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)
