Notes on Safety
AKE 200 devices use the high-voltage line between transformer substations as a communication path for data
and protection signals.
Notes on Safety must be adhered to ensure personal safety and to avoid damage to property during commis-
sioning and use.

Danger of severe personal injury or substantial damage to property
Hazardous voltages may occur in devices. Always observe the instructions given in
"Qualified Electrical Engineering Personnel" below.
Qualified Electrical Engineering Personnel
Qualified electrical engineering personnel must have up to date technical qualifications
as electrical technicians. Only these persons may commission, use, maintain, decommis-
sion and dispose of the device according to the state of the art standards of engineering
in the high voltage power line environment.
Use as Prescribed
The device may only be used for such applications as set out in the user instructions, and
only in combination with equipment that is entended to work with terminal devices,
that comply to IEC 60481 standard.
Correct and safe operation of the product requires adequate transportation, storage,
installation as well as appropriate use and maintenance.
During operation of the equipment, it is unavoidable that certain parts will carry
dangerous voltages. Severe injury or damage to property can occur if the appropriate
measures during commisioning are not taken:
Danger
Make sure, that the equipment is properly connected to ground at all times. The device
is connected via a HV capacitor to the HV line. A permanent ground connection is an
essential precondition to safeguard the user against any high voltages from the HV line.
The product is equipped with an earthing switch. Before opening the housing, the
earthing switch must be switched to position "0". In addition, grounding the housing via
the externally mounted grounding connector is highly recommended.
Danger
This equipment can be supplied by and connected to different independent energy
sources. Before any maintenance work, disconnect the equipment from all energy
sources to ensure that no dangerous voltage is present, in particular the RF input from
the PLC device and the connection to the HV-coupling capacitor.
Even after the power supply has been disconnected, hazardous voltages can still be
present within the device (capacitor storage).
Before making any connections, ground the equipment and the grounding terminal
Note
IP54: Device may only be operated within a temperature range of -40 to +50 degree
Celsius
Note
The limit values indicated in the manual must not be exceeded; that also applies to
testing and commissioning
