Feeder Terminal
Technical Reference Manual, General

Service

When the feeder terminal is used under the conditions specified in section
"Technical data", it is practically maintenance-free. The feeder terminal electronics
include no parts or components subject to abnormal physical or electrical wear under
normal operating conditions.
If the terminal fails in operation or if the operating values considerably differ from
those mentioned in the feeder terminal specifications, the terminal should be
overhauled. All repairs are to be taken by the manufacturer. Please contact the
manufacturer or its nearest representative for further information about checking,
overhaul and recalibration of the terminal.
To achieve the best possible operation accuracy, all parts of a REF
54_ product have been calibrated together. In the event of
malfunction, please consult your relay supplier.
If the feeder terminal is required to be sent back to the manufacturer due to
maloperation, it is essential that the Customer Feedback form, including especially
the Service Report part, is carefully filled in and enclosed with the terminal.
If the transformer terminal is sent to the manufacturer, it has to be
carefully packed to prevent further damage to the device.
