18 Safety instructions
•
Beware of the cooling fan blades. The fans may continue to rotate for a while after
disconnection of the electrical supply.
•
Beware of hot surfaces. Some parts inside the inverter cabinet, such as heatsinks of
power semiconductors, remain hot for a while after disconnection of the electrical
supply.
•
Make sure that debris from borings and grindings do not enter the inverter during the
installation. Electrically conductive debris inside the unit may cause damage or
malfunction.
•
We do not recommend that you secure the cabinet by arc welding. However, if welding
is necessary, ensure that the return wire is properly connected close to the weld in
order not to damage the electronic equipment in the cabinet. Also ensure that welding
fumes are not inhaled.
Printed circuit boards
WARNING! Use a grounding wristband when you handle printed circuit boards.
Do not touch the boards unnecessarily. The boards contain components
sensitive to electrostatic discharge
Fiber optic cables
WARNING! Obey these instructions. If you ignore them, equipment malfunction
and damage to the fiber optic cables can occur.
•
Handle the fiber optic cables with care.
•
When you unplug the cables, always hold the connector, not the cable itself.
•
Do not touch the ends of the fibers with bare hands as the ends are extremely
sensitive to dirt.
•
Do not bend the fiber optic cables too tightly. The minimum allowed bend radius is
35 mm (1.4 in.).
