Mechanical installation and maintenance


These instructions are intended for all persons that install and service the drive.
WARNING! If you ignore these instructions, physical injury or death, or
damage to the equipment can occur:
•
Handle the unit carefully.
•
The drive is heavy. Lift the drive by the lifting lugs only. Do not tilt the unit.
The unit will overturn at a tilt of approximately 6 degrees. Be careful when
you move a drive that is on wheels. An overturning unit can cause physical
injury.
Do not tilt!
•
Beware of hot surfaces. Some parts, such as heat sinks, are hot for a while
after disconnection.
•
Make sure that dust from drilling, boring and grinding does not go into the
drive. Electrically conductive dust inside the unit can cause damage or
faults.
•
Make sure that cooling is sufficient.
•
Do not fasten the drive by riveting or welding.

Printed circuit boards


WARNING! If you ignore these instructions, damage to the printed circuit
boards can occur.
The printed circuit boards have components that are sensitive to
electrostatic discharge. Use an ESD wrist band when you touch the
printed circuit boards. Do not touch them unnecessarily.
