Atmospheric Pollution
Do not install the inverter in an environment, which contains atmospheric pollutants
such as dust, corrosive gases, etc.
Water
Take care to site the inverter away from potential water hazards, e.g. do not install
the inverter beneath pipes that are subject to condensation. Do not install the
inverter where excessive humidity and condensation may occur.
Installation and overheating
WARNING
The inverter
MUST
be front mounted in a vertical position to ensure optimum
cooling.
Ensure that the inverter’s air vents are not obstructed. For the recommended
clearance distances see Figure 2-4 on page 22.
2.4 Harmonic Currents
For details of the harmonic currents with relation to the SINAMICS G110 inverter,
please see Table 9-1on page 74.
2.5 Derating with Pulse Frequencies
For details of derating with pulse frequencies with relation to the SINAMICS G110
inverter, please refer to Table 7-8 on page 70.
2.6 Overvoltage and Trip Levels
The inverter will protect itself from overvoltage and undervoltage. Internal
overvoltage can occur during braking where internal voltages are forced high by
energy from an external load.
WARNING
Although the inverter is designed to protect itself from overvoltage (if correctly
commissioned); connecting the inverter to a voltage supply that is excessively high
could result permanent damage to the inverter and seriously injure the user.
2.7 Overcurrent Trip Levels
The inverter will protect itself from short circuits between motor phases and from
the motor phases to earth. The inverter will also protect itself against motor
overload conditions which can produce excess currents.
