Mechanical installation and maintenance
These instructions are intended for all who install and service the drive.
Printed circuit boards
Fibre optic cables
WARNING! Ignoring the following instructions can cause physical injury or death,
or damage to the equipment:
•
Handle the unit carefully.
•
The drive is heavy. Do not lift it alone. Do not lift the unit by the front cover.
Place the unit only on its back.
• 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 damage to the printed
circuit boards:
•
The printed circuit boards contain components sensitive to electrostatic
discharge. Wear a grounding wrist band when handling the boards. Do not
touch the boards unnecessarily.
WARNING! Ignoring the following instructions can cause equipment malfunction
and damage to the fibre optic cables:
•
Handle the fibre optic cables with care. When unplugging optic cables, always
grab the connector, not the cable itself. Do not touch the ends of the fibres with
bare hands as the fibre is extremely sensitive to dirt. The minimum allowed
bend radius is 35 mm (1.4 in.).
