LD-Series Motor Installation Instructions 3 Before You Install the Motor 1. Remove the motor carefully from its shipping container. 2. Visually inspect the motor for any damage. 3. Examine the motor frame, front output shaft, and mounting pilot for any defects. 4. Notify the carrier of any shipping damage immediately. ATTENTION ! Do not open or attempt to open the motor.

LD-Series Motor Installation Instructions Preventing Electrical Noise ElectroMagnetic Interference (EMI), commonly called noise, may adversely impact motor performance by inducing stray signals. Effective techniques to counter EMI include filtering the AC power, shielding and separating signal carrying lines, and practicing good grounding techniques. Effective AC power filtering can be achieved by using isolated AC power transformers or properly installed AC line filters. To help avoid EMI: 1.

LD-Series Motor Installation Instructions 5 Building and Installing Cables Knowledgeable cable routing and careful cable construction improves system ElectroMagnetic Compatibility (EMC). To build and install cables, perform the following steps: 1. Keep wire lengths as short as physically possible. 2. Route signal cables (encoder, serial, analog) away from motor and power wiring. 3. Separate cables by 0.3 m (1 ft) minimum for every 9 m (30 ft) of parallel run. 4.

LD-Series Motor Installation Instructions Installing Your Motor All motors include a mounting pilot for aligning the motor on a machine. Preferred fasteners are stainless steel. The installation must comply with all local regulations and use of equipment and installation practices that promote electromagnetic compatibility (EMC) and safety. ATTENTION ! Unmounted motors, disconnected mechanical couplings, and/or disconnected cables are dangerous if power is applied.

LD-Series Motor Installation Instructions 7 Guidelines for Installation Observe the following for installing the motor. 1. Allow sufficient clearances in the area of the motor for it to stay within its specified operating temperature range. Refer to Receiving and Maintenance Information on page 2 for operating range. Do not enclose the motor unless forced air is blown across the motor for cooling. A fan blowing air across the motor will improve its performance.
