Chapter 2 Installation
Introduction
This chapter provides information for connecting and mounting the Symbol PL4507 decoder.
General Information
Grounding
The mounting holes for the Symbol PL4507 include exposed copper that may, if necessary, be used to electrically
ground the decoder to the host using metal screws. If installing the PL4507 in a host where there is a potential to
inject ground noise, use nylon or other non-conductive hardware. In this case the PL4507 ground is provided
through the host connector.
Electrical Isolation
Both sides of the Symbol PL4507 decoder board include components and electrical conductors that must be
isolated from contact with components on the host device. See
Electrostatic Discharge (ESD)
The Symbol PL4507 decoder is protected from ESD events that can occur in an uncontrolled environment,
however, use care when handling the module and apply standard ESD precautions such as using grounding wrist
straps and handling only in a properly grounded work area.
Environment
Enclose the PL4507 decoder sufficiently to prevent dust from gathering on the printed circuit board and
components. Dust and other contaminants can eventually degrade performance. Motorola does not guarantee
performance of the decoder when used in an exposed application.
