Before mounting the wiring base, determine the proper orientation
and position as described in Chapter 2.
•
Leave adequate clearances for wiring.
•
The wiring base has four conduit openings. Seal unused conduit
openings with the 3 hole plugs provided with wiring base. Use
cord grips with rubber grommets on cables that enter wiring base.
Two different size grommets are provided with each cord grip.
•
Route wires carefully to reduce or minimize electrical noise.
When communication and power wiring must cross, make their
intersection perpendicular.
•
Proper grounding of the wiring base limits the effects of noise
due to Electromagnetic Interference (EMI). The wiring base has
a ground screw for connecting cable shields and ground wires. To
avoid EMI problems, all cables must be shielded and grounded at
one end. Grounding is also an important safety measure.
