Additional reports for supplementary charge,
made available on request:
• test report on accuracy
• excitation (magnetization) curves
• additional nameplates (if more than 1 is re-
quired)
• verification tests for measuring cores (classes
0.2; 0.2 S; 0.5; 0.5 S)
5. Maintenance instructions
before installation
Excessive dust sediments or any other type of
contamination are to be removed from the trans-
former using a soft brush and alcohol, in such a
way as not to damage the coating and sealing
surface. Protect the sealing surface from both
sides of ELK - CN during manipulation with a
transformer. The spray painted surface inside CT
must be smooth without sharp edges and coarse
defects.

6. Transport & Storage
The permitted temperature for transport and
storage ranges from -55°C to +80°C. During
transport and storage the transformers have to
be protected from direct impact of solar radia-
tion. The transformers are delivered according to
delivery instruction HASV600377.
7. Disposal
Materials used in instrument transformers are
considered as materials without environmental
impact and the materials are not toxic. Instru-
ment transformers have to be disposed of in ac-
cordance with national legislation relevant to do-
mestic waste disposal.
8. Handling
The transformers ELK - CN are too heavy and is
necessary to use hanging belts attached on holes
for screws on three places or to use one or more
hanging belts attached around the flange of the
transformer. For handling use belts and a crane
with sufficient load capacity. Always make sure
that the belts are secured safely on the crane and
on the transformer.
ATTENTION:
During the manipulation with the
transformer it is necessary to follow safety work
instructions. Never stay under the freight. Al-
ways make sure that the freight is safely locked
on the crane and make sure that there is no risk
of unexpected release or turnover of the freight.
Follow the Label Instructions:
