinged to the case. Pull the slotted screw to
2. open the case.
3. Carefully remove the conduit knockouts by tapping them into the case and twisting them off with
3. pliers.
4. Set the POWER switch to the OFF position before applying AC line voltage.
5. Install conduit hardware through the 0.88 inch (22 mm) knockout holes. Connect external wiring to
4. the terminal block.
6. Grasp the slotted screw and tilt the front cover back into place. Avoid pinching any wires between
5. the front cover and the case.
7. Turn the slotted screw clockwise until tight to secure the front cover.
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 practical to shield power
conductors, it is recommended to shield 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
The drives provide fusing for the AC line (1, 3). Fuses are fast acting fuses. LGC440-1.5 models contain
fuses rated for 3A at 250 VAC. LGC440-10 models contain fuses rated for 15A at 250 VAC.

• 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.
UL/cUL Overload Protection

Line Input
Connect the AC line power leads to terminals 1 and 2 if using 115 VAC line power or to terminals 1 and 3
if using 230 VAC line power.
Motor
Connect the DC armature leads to terminals 4 and 5. 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 7 and 1 for a 50 VDC field or to 7 and 6 for a 100 VDC field.
At 230 VAC, connect the field leads to terminals 7 and 1 for a 100 VDC field or to 7 and 6 for a 200 VDC field.
Do not make any connections to terminals 6 and 7 if using a permanent magnet motor.
Speed Potentiometer (Pre-wired)
LGC440 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].
