1.10 REPLACEMENT OF THE INTEGRATED SEMI-
CONDUCTOR FUSE
The device has got an integrated semiconductor fuse F1 for each
power unit which is designed protection reasons for the thyristor. If it
has to be replaced, the device shall immediately be disconnected from
the power supply. Before resumption of operation it is responsible for
seeing that all screws are fastened and no unfasten screw are in the
cabinet.

1.11 SHUT DOWN, DIS-ASSEMBLY

If shutting down and dis-assembling the device for the reason of venue
change or for disposal purposes the following safety rules must be
complied with prior to the beginning of all work performed:
ATTENTION MAINS VOLTAGE!
Safety rules for work performed to electrical facilities:
1. Disconnect the device from the power supply (establish a voltage
free status)
2. Secure against re-activation
3. Verify by measurement that there is no voltage present
4. Ground and short-circuit equipment
5. Cover or separate adjacent parts which are under voltage
For dis-assembly, perform the following steps:
1. Separate the device from the 230VAC, respectively 110VAC, power
supply.
2. Separate all other connections.
Electrical connections are thus dis-assembled and now, the device can
be removed by dis-assembly from the overhead rail.

2. SAFETY REQUIREMENTS

2.1 IMPORTANT INSTRUCTIONS AND EXPLANATIONS

For the protection of personnel and the maintenance of good working
order, usage and repairs must be in line with the guidelines, and the
safety requirements listed must be adhered to. The personnel who set
up/disassemble the devices, start them up, operate them, maintain
them, must know and adhere to these safety requirements. All works
may only be carried out by specialist personnel trained for the purpose
and equipped with the tools, appliances, means of testing and materials
required and intended for that purpose.
In these operating instructions, there are important warnings before
dangerous actions. These warnings are divided into the following classes
of hazards:
DANGER
Hazards that can lead to serious injuries or fatal injuries.
WARNING
Hazards that can lead to serious injuries or considerable damage to
property.
CAUTION
Hazards that can lead to injuries and damage to property.
CAUTION
Hazards that can lead to minor damage to property.
