Installing the Wiring Base and Power Supply 3–4

There are 2 options for mounting the wiring base (Catalog No.

2755-NB40 or -NB41):

• Top Mounting – Mount the base using 3 screws through the top

mounting holes.

• Bottom Mounting – Mount the base using 3 screws through the

mounting surface into threaded holes on bottom of wiring base.

Top Mounting

The wiring base mounts from the top to any flat surface with three

#10 or M5 mounting screws. The screw heads must be less than 3/8

inch in diameter allowing them to fit inside the mounting hole. The

length of the mounting screws must be 1/2 inch (12.5 mm) plus the

depth the screw penetrates the mounting surface.

Note: The 3 screws provided with the wiring base are suitable for

use with the mounting bracket (Catalog No. 2755-NM42).

A full size mounting template is provided with the wiring base. Use
