Wiring Notes

•To avoid problems associated with EMI (electromagnetic interference), you should route high power lines (AC input power and motor power) away from low power lines (encoder feedback, serial communications, etc.).

•If a neutral wire (not the same as Earth Ground), is supplied from the building distribution panel it should never be bonded with PE wire in the enclosure.

•You should consider future troubleshooting and repair when installing all wiring. All wiring should be either color coded and/or tagged with industrial wire tabs.

•As a general rule, the minimum cable bend radius is ten times the cable outer diameter.

•All wiring and cables, stationary and moving, must be protected from abrasion.

•Ground wires should not be shared with other equipment.

•Ensure that metal to metal contact is made between the enclosure ground lug and the metal enclosure, not simply through the mounting bolt and threads.

•All inductive coils must be suppressed with appropriate devices, such as diodes or resistor/capacitor (RC) networks.

Mechanical Installation

Drive Mounting

Drives must be back mounted vertically on a metal surface such as a NEMA enclosure. A minimum spacing of two inches must be maintained above and below the drive for ventilation. Side by side drive spacing requirements vary by drive size and RMS loading. Additional space may be necessary for wiring and cable connections.

For drive dimensions, weights and mounting specifications, see the "Specifications" section.

Motor Mounting

Motors should be mounted firmly to a metal mounting surface to ensure maximum heat transfer for maximum power output and to provide a good ground.

For motor dimensions, weights and mounting specifications, see the “Specifications” chapter.
