Damage to bolted connections through overtightening
If the permitted torques are exceeded, bolted connections can be damaged. In this case, fault-free operation of the
inverter is no longer ensured.
• Only tighten loose bolted connections to the prescribed torque. Torque specifications are indicated in the
circuit diagram of the inverter. If there is any information missing, contact (see Section 9 "Contact", page 68).
Procedure:
1. Check that the bolted connections of all assemblies are securely in place.
If bolted connections are loose, tighten them using a torque wrench.
2. Check whether all bolted connections of the power cabling are securely in place.
If bolted connections are loose, tighten them using a torque wrench.
3. Check the insulation and connections for any discoloration or change in appearance.
If insulation and connections are discolored or changed, contact us (see Section 9 "Contact", page 68).
4. Check the bolted connections for damage and contact elements for corrosion.
If bolted connections are damaged or contact elements corroded, replace them.
