Load capacity for chains/loops/crane must be no
less than 200 kg. Always make sure that chains/
loops are properly and safely attached to the crane's
hook and that the voltage transformer is properly
secured.
Observe the work safety rules during voltage trans-
former handling operations. Never stay under the
suspended loads. Always make sure that the voltage
transformer is safely attached to the crane's hook
and there is no risk of load falling or tipping over.

10. Normative references

Voltage transformers are: designed, tested and manufactured
according to international or national standards specified by cus-
tomers and confirmed by manufacturer. Normative reference for a
given voltage transformer is always indicated on the transformer' s
rating plate.
Standard examples:
IEC 61869-1; IEC 61869-3; IEC 60044-2; GOST 1983-2001.
On requests, voltage transformers may be designed and
manufactured in accordance with other revisions of standard
or standards specified above upon a prior agreement between
manufacturer and purchaser.
