AC Input Line

The AC line voltage of the input power must be within the specified range and free of voltage transients that exceed this range. If this is not the case, additional AC line conditioning may be required.

The AC input lines are connected to the 3-position terminal strip (L1, L2, GND) located on the bottom plate of the 525 PMC. Power to the 525 PMC and the external drive must be applied at the same time. To ensure proper operation after removing power, wait a minimum of 10 seconds before re-applying power.

NOTE: The application of AC power to the 525 PMC must be simultaneous with application of AC power to the controlled external drive.

Grounding

The 525 PMC is internally grounded. The primary function of proper chassis grounding is to ensure that the earth ground is connected to the AC ground input of the chassis. Ground connections must be made from the chassis ground terminal on each piece of equipment to a unique single point ground.

Connections should use the same gauge wire as the power input wire to the device and not be shared with any other equipment. The motor cable should contain a motor frame ground wire of at least the same gauge as the armature power conductors.

All electrical cabinets and machine elements must be ground bonded together. 2 shows a typical grounding arrangement. To ensure proper grounding techniques, please observe the recommendation of the IEEE Ground Book, ANSI Standards, and the National Electrical Code.
