Installation

Chapter Objectives Chapter 6 provides the information needed to mount and wire the

1391B-ES Servo Controller for operation. Since most start-up difficulties

are the result of incorrect wiring, every precaution must be taken to assure

that the wiring is done as instructed. All items must be read and

thoroughly understood before the actual installation begins.

ATTENTION: The following information is merely a guide for

proper installation. The National Electrical Code and any other

governing regional or local code will overrule this information.

The Allen-Bradley Company cannot assume responsibility for

the compliance or the noncompliance to any code, national,

local or otherwise for the proper installation of this controller or

associated equipment. A hazard of personal injury and/or

equipment damage exists if codes are ignored during

installation.

Mounting Mounting dimensions for the 1391B-ES Servo Controller can be found in

Appendix A. Chapter 2 provides information on power dissipation and

environmental specifications. The controller must be located on a flat,

rigid, vertical surface and must not be subjected to shock, vibration,

moisture, oil mist, dust, corrosive vapors, etc. or temperatures that exceed

60° C (140° F) ambient.

Controllers can be mounted adjacent to each other with a minimum

clearance of 0.312” (7.9mm) between units and/or surrounding cabinetry

and non-current carrying surfaces. However, it is recommended that a

space of approximately 1.0” (25.4mm) be left between adjacent units to

allow easy access and removal of the front cover. To allow for proper

airflow, a minimum clearance of 3.0” (76.2mm) is required along the top

and bottom of the unit and any adjacent components.

The transformer that supplies 230V AC, three-phase and 36V AC to each

servo controller must have 3” (76.2mm) of clearance around it and any

adjacent components. This will allow for proper airflow and wiring access.

The transformer can be mounted in either a horizontal or vertical position.
