2.2 Safety Information
This section contains safety information that must be observed at all times when working on or with the product. To prevent
personal injury and property damage and to ensure long-term operation of the product, read this section carefully and
observe all safety information at all times.
Danger to life from electric shock due to live voltage
High voltages are present in the Transformer Compact Station. Touching live components results in death or serious
injury due to electric shock.
• When working on the Transformer Compact Station, always wear suitable personal protective equipment.
• Do not touch any live components.
• Follow the instructions precisely.
• Observe all warning messages on the product and in the documentation.
• Before performing any work on the Transformer Compact Station, ensure that no voltage is present in any of the
devices.
• Ensure that no disconnected devices can be reconnected.
• Ground and short-circuit the Transformer Compact Station.
• Cover or isolate any adjacent live components.
Danger to life from electric shock if the Transformer Compact Station is damaged
Operating a damaged Transformer Compact Station can lead to hazardous situations that result in death or serious
injuries due to electric shock.
• Operate the Transformer Compact Station only if it is technically safe and in good working order.
• Regularly check the Transformer Compact Station for visible damage.
• Make sure that all external safety equipment is freely accessible at all times.
• Make sure that all safety equipment is in good working order.
• Wear suitable personal protective equipment for all work on the devices.
Risk of fire due to failure to observe torque specifications on live bolted connections
Failure to follow the specified torques reduces the ampacity of live bolted connections so that the contact resistances
increase. This can cause components to overheat and catch fire.
• Ensure that live bolted connections are always tightened with the torque specified in this document.
• When working on the device, use suitable tools only.
• Avoid repeated tightening of live bolted connections as this may result in inadmissibly high torques.
Risk of burns due to hot components
Some components of the Transformer Compact Station can get very hot during operation. Touching these components
can cause burns.
• Observe the warning messages on the components.
• When working on the device, use suitable tools only.
• Wear safety gloves when working on the Transformer Compact Station.

Damage to the devices due to sand, dust or moisture penetration
Sand, dust or moisture penetration can damage the devices of the Transformer Compact Station or impair their
functionality.
• Do not open the Transformer Compact Station during a sandstorm, precipitation or when humidity exceeds 95%.
• Only perform maintenance work on the Transformer Compact Station when the environment is dry and free of
sand and dust.

F Point of interconnection
G Utility grid
Only Sunny Central inverters of the CP-JP production series are connected to the Transformer Compact Station.
The inverter converts the direct current into alternating current. The alternating current is then supplied to the high-voltage
transformer. The alternating current is transmitted from the high-voltage transformer to the switchgear and fed into the
utility grid.

The Transformer Compact Station has doors at the front and back.
The Transformer Compact Station and the high-voltage transformer are delivered separately. After the Transformer
Compact Station is mounted, the high-voltage transformer must be installed and connected in the
Transformer Compact Station. The high-voltage transformer is to be pushed into the Transformer Compact Station via the
back of the Transformer Compact Station.

Minimum Clearances for the Transformer Compact Station
Fire hazard due to overheating of cables
Differing cable lengths lead to overheating of the cables. Excessive heat can result in cable fires. Death or serious injury
due to fire can result.
• All line conductors from the inverter to the Transformer Compact Station must be of the same length.
• The cable length between the connection points must not exceed 15 m.

6.1 Safety during Transport and Mounting
Crush hazard due to the Transformer Compact Station tipping over if not transported properly
If the Transformer Compact Station is lifted and transported too fast or without due care, it may sway or tip over.
The center of gravity of the Transformer Compact Station is not in the middle of the device.
• The means of transportation must be designed for the weight of the Transformer Compact Station.
• Do not tilt the Transformer Compact Station or the high-voltage transformer during transportation.
• Transport the Transformer Compact Station and the high-voltage transformer as close to the ground as possible.
• Always use all anchoring points during transportation.
• Avoid sudden, jerky movements during transportation.
Damage to the Transformer Compact Station due to moisture penetration
• Only transport and store the Transformer Compact Station with its doors closed.
6.2 Transporting the Transformer Compact Station
Figure8: Position of the crane hooks
Requirement:
☐ The foundation of the Transformer Compact Station must be ready.
☐ The crane and hoist must be suitable for the weight of the Transformer Compact Station.
