This chapter presents recommendations and instructions on how to
install and connect equipment to the NEMA Type 1 and Type 4
Single and Dual-Head Bar Code Decoders. The information is
organized by task, and can serve as a useful quick start tutorial to
guide you through system installation and setup. Topics covered
include:

meeting electrical and grounding requirements

installing alternate language LED indicator labels

mounting dimensions

Before Installation:

verify that incoming power source is 100 to 240 volts AC
nominal, 50 to 60 Hz

protect power source with an external fuse or circuit breaker,
rated at no more than 15 amps

connect decoder to its own branch circuit (when possible) to
reduce electrical noise

Install equipment using guidelines in publication NFPA 70E,
Electrical Safety Requirements for Employee Workplaces. In
addition:

do not use signal wiring and power wiring in the same conduit

route incoming power to the decoder using a separate path
from the communication cables (if paths must cross, their
intersection should be perpendicular)
