1 General Information
1.1 Validity
These instructions relate to the technical specifications of the
equipment at the time of publication. These instructions are a
component part of the system.
Legal claims arising from this contractual relationship shall only be
recognised by AEG Power Solutions GmbH subject to the terms
agreed under the warranty obligation in the main contract.
1.2 Appropriate Use
The compact station TKS-CS is designed for use in solar power
stations with one or two Protect PV inverters, in accordance with
IEC 62271-202. The compact station is intended for outdoor
installation.
An output-related transformer for electrical isolation and outputdependent medium-voltage switchgear for feeding into the local
medium-voltage mains are installed in the compact station.
The equipment may only be used for this purpose. Any other use
constitutes misuse and can endanger personal safety.

2 Safety
The qualified skilled personnel are responsible for safety.
The member of personnel who is responsible for the equipment
must ensure that only suitably qualified persons are allowed
access to the equipment.
To ensure safety in the electrical operating areas, these areas
should be lockable; i.e. suitable locking systems should be
installed by the owner on all exterior doors of the compact station.
2.1 Installation Location
The equipment is intended for use outdoors as an enclosed
electrical unit.
• Environmental conditions: ( technical data) in accordance
with DIN EN 60721-3-4.
• Freely accessible air vents for heat dissipation.
• Ground pressure: min. 250 kN/m
Refer to the technical data for additional criteria.
When selecting the installation location, regional regulations
governing noise emissions must be taken into account.
Do not install the equipment in areas subject to flooding or those
with a high groundwater level.

( excavation plan)
2.2 Lightning Protection
The connection to the potential equalisation system of the
foundation provides the equipment with effective protection against
lightning strikes.
The manufacturer’s specifications must be implemented effectively
in order to provide the photovoltaic system with suitable lightning
protection measures.
Further safety information can be found in the Protect PV Inverter Operating
Instructions (BAL).
