2.4 Safety Instructions
High Voltage in the Working Area
The transformer is under high voltage when in operation. The transformer
can be under high voltage when in the connected state and not grounded
on the high voltage side. This can cause serious personal injury or death.
Switch off the high voltage source and secure against restarting
prior to any works on the transformer, such as installation,
maintenance and rectification of malfunctions. See chapter
“Installation” in section “Working in a Voltage-free Condition“.
Constructional Modifications
Constructional modifications can affect the functionality and operational
safety of the transformer. This can cause serious personal injury or death.
Adjacent equipment can be damaged as well.
Never perform constructional modifications on the transformer
Deviating Conditions in Operation
Deviating operational conditions can impair the functionality and
operational safety of the transformer. This can cause serious personal
injury or death.
Operate only with the data stated in chapter “Description of the
Transformer" in sections "Technical Data" and "Ambient Conditions”
User manual
GBEAN 12/0...24/0; GBEA 36 Gr. 1
EKM 20170103 Revision: 1 9 / 20
Transport and Assembly
Loads can swivel and fall during lifting operations. Likewise, insufficiently
supported and fixed transformers can fall or tilt, especially at assembly on
a ceiling and/or wall. This can cause serious personal injury or death.
Carry out the transport properly. See chapter “Installation“ in
section “Transport of the Transformer“
Always fixate the transformer. See chapter "Installation“ in section
"Mounting of the Transformer“
Incorrect Connection with the high voltage terminal
Not suitable cable plugs and non-elastic connection with the high voltage
terminal can impair the functionality and operational safety of the
transformer. This can cause severe personal injury or death.
Never apply incorrect forces on the primary terminal, this applies
also in the event of switching and thermal expansion
Always use elastic connection and support the connector cable
Only use matching plugs. See chapter „Installation“ in section „High
Voltage Connection“
Short circuit at Secondary Terminals
Short circuited secondary terminals overload the windings thermally and
the transformer will be destroyed within a short time. This can cause
serious personal injury or death.
Never short circuit secondary terminals. See chapter “Installation“
in section “Secondary Connection“ and “Secondary Connector of
the Earth-fault Winding (Optional)“
High Voltage on the Earthed Terminal of the Primary Winding
The non-grounded earthed terminal of the primary winding is under high
voltage.
Never remove the connection between earthed terminal of the
primary winding and the base plate. See chapter “Installation” in
section “Ground-sided Terminal of the Primary Winding“.
Always ground the earthed terminal of the primary winding.
Always ground the base plate or the housing

Damage on the Transformer
Damage can impair the functionality and operational safety of the
transformer. This can cause severe personal injury or death.
Take damaged transformers out of service immediately.
Contact the manufacturer if necessary (see chapter
“Service/Contact“)
Improper Auxiliary Agents
Auxiliary agents that do not meet the requirements of the manufacturer
may impair the operational safety of the transformer and can cause
accidents. This can cause serious personal injury or death.
Use auxiliary agents only that meet the requirements
Safe Handling of Auxiliary Agents
Depending on the chemical composition, the used auxiliary agents can
pose hazards. This may cause personal injury.
Adhere to the safety data sheets of the auxiliary agents. Observe
all information and regulations given in the safety data sheet
Operation only after proper Start-up
Without proper start-up in accordance with this manual, the operational
safety of the transformer is not guaranteed. This can cause accidents and
may result in serious personal injury or death.
► Use transformer only after proper start-up. See chapter “Start-up“
Technically Faultless Condition of the Transformer
Improper handling or maintenance can affect the operational safety of the
transformer. This can cause accidents and may result in serious personal
injury or death.
Carry out works on the transformer only according to the
instructions
