Installation
Mounting
NEMA 1 cased drives come with two 0.88 inch (22 mm) conduit holes at the bottom of the case. The
drives may be vertically wall mounted or horizontally bench mounted using the three keyholes on the
back of the case.
1. For access to the keyholes and the terminal strip, remove the two screws from the front of the case
1. by turning them counterclockwise. Grasp the front cover and pull it straight out.
2. Install the monting screws in the three keyholes.
3. Set the POWER switch to the OFF position before applying the AC line voltage.
4. Install conduit hardware through the conduit holes at the bottom of the case. Connect external
3. wiring to the terminal block.
5. Reinstall the front cover. Avoid pinching any wires between the front cover and the case.
6. Reinstall the two screws on the front cover. Turn the screws clockwise to tighten.
Heat Sinking
The LGD430-10 requires an additional heat sink when the continuous armature current is above 5
amps. Use ACE heat sink kit part number HSK-0002. Use a thermally conductive heat sink compound
(such as Dow Corning 340® Heat Sink Compound) between the back of the case and the heat sink
surface for optimal heat transfer.
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
LGD430 series drives provide fusing for the AC line (1, 3). Fuses are fast acting fuses. LGD430-1.5
models contain fuses rated for 3A at 250 VAC. LGD430-10 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.
• 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
