ULTRA-CUT 400
3.10 Handling and Installation of Fiber Optics
General Information
This kit is for proper handling and installation of Fiber Optic Cables used in Therrmal Dynamics Ultra-Cut ® and
Auto-Cut O2 ® automated gas boxes and Gas Control Modules.
Fiber Optic cable is used in place of wire because it offers far superior immunity to electrical noise but it is more
delicate and requires careful handling. With fiber optics, electrical signals are converted to light with a transmit-
ter LED. The light passes down the fiber where it is converted back to an electrical signal at the receiver end. Any
damage to the fiber from sharp bends or pulling that stretches the fiber can reduce it’s ability to transmit light. We
run the fiber inside a hose for most of its length to protect it from abrasion, burning from hot metal or sharp bends
but the ends are exposed and must be handled with care.

WARNINGS
Disconnect primary power at the source.
Avoid the following:
1. If you need to pull the cable through a power track do not fold the fiber back on itself making a sharp bend
where it exits the hose.
Art # A-09417
2. Don’t hook onto the fiber to pull on the cable.
