NB! Unit will be returned with factory settings after
repair.
The 615 series protection relays consist of several
different parts, the plug-in unit, the case and optional
modules. The optional modules are installed into the relay
case separately and is not a part of the plug in unit. All
mentioned parts together form the product.
In order to make approriate fault investigation and to take
right corrective measures in the repair workshop, the whole
product is needed. Therefore we request users to always send
the whole product for repair and not only some of the parts.
