Installation Instructions
Chapter Objectives
In this chapter you will learn how to:
•
Mount the DL5 in a panel or an enclosure.
•
How to wire the DL5 to your control system.
Grounding Grounding is an important safety measure in installing the DL5. As with all
solid-state systems, grounding also helps limit the effect of noise due to
electromagnetic interference (EMI). The DL5 mounting studs and nuts
(once tightened) connect the DL5 chassis to your equipment ground.
Note: The common terminal on the back of the DL5 is not equipment
ground. The common terminal must be connected separately to your power
supply common.
Wire Routing Careful wire routing helps reduce electrical noise. Route all DL5 wiring
separately and away from all high voltage wiring (115VAC or above). Do
not run the DL5 wiring in the same conduit as any AC power wiring (115
VAC and above). When high voltage wiring and the DL5 wiring must
cross, their intersection should be perpendicular. In addition, the data line
wiring (D0-D15) should be routed away from transformers, solenoids, or
other devices that are known to generate electrical noise (EMI).
!
ATTENTION: Fusing the DL5 power wiring is important to
protect both the power supply and the DL5 from damage
should a short circuit occur. Since the DL5 has no fuses, we
recommend you use external fusing.
!
ATTENTION: You must connect the common lead of the
power source to the DL5. Failure to connect the common lead
may result in electrical shock. In addition, the common lead
protects the DL5 from electrical noise. Do not apply power to
the display until all wiring to the DL5 is completed.
