3.0 INSTALLATION

This section describes how to install and remove the module and its

cable assemblies.

DANGER

ONLY QUALIFIED ELECTRICAL PERSONNEL FAMILIAR WITH THE

CONSTRUCTION AND OPERATION OF THIS EQUIPMENT AND THE HAZARDS

INVOLVED SHOULD INSTALL, ADJUST, OPERATE, AND/OR SERVICE THIS

EQUIPMENT. READ AND UNDERSTAND THIS MANUAL IN ITS ENTIRETY BEFORE

PROCEEDING. FAILURE TO OBSERVE THIS PRECAUTION COULD RESULT IN

SEVERE BODILY INJURY OR LOSS OF LIFE.

DANGER

THE USER IS RESPONSIBLE FOR CONFORMING WITH ALL APPLICABLE

LOCAL, NATIONAL, AND INTERNATIONAL CODES. WIRING PRACTICES,

GROUNDING, DISCONNECTS, AND OVERCURRENT PROTECTION ARE OF

PARTICULAR IMPORTANCE. FAILURE TO OBSERVE THIS PRECAUTION COULD

RESULT IN SEVERE BODILY INJURY OR LOSS OF LIFE.

3.1 Wiring

To reduce the possibility of electrical noise interfering with the proper

operation of the control system, exercise care when installing the

wiring from the system to the external devices. For more detailed

recommendations, refer to IEEE 518.

3.2 Initial Installation

Use the following procedure to install the module:

Step 1. Turn off power to the system. All power to the rack as well

as all power to the wiring leading to the module should be

off.

DANGER

THIS EQUIPMENT IS AT LINE VOLTAGE WHEN AĆC POWER IS CONNECTED.

DISCONNECT AND LOCK OUT ALL UNGROUNDED CONDUCTORS OF THE AĆC

POWER LINE. FAILURE TO OBSERVE THESE PRECAUTIONS COULD RESULT IN

SEVERE BODILY INJURY OR LOSS OF LIFE.

Step 2. Mount the terminal board assemblies on a flat panel

(M/N 61C547) or a DIN rail (M/N 61C548). See figure 3.1.

The terminal boards should be mounted to allow easy

access to the screw terminals. Be sure the terminal board

assemblies are close enough to the rack so that the cables

(M/N 61C547 or M/N 61C548) will reach between them

and the Voltage Input module in the rack. The cables are

five feet long. See figure 3.2.
