Only qualified electricians are allowed to do this work. Read the
complete safety instructions of the converter. If you ignore the instructions,
physical injury, death, or damage to the equipment can occur.
WARNING!
If you ignore the following instructions, physical injury, death, or
damage to the equipment can occur:
•
The modules are heavy and have a high center of gravity. They topple over easily if
handled carelessly.
•
When removing a module, pull the module carefully out of the cubicle along the
installation stand. Prevent the module from falling.
•
Keep your fingers away from the edge of the module front plate to avoid pinching them
between the module and the cubicle.
•
Use protective gloves! The edges of the module are sharp!
•
Beware not to drop the screws inside the module!
•
Do not tilt the module. Do not leave the module unattended on a sloping floor.
1. Disconnect the converter from the all power sources and make sure it is safe to start
the work. See the safety instructions. Secure the main circuit breaker [Q1] to the
disconnected (racked out) position. If the disconnecting equipment is located outside
the cabinet, make sure that it is in the disconnected position.
Close the inlet and outlet valves of the liquid cooling unit, and drain the cooling circuit.
