CENTRAL PROCESSOR PACKAGE INSTALLATION

February 1996
Part No. 004-3039-274
2.4 MOUNTING OF SURGE ARRESTOR BOX-
ES AND GROUND BRACKET
2.4.1 PLACEMENT OF SURGE ARRESTOR
BOXES
The surge arrestor box(es) may be mounted
directly on a wall or on a plywood board at a location
near the central equipment cabinet. (Be sure the
ground lug is on top).
Figure 2-3 gives a general idea of how the Surge
Arrestor Boxes would appear on a typical panel board
complete with the common copper ground bracket
assembly.
2.4.2 WALL OR PANEL BOARD INSTALLATION
Use 1/4" diameter screws (not furnished) to
attach the surge arrestor boxes and the common
ground bracket assembly to the wall. Wall mount key-
holes (see Figure 2-3) are provided on the surge arres-
tor boxes. If the wall is of masonry construction,
again, the use of a plywood sub-panel is recom-
mended.
C A U T I O N
DO NOT mount with the ground lug on the bottom.
