Allowed usage

• The PVS-100/120 medium voltage compact skid (MVCS) is designed to transform AC
current from a group of inverters and finally feed to a medium voltage grid. Use the
MVCS only at its permissible input/output ratings and ambient conditions. Make sure
this compliance is satisfied before commissioning.

that fulfill all local skill set and safety requirements. Any unqualified personnel must
maintain a safe distance from the MVCS. All activities must be in accordance with the
criteria described in the ABB technical documents and local regulations.
• Make changes to the MVCS only with the direct authorization of ABB. Any alterations
done outside ABB approval will invalid the warranty for the product. ABB is not liable
for any damages caused by these changes.

WARNING!
Before you perform any work in the MVCS, obey the following safety precautions.
1. Clearly identify the work location.
2. Read the safety instructions of the work area and the component you are working on.
See the subsections below and the component-specific manuals.
3. Disconnect and secure against reconnection.
4. Disconnect all possible power supplies (external, auxiliary and inverters) and open all
base fuse switches. Lock the disconnectors in the open position and attach a warning
