Fiber optic cables
- Push the drive module into the cabinet and pull it from the cabinet carefully
preferably with help from another person as shown below. Keep a constant
pressure with one foot on the base of the module to prevent the module from
falling on its back. Use safety shoes with metal toe cap to avoid foot injury.
Do not use the ramp with plinth heights which exceed the maximum height
marked on the ramp next to the fastening screw. (The maximum plinth height
is 50 mm when the telescopic ramp is shortest and 150 mm when the ramp is
longest.) Tighten the two fastening bolts of the ramp carefully.
•
Beware of hot surfaces. Some parts, such as heatsinks of power
semiconductors, remain hot for a while after disconnection of the electrical
supply.
•
Make sure that dust from borings and grindings does not enter the drive when
installing. Electrically conductive dust inside the unit may cause damage or
malfunctioning.
•
Ensure sufficient cooling.
•
Do not fasten the drive by riveting or welding.
WARNING! Ignoring the following instructions can cause equipment malfunction
and damage to the fiber optic cables:
•
Handle the fiber optic cables with care. When unplugging optic cables, always
grab the connector, not the cable itself. Do not touch the ends of the fibers with
bare hands as the fiber is extremely sensitive to dirt. The minimum allowed
bend radius is 35 mm (1.4 in.).
