Note regarding fiber-optic cables
Fiber-optic cable systems are used in some inverters. Please observe the following warning.
Figure 2-3
Erroneous pulses in fiber-optic cables
Erroneous pulses in fiber-optic cables caused by camera flash lights can result in
malfunction and damage to the inverter and motor and potentially result in injury to
personnel.
It is not permissible to photograph inverters with fiber-optic cable systems using a camera
flash light when they are in operation! Only photograph these types of inverters when they
are in a no-voltage state.
2.12
Protecting/fusing the external 230 V AC control voltage
External control voltage without fuse protection
If you use an external control voltage without suitable protection (e.g. fuses), then
overloads and short-circuits can occur. This can result in death, serious injury or material
damage.
The device may only be operated with a protected external control voltage. Note the
following recommendation.
Install one of the following options to protect the external control voltage:
• Miniature fuse in accordance with EN 60127: 2 A ... 6 A, slow, maximum 150 VA
• Miniature circuit-breaker: 2 A ... 6 A, characteristic D, maximum 150 VA
