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
• connecting power cord
• setting communication parameters
• selecting language
• selecting CRT type
• selecting operations to perform
• connecting and configuring scanners
• setting symbology parameters
• customizing setup
• connecting AUX terminal
• connecting host device
• installing and wiring optional I/O modules
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)
