Warnings caution you about conditions which can result in serious injury or death and/or
damage to the equipment, and advise on how to avoid the danger. The following warning
symbols are used in this manual:
WARNING!
Electricity warning warns of hazards from electricity which can cause physical
injury and/or damage to the equipment.
WARNING!
General warning warns about conditions, other than those caused by electricity
which can result in physical injury and/or damage to the equipment.
WARNING!
General warning warns about weather conditions, prohibited maintenance
operations during a typhoon, thunderstorm, snow, rain and electrical storm.
Maintenance in such conditions can result in physical injury and/or damage to the
equipment.
WARNING!
General warning warns about maintenance work on the roof which should always
be done from the outer perimeter, considering the local safety regulations.

Safety instructions 9

Allowed usage
• The PVS980-CS is a compact skid containing: two outdoor 1500 VDC ABB central
inverters, an ABB oil immersed MV transformer, MV switchgear, a monitoring system
and DC connections. The skid connects a PV power plant to a medium voltage grid.
Use the skid only at its permissible input/output ratings and ambient conditions. Make
sure this compliance is satisfied before commissioning.
• The operation and maintenance of the compact skid must be carried out by certified
technicians that fulfill all local skill set and safety requirements. Any unqualified personnel
must maintain a safe distance from the compact skid. All activities must be in accordance
with the criteria described in the ABB technical documents and local regulations.
• Make changes to the compact skid 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.
Safe installation, start-up and maintenance
This section contains the safety instructions which you must follow when installing,
commissioning and maintaining the compact skid. If ignored, physical injury or death may
follow, or damage may occur to the equipment.
• Only authorized electricians are allowed to install, start-up and maintain the compact
skid. Working methods, tools, components etc. must follow the IEC regulations.
• Obey all local safety regulations concerning electrical stations.
• The compact skid should be energized and de-energized only by an authorized person
who has the task-specific instructions for the operation of an MV substation and
permission from the on-site foreperson in charge of electrical work.
￭General safety instructions
WARNING!
Before you perform any work in the compact skid, 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
notice to them. After disconnecting power to the inverters, always wait until the stored
energy of the inverters is discharged. See also, inverters manual.
5. Use protection against any live parts.
6. Take special precautions when you work close to exposed conductors.
7. Measure to ensure that there is no voltage connected.
8. Carry out earthing (grounding) and short circuiting.
9. Issue a permit to work.
